1. Show HN: CodeTracer – A new time-traveling debugger implemented in Nim and Rust
URL: https://github.com/metacraft-labs/codetracer
Author: alehander42
Description: Hey!
We are presenting CodeTracer - a user-friendly time-traveling debugger designed to support a wide range of programming languages:
https://github.com/metacraft-labs/codetracer?tab=readme-ov-f...
CodeTracer records the execution of a program into a sharable self-contained trace file. You can load the produced trace files in a GUI environment that allows you to move forward and backward through the execution and to examine the history of all memory locations. They say a picture is worth a thousand words — well, a video is even better! Watch the demo below to see CodeTracer in action:
https://www.youtube.com/watch?v=xZsJ55JVqmU
The initial release is limited to the Noir programming language, but CodeTracer uses an open format for its trace files and we've started community-driven projects which aim to add support for Ruby and Python.
We are also developing an alternative back-end, capable of working with RR recordings, which will make CodeTracer suitable for debugging large-scale programs in a variety of system programming languages such as C/C++, Rust, Nim, D, Zig, Go, Fortran and FreePascal.

2. Show HN: Shelgon: A Framework for Building Interactive REPL Shells in Rust
URL: https://github.com/NishantJoshi00/shelgon
Author: cat-whisperer
Description: I've been working on Shelgon, a framework that lets you build your own custom REPL shells and interactive CLI applications in Rust.
You can use Shelgon to:
- Create a custom shell with only a few lines of code
- Build interactive debugging tools with persistent state between commands
- Develop domain-specific language interpreters with shell-like interfaces
- Add REPL capabilities to existing applications
Getting started is straightforward - implement a single trait that handles your command execution logic, and Shelgon takes care of the terminal UI, input handling, and async runtime integration.
For example, a simple echo shell takes less than 50 lines of code, including a full implementation of command history, cursor movement, and tab completion.

4. Show HN: Open-source, native audio turn detection model
URL: https://github.com/pipecat-ai/smart-turn
Author: kwindla
Description: Our goal with this project is to build a completely open source, state of the art turn detection model that can be used in any voice AI application.
I've been experimenting with LLM voice conversations since GPT-4 was first released. (There's a previous front page Show HN about Pipecat, the open source voice AI orchestration framework I work on. [1])
It's been almost two years, and for most of that time, I've been expecting that someone would "solve" turn detection. We all built initial, pretty good 80/20 versions of turn detection on top of VAD (voice activity detection) models. And then, as an ecosystem, we kind of got stuck.
A few production applications have recently started using Gemini 2.0 Flash to do context aware turn detection. [2] But because latency is ~500ms, that's a more complicated approach than using a specialized model. The team at LiveKit released an open weights model that does text-based turn detection. [3] I was really excited to see that, but I'm not super-optimistic that a text-input model will ever be good enough for this task. (A good rule of thumb in deep learning is that you should bet on end-to-end.)
So ... I spent Christmas break training several little proof of concept models, and experimenting with generating synthetic audio data. So, so, so much fun. The results were promising enough that I nerd-sniped a few friends and we started working in earnest on this.
The model now performs really well on a subset of turn detection tasks. Too well, really. We're overfitting on a not-terribly-broad initial data set of about 8,000 samples. Getting to this point was the initial bar we set for doing a public release and seeing if other people want to get involved in the project.
There are lots of ways to contribute. [4]
Medium-term goals for the project are:
- Support for a wide range of languages
- Inference time of <50ms on GPU and <500ms on CPU
- Much wider range of speech nuances captured in training data
- A completely synthetic training data pipeline. (Maybe?)
- Text conditioning of the model, to support "modes" like credit card, telephone number, and address entry.

6. Show HN: Ariana – A time travel debugger for PY/JS right in VSCode
URL: https://github.com/dedale-dev/ariana
Author: anougaret
Description: Hello HN!
I've recently released and open-sourced a time travel debugging VSCode extension for Python, Javascript & Typescript.
https://github.com/dedale-dev/ariana
It's born from the pain of spending hours reproducing bugs, struggling to read parallel streams of logging across client/server, and managing print/console.log statements.
You can see a short video here: https://www.youtube.com/watch?v=M2gZv7IOo7s
Basically its two parts:
One part CLI called ariana that you install with npm/pip and run alongside your code's run command. For instance ariana python main.py or ariana npm run dev. It then instrumentizes your code using our specialized parsers & small language models (self-hosted version of the server that does that coming soon).
The other part is a VSCode extension^(1). It picks up the traces left from running the code with the CLI. Then it lets you highlight the parts of the code that ran, and just by hovering any expression (or subpart of a complex expression), see which values it took.
Our goals with this are:
1. Make time-travel debugging easy to use for new coders/vibe coders that would never use a normal debugger, let alone some advanced logging.
2. Allow debugging of across the stack, across components, across languages, parallel data flows super easily (typical pain point of maintaining AI agents codebases, multiplayer web games or RL training setups). In prod even some day when we have a more robust feature set.
3. Experiment with agents using time-travel debugging to fix code accurately in one shot without re-running the code or spending tokens producing print/log statements.
4. Make time-travel debugging applicable to fullstack & frontend development (we plan to sync your frontend's visual state with the traces).
Some may ask why not interfacing with debuggers' APIs and instead rewriting code with tracing?
I think it gives us maximal granularity and expressivity in the traces we get from the code to minimize performance issue and avoiding looking at non-sensical things. It also opens the door to using this in production in the future. Of course I'd be happy to discuss that further with you if you worked on similar projects in the past :)

7. Show HN: Fast-agent – Compose MCP enabled Agents and Workflows in minutes
URL: https://github.com/evalstate/fast-agent
Author: evalstate
Description: Hello, HN.
I've created fast-agent to make building my own products easier - and remove the friction between defining Prompts, MCP Servers and their composition. It uses a simple, declarative style that's easy to work with and source control - with inbuilt support for the patterns in the Building Effective Agents paper.
Because you can "warm-up" and interact with Agents before, during or after the workflows, it's easy to diagnose and tune Agent prompts and behaviour for later runs. Being able to set these workflows up makes LLM Context Management and Tool Selection a lot easier and can vastly improve output quality for little effort.
For MCP Server developers you can see how different models interpret tool descriptions. There's also MCP Roots support, and it comes bundled with a ChatGPT style data-analysis tool (fast-agent bootstrap data-analysis) as one of the demonstrations.
One of the thing I am most looking forward to is combining MCP data retrieval with Anthropic's Citations API - I think that's going to be an incredibly important feature in a lot of scenarios.
It's been forked from, and and builds upon Sarmad Qadri's mcp-agent framework, and we're collaborating to keep the projects in-sync.
Anyway, I'd love to hear your thoughts and feedback on this project, and eager to hear from potential users, contributors and collaborators.

8. Show HN: Uncloud – Uncomplicated container orchestration without control plane
URL: https://github.com/psviderski/uncloud
Author: psviderski
Description: Hey HN,
I'm building Uncloud — a lightweight clustering and container orchestration tool that lets you deploy and manage web apps across cloud VMs and bare metal with minimal cluster management overhead.
After several years of managing and extending Kubernetes at a unicorn, I realised that I desperately needed a change. All those abstraction layers, unnecessary complexity, boilerplate… I wanted container orchestration to bring me joy again, the way Ansible did when I first tried it a decade ago, or Docker after that.
That’s when I decided to start an experiment that is now called Uncloud. The core design principles I’ve focused on intentionally differ from the traditional container orchestrators like Kubernetes or Docker Swarm:
- No control plane or master nodes – all machines are equal
- P2P state synchronisation
- Imperative operations over state reconciliation (fast feedback, easier troubleshooting)
- Graceful handling of network partitions at the cost of eventual consistency
- No advanced auto-healing or auto-scaling magic – predictable behavior instead
I want well-designed building blocks that just work together. When a service needs high availability, I should be able to scale it across machines and know that if any machine goes down the remaining ones will continue serving traffic. When I deploy, I want immediate feedback, not wondering whether the reconciliation loop will eventually catch up.
GitHub with more technical details and a demo: https://github.com/psviderski/uncloud
It's not ready for production use yet, and I'd really love your feedback:
1. Am I alone in wanting a middle ground: something more sophisticated than basic Docker/Compose but without the operational complexity of Kubernetes?
2. If you've moved from platforms like EKS/Heroku/Render/Fly to self-hosting: what was the breaking point and what did you lose or gain in the transition?
3. If you're using tools like Kamal, Dokku, Coolify, or Dokploy, what are your biggest pain points?

13. Show HN: Stealth Interview
URL: https://www.stealthinterview.ai
Author: oleks_b
Description: Coding interviews are broken.
They're a gatekeeping ritual that has NOTHING to do with actual software engineering. We're forced to memorize obscure data structures and algorithms we'll never use, while being watched like lab rats through screen-sharing.
I got fed up and built Stealth Interview - an undetectable AI assistant that works during technical interviews. It runs silently in the background while you're screen-sharing on Zoom or any other platform. The interviewer sees nothing, but you get the help you need.
THIS is the only way you game the system, because the game is rigged.
This is leveling the playing field.
Real engineers use Google, Stack Overflow, and AI tools every day. Recruiters use AI to screen you out or look for Ivy League grads who barely got any experience but inverting trees in CS102.
We're witnessing the demise of the Leetcode era. Companies are slowly realizing these artificial puzzles don't predict job performance. Until they all catch up, Stealth Interview is here to help you get past these arbitrary barriers.
I built this out of frustration, but also hope - for a future where we judge engineers by what they build, not how they perform in high-pressure algorithm recitals.

14. Show HN: WorkWeave – AI Tinder but for job matching
URL: https://workweave.replit.app/
Author: kbeqiri14
Description: Job market right now is brutal - have been applying to hundreds of jobs on various job boards after being laid off, but barely hear back. Feels like the current system is broken.
Decided to channel this frustration & build an early MVP of a job matching platform that uses an AI agent to match candidates with the most relevant opportunities. How it works (also demo on YouTube https://youtu.be/qjnsgfctAQA?si=jTl2NNgMvLJcTFKR):
- Agent synthesizes data from candidate resume and future job preferences, searches our database of jobs that are most relevant based on the description, assigns a score 0-100% depending how well matched
- Candidates start getting a stream of jobs they are most qualified (80%+ matches). On the other side, recruiters / companies see candidates whose experiences & future preferences best fit each job description (80%+ scores). Each party can then swipe interested or not interested.
- Once matched, candidates can just schedule a 1st round interview with job posters / recruiters.
It does all the heavy duty work of helping both candidates and recruiters quickly pair without having to search through job boards, toss in applications one at a time, or email/DM on LinkedIn to get on someone's radar.
All feedback / thoughts and ways to improve encouraged & welcome :)

Author: drbartha
Description: Hi HN,
I am the creator of DrBartha Toys: a software-enabled coding brick system designed to introduce children to programming through hands-on play. Our system bridges the gap between physical and digital learning, making coding more accessible and fun.
How It Works:
Kids can build programs like LEGO: stacking magnetic coding bricks into a tower that represents a sequence of instructions. With concepts like loops, conditionals, variables, and functions, they can create logic that runs on our CodePad, controlling games and interactive tasks.
https://www.kickstarter.com/projects/denesb/drbartha-toys-so...
Thinking About a "Pro" Version for Programmers:
While working on the kids' version, I started wondering:
- Would professional programmers be interested in a physical programming kit that can:
- Solve mathematical problems and real algorithms
- Execute real code (beyond simple logic gates)
- Create physical graphs or networks (would be great for visualizing neural networks, play with graph algos)
- Act as a tangible way to "feel" computation
- I will open-source the task and game creation, allowing anyone to design and share new challenges!
I have always loved physical interfaces for abstract concepts, and I think a hands-on, programmable brick system for professionals could be an interesting tool for problem-solving and teaching. Would this be something you would find useful?
Would love to hear your thoughts! <3

Description: We’re building an open-source tool that makes it easy to expose secure, LLM-optimized APIs on top of your structured data—without manually designing endpoints or worrying about compliance.
AI agents and LLM-powered applications need structured access to data, but traditional APIs and databases weren’t built with AI workloads in mind. Our tool automatically generates APIs that:
- Filter out PII & sensitive data to comply with GDPR, CPRA, SOC 2, and other regulations.
- Provide traceability & auditing, so AI apps aren’t black boxes, and security teams stay in control.
- Optimize for AI workloads, supporting Model Context Protocol (MCP) and REST endpoints with extra metadata to help AI agents understand APIs, plus built-in caching, auth, security.
Would love to get your thoughts and feedback! Happy to answer any questions.

Author: nestoras_design
Description: Hey everyone!
I’m Nestoras, the creator of colorize.design a tool that extracts color palettes from any website. Just enter a URL, and it generates color palettes based on the site's design. Several palettes are created by analyzing both the visual layout (dominant colors from the favicon and homepage screenshot) and the website's HTML, CSS, and JS files.
This project was born out of my own frustration. Whenever I came across a beautifully designed website, I wanted an easy way to grab its color palette without manually inspecting elements or using browser extensions.
How it works: Uses Puppeteer to load the website, take a screenshot, and extract dominant colors. Groups colors using a nearest color algorithm to reduce redundancy and improve the palette. Extracts colors directly from the website’s CSS, HTML, and JS files. Allows users to edit extracted colors and download the full palette. Offers an API for developers who want to integrate this into their workflow.
I’d love to hear your thoughts! Any feedback on the user experience, design, or overall presentation would be super helpful. What features would make this more useful for you? Let me know what you think.

Author: shreymodi
Description: We want to make contributing to open-source easier, especially when dealing with complex, large-scale codebases. To help engineers better grasp the technical workings of these projects, we've created MiniCode—a set of mini-repositories that replicate essential functionalities of larger codebases in a simpler form.
We're starting this initiative by launching a mini-repo focused on Vercel's Next.js. This mini-project aims to offer a hands-on, practical approach to understanding Next.js internals and structure. We've observed that engineers often struggle with onboarding onto large codebases because passive documentation doesn't always provide the needed clarity. Actively building or exploring smaller, MVP-like versions can significantly improve comprehension, encouraging engineers to become more versatile and generalist in their skills. This philosophy drove us to develop MiniCode.
We would genuinely appreciate any feedback, insights, or suggestions from the community as we continue to build out mini-versions for other prominent open-source projects in the future. Let us know if it was helpful for you or any changes that you would like to see!

URL: https://github.com/timeplus-io/proton/blob/develop/src/IO/Kafka/AwsMskIamSigner.cpp
Author: jovezhong
Description: In 2023, AWS announced[1] IAM authentication for MSK Kafka clusters with support for "all programming languages"… except C++. While Java[2], Python[3], Go[4], and others got official SDKs, C++ developers/vendors were stuck hardcoding SCRAM-SHA credentials in code/configs or relying on heavier Java-based tools like Kafka Connect or Apache Flink.
Later, community projects added Rust[5] and Ruby[6] support. Why no C++? Rust might be the new favorite, but C++ is still king for high-performance data systems: minimal dependencies, lean resource use, and raw speed.
At Timeplus, we needed IAM auth for our C++ streaming engine, Proton, so we built it ourselves. Today, we’re open-sourcing our code for AWS MSK IAM authentication. It’s live in Timeplus Proton 1.6.12
Just attach an IAM role to your EC2 instance or EKS pod, then put the Timeplus Proton single binary inside, start the server, then run the following SQL to read or write MSK:
CREATE EXTERNAL STREAM msk_stream(column_defs) SETTINGS type='kafka',topic='topic2', brokers='prefix.kafka.us-west-2.amazonaws.com:9098', security_protocol='SASL_SSL', sasl_mechanism='AWS_MSK_IAM';
The core logic is just two files under 200 lines and you can reuse the code anywhere. https://github.com/timeplus-io/proton/blob/develop/src/IO/Ka... https://github.com/timeplus-io/proton/blob/develop/src/IO/Ka...
We’d love to get your feedback and work together to make this a standalone library—or even get it into ClickHouse or AWS SDK for C++.
For those curious about Timeplus Proton: it’s an open-source streaming engine we built in C++ (think “FlinkSQL in C++” meets ClickHouse’s columnar storage). Later this month, we will also open-source our C++ code for Apache Iceberg read&write. Stay tuned.

41. Show HN: Fractal Reader – Your articles summarized from birds-eye to detail view
URL: #
Author: blu3mo
Description: Hi HN,
I've built Fractal Reader, a tool that creates zoomable, multi-level AI summaries for articles and academic papers.
https://www.fractal-reader.com
Problem: Existing summarization tools typically offer a single summary, which is often too vague or too detailed.
Solution: Fractal Reader generates multiple zoomable summaries—from a quick one-sentence overview to detailed paragraph-level summaries—allowing you to seamlessly zoom in or out on content based on your needs. Quickly grasp the big picture, then selectively explore deeper insights without re-reading entire sections.
The demos probably illustrate it best:
Summary of "Attention Is All You Need" Paper
https://www.fractal-reader.com/view/d9bccd98-8580-4c0a-a366-99b0b73a865e
Summary of "Do things that don't scale" Essay by Paul Graham
https://www.fractal-reader.com/view/184e28f3-0540-4368-a654-3dd0d875ba90
Try it out with your own articles or papers here:
https://fractal-reader.com/
---
Under the hood: Fractal Reader leverages Gemini-based summarization in a custom pipeline that intelligently segments text and constructs hierarchical summaries. It's built to smoothly handle both general articles and dense academic material.
I'd love your feedback:
- Does this solve a real pain point for you?
- Can you think of other scenarios or improvements that would make this tool even more valuable?

To solve this, I developed the Revenew app, which has helped me significantly reduce the time spent on these activities.
In the "Projects" tab, I can send clients a link to the "Client Portal" for each project, where they can view all proposals, invoices, tasks progress, hours spent on each activity, and whether those hours have been billed or not.
Managing finances has also become much easier with the transactions module.
No additional fees are charged for any feature usage.

51. Show HN: We built an AI tool to crawl our SEO articles and find places to update
Author: DtNZNkLN
Description: I got tired of spending hours and hours manually inspecting each of our SEO blog posts to find places that we needed to update. Fresh SEO now does it for me. This tool has already saved me dozens of hours, and I’ve only had it for two months.
You just provide Fresh SEO with a link to your sitemap. The tool then indexes your content and makes it searchable.
Fresh SEO has two modes:
- Quick Search: Straightforward string matching. Great for “find and replace” situations like updating mentions of an old price or an old product name.
- AI Search: More sophisticated. Give Fresh SEO a set of directions explaining what you need to update. Then, Fresh SEO analyzes each page, assigns it a score out of 100, and provides a rationale for the score. Great for situations that require more judgement about what needs to be updated. We’re using DeepSeek V3 to power the analysis.
Although the main niche for the product is SEO, we think it could also be useful for keeping documentation up-to-date, which may be more relevant for the HN crowd.
We would love to hear what you think!

URL: https://github.com/pinkiesky/tprompter
Author: r_glr
Description: Hi everyone, I'm excited to introduce you to a CLI-first toolkit I've been writing for myself, but it started growing, and I decided to make it opensource.
The primary purpose is to automate a routine like:
- unit test generation
- commit messages
- changelogs
- commands like "how to unzip this zip in shell" or "run docker node container in interactive mode shell mount npm pack file to root ./tprompter-1.2.0.tgz"
- even "ask suggest a good hackernews title for project based on the provided README" works :)
It has two modes: prompt generation and direct integration with AI API. E.g.,
tprompter ask run node docker mount /home to ./ export port 123456ortprompter agent commit_messagewill return LLM response right in the terminal (and render md!).But
tprompter generate unit_tests --after=chatgptwill generate a prompt with embedded source code and open ChatGPT page with the generated prompt. So, the second is a good thing if you don't want to create API keys or want to leverage the latest features of ChatGPT, but the first one will allow you not to go to a browser.If case you are interested, I would encourage you to check the repo's README; there are a dozen examples and fancy gifs. That's the reason why I put the "toolkit" in the title; there are different ways to do things.
The project's core idea is to use the CLI possibilities, pipes, autosuggestions, fancy response rendering, integration with ChatGPT page, and so on. To be complex but provide simplicity, like Systemd.
There are predefined agents (or templates) like "commit_message" or "summary", but if you want to make your own, there is a templating engine with a catalog.
I would really appreciate any ideas or suggestions. You might contribute now if you want; there are no github actions, but I will check your code by myself at the first stage :)

I find that context switching between PRs is hard due to the mental model I must develop for each PR. I usually find it helpful when the author sits with me and does a high-level walkthrough.
With the tool, you can load a specific diff or a diff against the main branch, and then the tool will generate a PR walkthrough.
Currently, the tool does the following:
- walks through key areas of a PR with a high-level explanation. Opens code and overlays sticky-note-style annotations.
- explains the code architecture with a structured mermaid diagram
- highlights areas the reviewer should look at closely
Looking for critical feedback. Thanks for trying it out!
Cheers, - Priyank & Arthur

Description: Hi HN,
I wanted to share my new project—a multi-player twist on the classic Asteroids game. I built this game on seeing other Indiehackers make cool things and I wanted to learn game development as salty B2B SAAS product manager.
Here’s a quick overview:
What It Is: A multi-player version of the classic Asteroids game where you can battle against bots in real time, human multiplayer coming soon. Dodge asteroids, collect power-ups, and compete for the highest score in a fast-paced arena.
Why I Built It: I wanted to recreate the nostalgic feel of the original Asteroids while adding modern multi-player elements. The project was a fun way to learn about real-time networking and game physics, and I’m curious to see how the community reacts (if at all).
Technical Details:
- Built using Cursor with a combo of Sonnet 3.5 and 3.7. Tts HTML5, JavaScript, WebSockets hosted on render.
* I tried to focused on smooth, fast gameplay and a simple, retro visual style (think vector scanning).
Its barely working: Fair warning its rough, it takes ages to load and there is no loading indicator. The game mechanics can be glitchy, the bots are overzealous and aggressive.
What I’m Looking For: Feedback on the gameplay, suggestions for new features, and thoughts on performance improvements. If you’re into retro games or have ideas for enhancing multi-player interactions, I’d love to hear from you!
You can check out the live version here: https://astro-c9ad.onrender.com/
Thanks for taking the time to try it out. I’m looking forward to your feedback!

66. Show HN: Metaport – proactive upgrades and patching for PMs
Author: theruss
Description: Hey folks!
Like many of you I guess, having worked several development roles since the late 90s mainly on OSS stacks, I would see the same behaviour over and over where teams promised the earth in RFPs, delivered a super shiny thing approximately on time and on budget, but amazingly, put little-to-no effort into anything more than barely keeping the lights on.
Teams would be barely satisfying their SLAs, occasionally risking security and certification mandates as a result, which were set down at project commencement.
Fast forward to 2023 and my manager at the time is banging her head against the desk having encountered an easily avoidable situation for the nth time: Some key software component is close to, or is already out of support and the client isn't happy (it was sometimes the client who noticed it first...).
I suggested a quick-win -- a spreadsheet which tracked the EOS and EOL dates of each component and presented it as a gantt chart. PMs and DLs would then use that to present to clients well-ahead of key dates so that upgrades and budgets could be discussed proactively. I duly delivered the sheet while still not quite believing such a thing didn't already exist.
Now of course being a developer, I was already thinking about how best to automate this. I had already found a potential means of obtaining pertinent data, and having used an internal tool at a previous company intended for tracking security advisories as well as other useful data-points for Drupal CMS, I decided to roll everything into a single system. It had previously struck me as being odd that this internal tool was Drupal specific. Why wasn't it framework, language or runtime agnostic? The company after all produced software using a variety of technologies. I had made attempts to get internal resource aimed at patching and improving the product which ended up not working out. So as one does, I took the best ideas of the software, made it language agnostic and rolled portfolio-wide EOL/EOS charting and dependency and vulnerability search into a single tool and named it "Metaport".
Metaport CE is in beta and I'm really keen to get people playing with it who are not me. Does it really help in the way it purports to, and for the right people? Could it be architected differently to support say multi-tenancy? (I probably know the answer to this). Metaport is built with PHP and React and is available as a Docker image. Development, evaluation and install instructions are here: https://getmetaport.com/#install and the docs are at https://docs.metaport.sh/.
Super happy to get feedback!

Description: Hey HN!
We built Inferable to tackle some common challenges when putting AI systems into production. It's an open-source platform with a managed control plane to help simplify the development of reliable AI applications.
After working on several LLM-based projects, we kept running into the same issues:
- Workflows crashing and losing state
- No good way to pause execution for human approvals
- Need to build the same boilerplate for human approvals
- Difficulty managing the lifecycle of long-running processes
- Can't get structured output out reliably from every LLM
- Repeated effort building infrastructure for structured outputs
We built Inferable to address these with:
- Persistent workflow state that survives crashes and restarts
- Built-in human-in-the-loop functionality for approvals
- A distributed architecture that separates orchestration from execution
- Standardized methods for extracting structured data from LLMs
Your code runs in your infrastructure while our control plane handles the orchestration. If you're familiar with temporal, think of it as temporal with higher-level LLM-native primitives.
Everything is open-source (MIT license), and self-hosting options are available if you prefer to run it all yourself.
Would appreciate feedback from anyone building AI applications with similar challenges!

Description: Hey HN,
I built a Chrome extension called Folder Manager for Google Docs that lets you organize your Google Docs into folders, something Google Docs (surprisingly) still doesn’t support natively.
Why I Built This
I use Google Docs a lot, but managing documents inside Drive is slow and frustrating. There’s still no proper way to organize documents into folders, quickly move files. I searched for existing solutions but couldn’t find anything simple and effective, so I decided to build one.
How It Works
- Collapsible sidebar to quickly organize your Google Docs into folders
- Easily move and manage documents without digging through Drive
- Pin folders for faster access
I built this primarily for myself, but after using it for a couple of months, I realized others might find it useful too. It’s still a work in progress, and I’d love to hear your feedback—especially on features or improvements you’d like to see!
Give it a try and let me know what you think. Happy to answer any questions!

Author: thrgreenwald
Description: Hey folks, we are building a platform for running e2e tests with multimodal LLM agents / natural language. Released our SDK recently and would love for some people to give it a shot and let us know what you think.
Basically you can define a test in natural language steps, run the test, and the LLM will carry out the test case by observing browser screenshots and taking actions. If it runs into issues or bugs the test case fails with a descriptive problem. We aim to eliminate the flakiness of existing paradigms like playwright/selenium by letting the LLM decide what to do based on what it observes to follow the test case. This way if you make a feature change or some selectors change around, the test case should still work and you don't have to update tests all the time.
