1. Show HN: A blocklist to remove spam and bad websites from search results
URL: https://github.com/popcar2/BadWebsiteBlocklist
Author: popcar2
Description: Hi HN!
I've been fed up with search results so much that I decided to make a giant blocklist to remove garbage links by using uBlacklist.
I browsed other blocklists and wasn't very satisfied from what exists now; the goal of this one is to be super organized and transparent, explaining why each site was blocked via issues. Contributions welcome!
Even though around 100 domains are blocked so far, I already noticed a big improvement in casual searches. You'd be surprised how some AI generated websites can dominate the #1 page on DuckDuckGo.

2. Show HN: WASM-powered codespaces for Python notebooks on GitHub
URL: https://docs.marimo.io/guides/publishing/playground/#open-notebooks-hosted-on-github
Author: mscolnick
Description: Hi HN!
Last year, we shared marimo [1], an open-source reactive notebook for Python with support for execution through WebAssembly [2].
We wanted to share something new: you can now run marimo and Jupyter notebooks directly from GitHub in a Wasm-powered, codespace-like environment. What makes this powerful is that we mount the GitHub repository's contents as a filesystem in the notebook, making it really easy to share notebooks with data.
All you need to do is prepend 'marimo.app' to any Python notebook on GitHub. Some examples:
- Jupyter Notebook: https://marimo.app/github.com/jakevdp/PythonDataScienceHandb...
- marimo notebook: https://marimo.app/github.com/marimo-team/marimo/blob/07e8d1...
Jupyter notebooks are automatically converted into marimo notebooks using basic static analysis and source code transformations. Our conversion logic assumes the notebook was meant to be run top-down, which is usually but not always true [3]. It can convert many notebooks, but there are still some edge cases.
We implemented the filesystem mount using our own FUSE-like adapter that links the GitHub repository’s contents to the Python filesystem, leveraging Emscripten’s filesystem API. The file tree is loaded on startup to avoid waterfall requests when reading many directories deep, but loading the file contents is lazy. For example, when you write Python that looks like
python<p>with open("./data/cars.csv") as f: print(f.read())<p># or<p>import pandas as pd pd.read_csv("./data/cars.csv")<p>
behind the scenes, you make a request [4] to https://raw.githubusercontent.com/<org>/<repo>/main/data/car....

4. Show HN: Simplex: Automate browser workflows using code and natural language
URL: https://www.simplex.sh/playground
Author: marcon680
Description: Simplex is an SDK that provides low-level functions you can use to create reliable web automations using code and natural language.
Here's a quick video to show you how it works: https://www.loom.com/share/8d27d0f9e0f34c77a81b0ac770151c12
A couple weeks ago, we needed a way to automatically find 3D assets from the internet for one of our work contracts. We didn’t need an AI to choose all the steps for us autonomously — we knew generally what the flow to find items should be and just needed some intelligence to handle different webpage formats.
Playwright couldn’t easily generalize to the different sites we wanted to search over and Claude computer use was tough to use — it was slow, expensive, struggled to click on the correct web elements, and there was no way to correct its actions if it failed at step 20 of our workflow.
So we built a vision-based solution using vision language models that sits on top of Playwright. In our SDK, building a function that can universally search websites is as easy as this:
from simplex import Simplex
simplex = Simplex(api_key="api_key")
def search(website, search_query):
simplex.goto(website)
simplex.click("the search bar")
simplex.type(search_query)
simplex.press_enter()
search("mit.edu", "alyssa p hacker")
We'd love feedback!

6. Show HN: Making AR experiences is still painful – had to make my own editor
Author: boriskourt
Description: Hey HN!
My co-founder and I have spent over a decade building mixed reality projects and have been growing more and more frustrated with the process. From the number of tools needed, to client sign-off, to the complex esoteric tech stacks. And especially how slow the iteration loop is when dealing with interactivity and UX.
Two years ago we decided to stop whining and fix the fundamental issues. Ordinary Objects [0] was built with our core needs for AR prototyping: a very tight iteration loop between editor and real device, real-time interactivity while editing and clear and concise flow management + mapping. There are many things that layered on to make all of that possible: making it multi-user from the ground up, handling assets without a fuss, and building up a new interaction language.
From a technical standpoint we wanted to be native on the all of the platforms that we support, and do that as quickly as possible. Two years ago the best tool to achieve that was Unity, and I believe that is still the case today. Everything else is inside our custom C# Redux implementation. Our multi-user needs are very different from games, and it helped a lot to learn from Figma's technical notes to implement our pseudo eventual consistency setup. Its been super nice to be multi-user from the get go, we've been able to explore much more functionality this way.
Once the core churn eases up a bit more we will be open sourcing this particular C# Redux setup. As it has nothing to do with any engine code.
The website has some quick examples of how the design tool works [0]. But if you want to view a more complete prototype here is something Gregor, my co-founder, put together recently [1].
Over the past year we've been testing with closed groups, and have been excited by what everyone is making. Now we are ready to open it up for all of you to try! Give it a spin and let me know what you think! And happy to answer any questions here :)

7. Show HN: Open-Source Document Extraction Tool
URL: https://github.com/harishdeivanayagam/rowfill
Author: harishd30
Description: Hi, I'm building an open-source self-hostable document extraction tool powered by LLM.
There are popular data extraction tools and OCR tools in the market. None of them are open source.
Most accounting firms, law firms, insurance, back office, and real-estate folks would like to use a tool like this.
You can add PDF documents, Images, and audio files and create columns to answer questions on documents or extract information into tabular format.
Access to repo: https://github.com/harishdeivanayagam/rowfill Screenshots: https://github.com/harishdeivanayagam/rowfill/tree/master/sc...
Sample use-case: You can upload your invoices or receipts, create custom columns, and click Start Run. The data would be automatically extracted.

8. Show HN: Sculptor – Python library for LLM structured data extraction (MIT)
URL: https://github.com/lightning-rod-labs/sculptor
Author: bturtel
Description: I built Sculptor after repeatedly seeing founders try to hire data scientists for a task that ultimately boiled down to extracting structured data from unstructured text (customer records, social posts, websites, etc) using an LLM API. We ended up reinventing this pattern internally at least three times in the past year, so I published Sculptor as a streamlined, open-source solution:
- Simple schema-based extraction, with parallelization and type validation.
- Multi-step pipelines with filtering or transforms between steps.
- Configure everything in YAML/JSON for easy reuse.
It’s MIT licensed and on PyPI — feedback welcome!

9. Show HN: I built a tool that helps break down your SaaS idea into AI coder steps
Author: juarasw
Description: After struggling to effectively use AI coding tools (Cursor, Bolt, ChatGPT) on larger projects, I realized the problem wasn't the AI - it was the lack of planning out exactly what all the features will be in advance, and how everything will work/look.
I discovered, if I really thought things through, in details (what features, what the frontend will look like, etc.), I would get way better results. (Making proper product requirements documentation)
The tool is simple:
- Describe what you want to build
- Get a clear and structured breakdown of
- features and components
- Use the documentation as a guide and as context for the AI.
Example: Instead of asking "build me a blog", it helps you break it down into:
- Core features
- Sub-components
- Architecture decisions
- Frontend descisions
- etc.
This structure helps me get much better results from AI tools (like bolt.new, Cursor, Lovable, etc.), regardless of which one I'm using. The AI suggestions are more accurate because I'm giving them better context.
I built it for my own projects but figured others might find it useful. You can try it at doc.onlift.co (pay-per-use since it uses AI APIs).
If you decide to use it, let me know what you think of the results!

10. Show HN: Decentralized robots (and things) orchestration system
URL: https://docs.p2p.industries
Author: hannesfur
Description: Hi HN, we build an open-source operating system extension for orchestrating robot swarms fully decentralized.
This first beta version allows you to create fully decentralized robot swarms. The system will set up a wireless mesh network and run a p2p networking stack on top of it, such that nodes can interact with each other through various abstractions using our SDKs (Rust, Python, TypeScript) or a CLI.
We hope this is a step toward better inter-robot communication (and a fun project if you have a few Raspberry Pis lying around).
Our mesh network is created by B.A.T.M.A.N.-adv and we’ve combined this with optimized decentralized algorithms. To a user, it becomes very easy to write decentralized applications involving several peers since we’ve abstracted away much of the complexity. Our system currently offers several orchestration primitives (Key-Value Store, Pub-Sub, Discovery, Request-Response, Mesh Inspection, Debug Services, etc.)
Internally, everything except the SDKs is written in Rust, building on top of libp2p. We use gRPC to communicate between the SDKs and the CLI, so libraries for other languages are possible, and we welcome contributions (or feedback).
The C++ SDK and a ROS package that should feel natural to roboticists are in the works. Soon we also want to support a collaborative SLAM and a distributed task queue.
We’d love to hear your thoughts! :)

20. Show HN: Maestro – A Modular All-in-One Kitchen Appliance – Beta Available
URL: https://twitter.com/connor_kapoor/status/1879280401522491772
Author: connorkapoor
Description: Hey HN,
I’m Connor, and I’ve been working on Maestro, a modular kitchen appliance that combines a blender, food processor, stand mixer, and more into one device. This is my first hardware product, and I’m launching it in beta to get feedback from early users.
What is Maestro? It’s a single, compact device with a modular design, allowing you to swap attachments for different tasks like mixing, chopping, blending, and more. The base unit houses a powerful motor and a planetary gearbox that adjusts speed and torque based on the task. It’s designed to reduce countertop clutter and eliminate the need for multiple single-purpose appliances.
Why I Built This: I love cooking but found my kitchen overcrowded with appliances I used very little but still wanted to keep around for when i did need them. I wanted a solution that was versatile, compact, and futureproof. Over the past year, I prototyped a device that could handle multiple kitchen tasks efficiently. This project started as a personal solution and grew into something I wanted to share.
What’s Different? Modularity: One base, multiple attachments, and future expandability. Performance: A universal motor and a multi-speed gearbox provide the right torque for every job. We can hit 10,000+ rpm for blending, and go as low as 10 rpm for mixing, which is the widest range of any available appliance to date.
How to Try It We’ve launched the beta program, where you can test the Maestro and share feedback to help refine the final version. For now, you can explore the details and join the beta here: https://mykitchenlab.com/blog/maestro-beta-launch
Backstory and Journey This is a fully bootstrapped project. I 3D-printed the prototypes, developed the mechanical design, and worked through iterations to balance power and versatility. This included many iterations of universal motor speed control, which is a very finnicky thing to get right. Hardware is tough, and I’ve learned a lot about design, manufacturing, and user feedback along the way.
I’ve also documented some of the process and shared technical details here: Previous HN Posts: https://news.ycombinator.com/item?id=40964411 https://news.ycombinator.com/item?id=40729528
I’d love to hear your thoughts! Whether it’s feedback on the design, technical questions, or suggestions for improvement, I’m all ears. Hardware is a journey, and I appreciate the input of the HN community to make Maestro even better.

URL: https://hackernews-daily.thepodcastcollective.com/
Author: rolandpeelen
Description: Hey HN!
Started out with an idea over the holidays to start building a system that creates daily digests of content I follow as a podcast, such that I can listen to it when commuting.
The first one is one that takes the top articles of HN in the last 24 hours and builds them into a podcast. It took forever to tweak it in such a way that it doesn't sound 100% AI, isn't too sensational, but also not extremely boring. I've been tweaking over the past weeks to get it just right and I'm pretty happy with what comes out of it now. I've just submitted / got them all up and running on Spotify and Apple Podcasts and so kind of - launching it?
- Apple Podcasts link: https://podcasts.apple.com/us/podcast/hackernews-daily/id179...
- Spotify Link: https://open.spotify.com/show/6WQFgIvfC2NiMCFRINre5P?si=3f71...
I have some future ideas that would make this even better for me
- Build more shows like this (next is probably a daily digest of news in and around Amsterdam - as I live there). Possibly in such a way that you could create a tailor made podcast. Like, 3 HN articles, Weather in Amsterdam, and 2 Amsterdam news articles, or something like that.
- Build some integrations, so it can be a bit more personal. Like, my current location for the weather, or maybe even my calendar for a personalized intro message.
Would love to hear your questions, thoughts, ideas, and things that can be improved!

41. Show HN: Open-Source AI Resume Parser
URL: https://github.com/orasik/resume-parser
Author: Oras
Description: I wanted a resume parsing service that is cheap, flexible, and scalable without committing to monthly subscriptions. I couldn't find one, so I built one.
Resume parsing is expensive and requires monthly fees. For low volume, it can cost around $0.10 per resume. Using this API, the cost is at least 100x cheaper with no monthly commitment.

44. Show HN: PgDog, Load Balancer for PostgreSQL
URL: https://github.com/levkk/pgdog
Author: levkk
Description: Hi HN,
Another month on sabbatical, another Rust project for y'all to have fun with. This time, I decided to write a load balancer for PostgreSQL. It's called pgDog, and it's everything I learned about running Postgres at scale, in form of software.
pgDog can proxy hundreds of databases, split traffic between primaries and replicas, and reroute queries around hosts experiencing problems, like hardware failure. It speaks Postgres, so much like pgbouncer, and its "spiritual predecessor", PgCat, it can pool transactions and allow tens of thousands of clients to use one database.
Support for more exciting features like sharding is on the roadmap, and with its very own plugin system, pgDog can be customized to arbitrarily send queries to any database in its configuration (or even block queries and return custom results). The plugins are shared libraries loaded at runtime, so they can be written in any language that can expose a C ABI, e.g. Rust, C++, Zig, Java, Go, Ruby, Python, etc.
Documentation is on https://pgdog.dev. The project is of course free and open source software.
Cheers!
P.S. It's still early days, so if you decide to give pgDog a try in your infra, do run a few load tests first!

48. Show HN: I created a platform to practice for your next tech interview
Author: vermaabhishek39
Description: Hey Folks,
Launching the public beta for Dobr.AI here!
Problem
There are 100 platforms to grind coding problems. But there are no platforms to practice for tech interviews. There are so many new platforms popping up for AI based interviews, but all of them are either too basic or basically a ChatGPT wrapper.
Solution
Dobr.AI is a AI powered interview environment that simulates the FAANG style interviews and allows you to practice for your upcoming interview in a realistic setting, with real-time feedback. It's built by professionals (xFAANG with years of interviewer experience).
Status
Currently it supports Coding and LLD (Machine coding) interviews. I'm adding HLD (System Design) interviews in coming weeks. And so many more interview formats in the coming months.

55. Show HN: Compare Price for HDD, SSD, NAS and More
URL: https://www.bestdiskprices.com/
Author: toutoulliou
Description: Hey everyone! My name is Toutoulliou, and I’m a beginner developer passionate about building websites. To practice and improve my skills, I decided to take on a real-world project: a price comparison tool for tech products like SSDs, HDDs, NAS devices, Micro SD cards, USB drives, and more. I used Django for the backend, TailwindCSS and Flowbite for the design, and even managed the deployment myself using Docker. It was a real challenge, but so rewarding!
My website pulls data from eBay and AliExpress APIs to bring you the best deals on the market. And here’s some exciting news: integration with Amazon is in the works! The goal? To help you find the most competitive prices in just a few clicks, whether you’re looking for a high-performance SSD, a high-capacity HDD, or a Micro SD card for your camera.
In addition to the price comparison tool, I’ve added a RAID calculator to help you determine the ideal configuration based on your storage and data security needs. This is just the first step toward a suite of practical tools that I plan to expand over time.
This website is first and foremost a learning journey for me. Every line of code, every feature added is a new step in my development path. If you have suggestions or ideas for tools to integrate, feel free to share them with me!
Let me know what you think!

58. Show HN: Adversarial voice agents to test your voice system
URL: https://labyrinth.io/agent-demo
Author: AIOdyssey
Description: Wanted to show a cool demo on voice agents to give a taste of what we're building!
Labyrinth is a voice agents testing and simulation platform to help you reliably develop and improve the quality of your voice agents. One of our key features is the ability to create adversarial agents, which can be randomly generated to personify scenarios with your use case, or grounded off of real transcripts, and run in simulations against your own voice agent to produce synthetic conversations.
In this demo, you can get a feel for how these work, and have a manual phone conversation with some agents. Pick one of our preset scenarios or choose your own!
Let me know if you have any feedback, or if you are building voice agents and interested in testing.

61. Show HN: Python-Lotion – A Lightweight Wrapper for Notion API (Beta)
URL: https://github.com/koboriakira/python-lotion
Author: koboriakira
Description: Hi HN,
I’ve started building Python-Lotion, a lightweight Python wrapper for the Notion API.
This project is currently in beta and still a work in progress. The main idea is to provide a simpler and more streamlined way to interact with the Notion API, building on top of the popular notion-client library. • GitHub: https://github.com/koboriakira/python-lotion • Why I built this: I wanted a cleaner, more intuitive interface for my own projects, and thought it might help others too. • What’s next: • Enhancing the documentation to make it more comprehensive and user-friendly. • Expanding functionality for managing blocks within pages, such as creating, updating, and organizing them more effectively. • Feedback: As this is still under development, I’d love to hear your thoughts, suggestions, or use cases that could guide future improvements!
Thanks for checking it out.

62. Show HN: An Agentic AI dataset for deepfake detection
URL: https://huggingface.co/datasets/ninamoss/sleeetview_agentic_ai_dataset
Author: ninamoss
Description: Hi HN!
Really excited for our first dataset release. We're co-founders at Mendit.ai, a small startup in the PNW, we focus on customized and explainable AI models. One thing we noticed as we were building our first product was the need for a curated dataset with diverse resolutions, lighting conditions and scenarios resembling mundane, everyday depictions of characters and objects.
We tried a number of agentic ai frameworks and landed on our own lightweight implementation that first identifies the content properties that are relevant for the use case defined in the prompt and then randomly generates content based on those properties.
An interesting takeaway from our experiments is that the latest LLMs that include reasoning in their response tend to generate noisier outputs than instruction tuned LLMs that generate the output without an in depth plan and explanation.
The dataset can be found on huggingface at: https://huggingface.co/datasets/ninamoss/sleeetview_agentic_...
Keep in mind this is only a first sample, we intend to add new content to the dataset based on community feedback on a regular basis.
Looking forward to any feedback, pointers or insights!

66. Show HN: An Android app that scans your Obsidian notes to set reminders
URL: https://play.google.com/store/apps/details?id=com.notifian&hl=en
Author: perite
Description: I'm an on and off Obsidian user who recently came back to Obsidian again. As flexible as the app is, one thing it can't do is set notifications on mobile devices. The feature seemed to be in demand on forums, reddit, etc but it's not on the Obsidian roadmap. So I figured I'd create a free app to set notifications from your Obsidian notes!
It's called Notifian and it's a "companion app" for the Obsidian Android app. It scans your Obsidian vault folder and identifies reminder properties in your notes to set:
- An initial reminder date/time
- (optional) A recurring schedule for reminders
- (optional) A "stop on" date/time, to stop scheduling reminders
It runs these scans in the background on a recurring interval and, as a bonus, it also has support for the Obsidian "tasks" plugin's task format!
The app just got out of closed testing and onto the play store, so I'd love to get more feedback on it now that it's released!
