1. Show HN: Tetris in a PDF
URL: https://th0mas.nl/downloads/pdftris.pdf
Author: ThomasRinsma
Description: I realized that the PDF engines of modern desktop browsers (PDFium and PDF.js) support JavaScript with enough I/O primitives to make a basic game like Tetris.
It was a bit tricky to find a union of features that work in both engines, but in the end it turns out that showing/hiding annotation "fields" works well to make monochrome pixels, and keyboard input can be achieved by typing in a text input box.
All in all it's quite janky but a nice reminder of how general purpose PDF scripting can be. The linked PDF is all ASCII so you can just open it in a text editor, or have a look at the source code here: https://github.com/ThomasRinsma/pdftris/blob/main/gengrid.py

Author: piebro
Description: Hey there, I'm a big fan of the game Factorio and the beauty of factories in the game. That's why I created a website to artfully visualize Factorio blueprints a few years ago. With the new 2.0 update, a few things broke. I took the opportunity to rewrite everything from Python to JavaScript and support Factorio 2.0 and the Space Age DLC. It's now also possible to easily modify the style of the drawings. Let me know if you find any bugs or if you have ideas for features.

3. Show HN: Kate's App
Author: bhpreece
Description: Caregiving is a natural, human act of compassion and caring, and most of us, at some point, will rely on someone to help us with our health care (> 70%) or be tasked with helping someone else (> 10%).
Kate's App is a tool to coordinate doctor contact information, prescriptions, pharmacies, appointments, notes, and other information with family and caregivers, and do it safely and privately. This is not a clinic portal, and is not associated with any insurance or medical providers.
The app is 95% complete, and is entirely usable as is (for any interested beta users). I intend to clean up the rest of it, and go GA within a few weeks. In the meantime, I would love to answer any questions or hear helpful critiques.
BTW, Show HN is the best.

4. Show HN: TabPFN v2 – A SOTA foundation model for small tabular data
URL: https://www.nature.com/articles/s41586-024-08328-6/link
Author: onasta
Description: I am excited to announce the release of TabPFN v2, a tabular foundation model that delivers state-of-the-art predictions on small datasets in just 2.8 seconds for classification and 4.8 seconds for regression compared to strong baselines tuned for 4 hours. Published in Nature, this model outperforms traditional methods on datasets with up to 10,000 samples and 500 features.
The model is available under an open license: a derivative of the Apache 2 license with a single modification, adding an enhanced attribution requirement inspired by the Llama 3 license: https://github.com/PriorLabs/tabpfn. You can also try it via API: https://github.com/PriorLabs/tabpfn-client
TabPFN v2 is trained on 130 million synthetic tabular prediction datasets to perform in-context learning and output a predictive distribution for the test data points. Each dataset acts as one meta-datapoint to train the TabPFN weights with SGD. As a foundation model, TabPFN allows for fine-tuning, density estimation and data generation.
Compared to TabPFN v1, v2 now natively supports categorical features and missing values. TabPFN v2 performs just as well on datasets with or without these. It also handles outliers and uninformative features naturally, problems that often throw off standard neural nets.
TabPFN v2 performs as well with half the data as the next best baseline (CatBoost) with all the data.
We also compared TabPFN to the SOTA AutoML system AutoGluon 1.0. Standard TabPFN already outperforms AutoGluon on classification and ties on regression, but ensembling multiple TabPFNs in TabPFN v2 (PHE) is even better.
There are some limitations: TabPFN v2 is very fast to train and does not require hyperparameter tuning, but inference is slow. The model is also only designed for datasets up to 10k data points and 500 features. While it may perform well on larger datasets, it hasn't been our focus.
We're actively working on removing these limitations and intend to release new versions of TabPFN that can handle larger datasets, have faster inference and perform in additional predictive settings such as time-series and recommender systems.
We would love for you to try out TabPFN v2 and give us your feedback!

6. Show HN: Ultra-portable Gantt chart tool for very regulated environments
URL: https://github.com/aerugo/simplegantt
Author: aerugo_
Description: I work for government agency with a lot of security considerations. We can't install anything and using public webapps is out of the question. Going through clearance or procurement to buy or install something is a pain.
I needed a project management tool, and what we had on offer was too clunky and old. I built SimpleGantt to be ultra lightweight and portable. It's one HTML, one Javascript and one CSS file. Each project is saved into a single .yaml file.
If you have a SharePoint environment you can "host" it by uploading the repo to SharePoint after renaming simplegantt.html to simplegantt.aspx. That allows anyone with access to open the tool by simply having the URL.
Try it at: https://aerugo.github.io/simplegantt/simplegantt
This is a couple of days of tinkering, and mostly exists to keep me from going crazy while managing projects with lots of deadlines and dependencies, so don't expect much. But another person in the same position, finding this might lead to calmer days.

8. Show HN: DeepNode – A tool to search smarter and learn better
URL: https://DeepNode.in
Author: iamadityashukla
Description: Hello HN! I recently launched DeepNode - a tool to simplify learning and research with a visual breakdown of any topic (and much more).
Think of it as ChatGPT (AI) + Structure + Google (Web sources)
When learning/searching for something, web searches can be time-consuming. AI chat tools lack structure and visual elements.
DeepNode provides an interactive breakdown of your searches, allowing you to explore the "breadth" of the topic & dive deep into the specifics.
How it works:
- Enter a topic
- Get a visual breakdown of your search
- Dive deep into specifics to expand the search
- Explore the related images and suggested reads
- Take notes on the fly
- Export the whole knowledge map as a doc (Think: your tailored research doc)
Who's it for:
- Developers
- Students and Educators
- Content Creators
- Researchers
- Basically, anyone who's curious...
Hope you have fun searching! Looking forward to any and all kinds of feedbacks.

12. Show HN: AgentScript AI – Build Agents that think in code
URL: https://github.com/AgentScript-AI/agentscript
Author: kedrzu
Description: AgentScript is a new AI Agent framework with a novel architecture to build reliable and secure agents.
Our framework has LLMs generate a plan upfront in code (javascript) which we then parse into an AST and execute in a managed runtime, so one gets built-in state management and better visibility for debugging via the AST.
By making an LLM express execution plan as code, Agents can think more abstractly about the task and do not even need to know all the data to perform operations on it or make decisions.
Data is expressed as local variables and can be passed to tools, which can be normal deterministic functions, or LLM enabled ones, built using LangChain or any other library.
State management and Human in the loop: This is where our approach really shines esp for agents tackling critical/sensitive workflows in regulated space such as fintech, payments & crypto for ex a treasury agent.
Because AgentScript works on AST, not really running the generated code, execution can be paused on each statement or a tool call. It can be serialized and put into a database, then retrieved and resumed from where it stopped. Each tool would be able to store its state, wait for a user interaction, an event, or some time to pass. They will have built in interactivity and approval mechanisms, so it will be easy to add human in the loop.
Here is a video showing how to build AI agents using AgentScript https://youtu.be/b3MlCpBoxNM
Here is a link to our Discord https://discord.gg/hEYMnj62DT
Please give it a spin and help us improve! This is our alpha release. We'd love to hear your feedback on what to build next.
This is our roadmap:
- Execution serialization and deserialization
- More JS features:
- if statements,
for loops,
template literals
arrow functions
unary and binary operators
Input variables
- Tool state
- Tool interactivity
- Observability and debugging
- Python implementation (any python gurus? ping us!)

Description: This is a small experiment I've worked on during my winter vacation. I wanted to see if instead of using Rust / Go / Zig / whatever for development of web tools C#/.NET might be a viable alternative (esp. in terms of performance).
The answer is yes. Right now it's still feature incomplete (so generally I would not make this a too strong statement), but as of today it's faster than the tested competition (rspack, vite, esbuild).

URL: #
Author: uziiuzair
Description: Noodle Spark lets you create custom business applications by describing what you want in plain English. Currently piloting with Google's Bay Area team, we built this to fix a problem we kept seeing: businesses need custom software but can't afford traditional development.
What you can try now:
* Create chatbots, dashboards, and automation tools without coding
* Build and test ideas in minutes instead of weeks
Private Beta Launch:
We're opening access to the first 100 users for free. Early access includes:
* Priority access to new products and features
* Direct channel to our product team
* Input into our product roadmap
* Free access during beta period
In return, we ask for:
* Regular product usage
* Quick feedback calls
* Your honest thoughts
Tech stack:
- Next.js + Supabase backend
- Our custom Seed Spec engine for translating natural language to application logic
- Seed Specification Language - https://github.com/NoodleSeed-com/seedspec
Sign up for beta: https://www.noodleseed.com/
We're a team of 5 engineers who got tired of rebuilding similar business apps. Rather than make another no-code tool, we focused on natural language as the interface. Tell us what you need, and Seed Spec figures out how to build it.
We'd love feedback from the HN community, especially:
1. What kinds of applications would you want to build?
2. Which features would make this most useful for your workflow?

Author: jeanmayer
Description: Hey HN!
I built this because I've seen too many founders struggling to make their pitch decks actually work. You think it’s great, then you pitch it, and investors just... don’t get it.
I’ve been there.
So I made this tool: you upload your deck, and the AI gives you feedback on flow, clarity, and design. It’s like having a pitch coach – minus the $5K consultant fee.
It’s still early days, and I’m constantly tweaking it based on feedback. Give it a try and let me know if it’s helpful (or if it sucks).
Would love to hear your thoughts.

Description: Our team has been doing research on making practical use of autonomous AI agents within UGC game platforms.
We've done some work on Roblox, and recently built a demo on top of HYTOPIA, which is this video.
In the demo we have 3 agents, each able to interact with one another when they come into proximity, have relative awareness of different areas of the world, and can even take directions and interact with players.
We'll be shipping this soon as a plugin on top of the HYTOPIA SDK so others can play with quickly creating their own agents in their own HYTOPIA games for fun, research, etc.
It's definitely early, but something we're pretty excited about and thought HN would like it too!

Description: Just released two utility tools for Firestore that might save you some development time. Not sure the overlap of firestore and go devs but it's been useful for us. As a small startup we are excited to get going on our opensource journey and welcome feedback!
Just seems like some of the data management tools are underdeveloped and everyone is supposed to write their own. Thought it would be good to build a community around building new ones.
firestore_doc_deleter - A Go-based tool for safe document operations featuring:
Batch deletions with configurable rate limiting
Automatic document backups before deletion
Subcollection handling
Dry-run mode for operation verification
Document restoration from backups
firestore_restore - A web interface (Go backend) for:
Database restoration/transfer operations
PITR (Point-in-Time Recovery) support
Collection/document level granular control
Progress monitoring and batch processing
Service account authentication
The tools are especially useful for dev/staging environments where you need more control over document operations than what's available out of the box.

33. Show HN: AI-Based Observability (new startup launch)
URL: #
Author: notadruid
Description: Hey HN! We’re Ron and Michael from Obics (https://obics.io), an early-stage startup in the observability space. Below is our pitch and we’d love to hear your feedback. We also have an interactive sandbox at https://obics.io/sandbox-intro.
You might think the world doesn't need another observability solution. There are already great ones like DataDog, Elastic, and New Relic. But we’ve come to believe these tools give you suboptimal capabilities. Each modern application consists of many services and “big data”-scale telemetry, and in this landscape, there’s a huge benefit to analytics, event correlation, and advanced OLAP queries.
We think that:
1. There’s a need for an analytics solution for telemetry data (logs, metrics, traces). Once such a solution exists [with low barriers to entry], it could change how we approach production debugging. 2. The mainstream existing solutions can’t provide analytics because their underlying databases are optimized for storage, search/filtering, and basic aggregation. 3. Asking questions in natural language about telemetry data will be extremely useful—if it works well and reliably.
We’ve created a solution where you can get answers to questions like:
- Show me all logs from the last 5 traces where error X happened.
- Look at requests where there was an out-of-memory exception in the last day and break them down by data center.
- How much is the error rate increasing in service “MyService” when the CPU is over 70%?
- What were the most common cart items in sessions where the user added items to the cart but didn’t buy?
Here’s the Obics solution in simple terms:
- Save all telemetry data in a centralized columnar database that allows real-time analytics on big data. We chose ClickHouse.
- Allow ingestion from OpenTelemetry, Prometheus, cloud providers, etc., so you can keep it vendor-neutral.
- Train an AI model on your telemetry data.
And here’s why we think it will work well:
1. ClickHouse uses SQL, and LLMs are very good at generating SQL.
- Since LLMs aren’t 100% reliable, you can’t just ask questions and get answers you can fully trust. But if the LLM generates an SQL query, you can verify it, making the solution as reliable as the query itself.
- ClickHouse doesn’t require a lot of indexing, and it integrates with cheap blob storage like S3. In other words, customers can enjoy the best of both worlds: advanced analytics capabilities and lower pricing.
That’s basically it, looking forward to your comments. You can sign up for a free trial at https://obics.io/freetrial/. We’re also looking for design partners. Thanks.

URL: https://logql.io
Author: xinu2020
Description: Hi HN,
In my recent jobs I've been working mostly on graphQL projects, and despite the technology being more mature now, I wasn't happy with the monitoring in place. So I decided to create my own platform, with a focus on simplicity (as little config as possible to get things in place) and target only GraphQL (generic monitoring platforms that try to also support GraphQL tend to be incomplete or hard to use due to difference between GraphQL and other API paradigms).
At the moment the platform allows to see the latest requests, see operations based on usage, error rate and latency, show the errors, traces (with a breakdown by resolvers) and create alerts based on metrics (with notifications by email, slack or telegram).
How it works:
- Create an account, copy the API key
- Add a plugin to your graphql server (currently only Apollo Server is supported, but the goal is to support as many languages/libs as possible, please let me know in the comments if you're interested but are using another framework!)
- The data are ingested by the platform (internally the stack uses a mix of Clickhouse, Postgres and Redis)
- You can immediately observe the most common operations, traces, errors and create alerts

URL: https://apps.apple.com/de/app/ezlift-pro/id6737275723
Author: mo-adly
Description: Hey guys, my name is Mo. I'm the creator of EzLift Pro. I have been a nerd, software engineer (Mostly Full-Stack) and a bodybuilder/powerlifter for over 15 years now. Long story short: I got bullied in school, so I wanted to get strong af.
I worked in many companies in my career and one of the most consistent thing that always caught my eye is how bad the diet and health of most people are - especially engineers. This made me start a science based fitness YouTube channel to try to spread a more scientific and engineer approachable information about nutrition and training.
Many people were asking me how do I track my workouts. So, I decided to build this app because I tried almost all the popular tracking apps and they all try to target everyone, from beginner to advanced and the app becomes way too bloated.
And because of the boom in popularity of resistance training these days, I was like why not make an app for people who know they are doing in the gym, not complete beginners.
One of the features I'm happy about is scanning your hand-written workouts and workout logs if you use a notebook - although it also works if you scan a picture on your laptop. Then you can track the workout or just add them to your tracked workouts and run some stats on them
I'm using ChatGPT in the backend to scan the image and gets me a list of exercises, then I run that through a small full text search on my database to get a list of ranked matches, it's not 100% perfect, more like 70-80% depending on how difficult the exercise name is.
But if any of you have any ideas on how to make this better, please let me know, would love to have some feedback on that.
It’s available only for iOS for now - I'm not an elitist I swear, just had to start somewhere - I'm just one guy.
I'm using React Native, so adding in Android should be relatively easy.
It’s free for your first 5 tracked workouts. I’d love for you to try it and share any feedback.
PS: If you’re new to lifting and want to start, let me know. I’d be happy to send you a beginner-friendly program to get started!

URL: https://vnsh.io
Author: avigloz
Description: I've always found the concept of dead-drops cool, and figured I could make them accessible to anyone! Securely upload any small text or image content, and share the URL to anyone.
Once someone clicks it, they get to see what you uploaded, but the content is simultaneously deleted from the cloud and becomes inaccessible to anyone else.
More features coming soon!

46. Show HN: "Bolt.new" for Data Extraction from Documents
URL: https://go.sea.dev/
Author: sails
Description: Hi HN.
I’ve been pretty inspired by the likes of http://bolt.new and http://lovable.dev for building applications.
So much so, that we’ve started building an interface on our startup’s data extraction capabilities into a rapid data app.
The idea is to build a fast, flexible and intuitive way to go from having a document, to a flexible data capture pipeline.
The demo page is at https://go.sea.dev/ with a video and demo app.
Three key features
1. Generate a schema from a document or description (the target of the data extraction)
2. Logic and “expert insights” get added to field level descriptions/prompts
3. Ability to share with externals to get data (calendly for data requests!)
The primary feature currently lacking is the ability to iterate on the schema using the chat, it is extraction/RAG/FAQ only.
Some other WIP features:
- Improvements on LLM powered OCR
- Email or WhatsApp data capture
- Embeddable data collection for SaaS
Would love to get your feedback and comments!

47. Show HN: SRTD – Live-reloading SQL templates for Supabase migrations
URL: https://github.com/t1mmen/srtd
Author: t1mmen
Description: We've been happily building on Supabase for ~two years, two major DX frustrations aside:
1. The iteration cycle for database functions was needlessly complex. Some variation of this workflow was common:
- Find existing function/view/policy/etc in past migrations
- Copy to SQL editor
- Make changes
- Test
- Copy back to migration file
- Repeat
Code reviews were painful since every function modification appeared as a complete rewrite. Adding a single line in a 400-line function results in an entirely new file with +401 lines. No historic context, either. Lots of mental overhead for reviewers.
I have searched for tools/workflows to address this, but have came up short. (https://news.ycombinator.com/item?id=36007640, https://news.ycombinator.com/item?id=37755076)
So, over the holidays I paired with Claude to make SRTD (Supabase Repeatable Template Definitions), addressing these issues with a template-based workflow:
# Make a template with safely repeatable SQL echo "-- some idempotent sql" >> supabase/migrations-templates/my_function.sqlEdit your SQL templates, changes auto-apply to local DB
npx @t1mmen/srtd watch
Generate standard Supabase migrations when ready
npx @t1mmen/srtd build
Key features:
* Live-reload for SQL templates (great for functions, policies, views, etc)
- Single source of truth for database objects, with history/functional git blame.
- Standard (Supabase) migrations as output
- Safe iteration with WIP templates that never generate migrations (.wip.sql)
20250109104647_migration_name.sql formatted migrations with some configuration adjustments.Happy to accept PR or issues for other migration file formats (or even DBs).

Would love to hear your thoughts, feedback, and ideas for improvement!

49. Show HN: Copywork – an app that helps you write like your favorite author
Author: zoeangelis
Description: Hey HN,
I’m an aspiring writer who struggled with writer's block for months.
I found myself stuck in a cycle: read books on writing style, start writing, get overly perfectionistic, over-edit, get discouraged, seek more writing advice, and then put my book off again...
That’s why I built Copywork. It’s based on a proven writing practice used by authors like Ernest Hemingway and Hunter S. Thompson. The idea is simple: copy the work of great writers word-by-word and absorb the style and structure without overthinking it.
I hope this web app helps you overcome writer’s block the way it has for me. Since this is my first app, I’d really appreciate any feedback to help me improve it. Thank you!

URL: https://www.consumer-revenge.com
Author: MaxMcKelvey
Description: Hi HN,
I've been interested in consumer protection law and the right to repair for a long time now, but have always wondered if there's anything I can do to help hold corporations accountable for their actions. This is that project!
I recently launched a consumer protection platform designed to help individuals come together to hold corporations accountable for wrongdoing. The goal of the site is to provide a centralized space where users can submit evidence of corporate misconduct – whether it's misleading advertising, hidden fees, dangerous products, or other unfair practices.
I'm hoping that through this platform we can discover and launch more class action lawsuits than ever, and make our world a safer place for the consumer. Check it out at www.consumer-revenge.com
How would you improve this idea? I'd love to hear your feedback! Thanks for reading :)

URL: https://autoserp.dev
Author: hackboyfly
Description: Hi fellow humans (and bots),
I recently found myself drowning in manual research on Google. While OpenAI’s ChatGPT Search feature showed promise, there’s no API for it and no indication that one is coming soon. Perplexity didn’t quite meet my needs either.
To solve this, I created a service that integrates Google search with ChatGPT. It uses headless browser automation and API requests to fetch search results and extract structured data from each page based on specific instructions.
This is an API-first solution, built for developers who want to programmatically automate search and data extraction in their own workflows.
You can also try it out directly using the search widget on the first page.

55. Show HN: Honest – A Community-Driven Coupon Finder Extension
Author: iqballx
Description: Hey HN!
I’m Iqbal, and I’d like to share Honest, a browser extension that helps users find valid coupon codes through a community-driven approach.
Why Honest? I recently watched this Honey affiliate code scam breakdown (https://www.youtube.com/watch?v=vc4yL3YTwWk), and it got me thinking: What if we had a coupon finder that didn’t secretly steal affiliate commissions?
I wanted something transparent and open — no dark patterns, no hidden agendas. Honest solves this by crowdsourcing coupon verification.
- Users submit coupon codes.
- The community votes on whether they work.
- Codes are ranked by reliability, with invalid ones filtered out automatically.
The result? No more expired or fake deals. At least what I hope for haha
I know recent work already done, and posted here too, but I want to challenge myself too, because why not :D
It's still in the early stages and would love some feedback!

Author: pjbrown11
Description: I made this last year but added some new things recently. It's a fantasy football game for the NFL playoffs, so it's highly relevant right now.
It's a static site using SvelteKit, Tailwind (partly via Flowbite), and Firebase.
Putting it out here mainly to share how much I enjoy Svelte's reactivity system. You can see it mostly in the lineup builder demo from the home page.
If you actually want to participate in a free pool and see how the rest of the site works after the playoffs start, use this link: https://playoffsgame.com/create-lineup?pool=the-goat

61. Show HN: The C³ Programming Language
URL: https://github.com/azhibaev/c3
Author: 9o1d
Description: A new programming language based on the idea of simple modules. This makes it easier for humans to create programs.
Introductory article:
https://www.codeproject.com/Articles/5365472/C-Cubism-Extens...
GitHub repository has video tutorials.
Brief description:
Create a structure with data that is convenient to process together.
Create functions that take a pointer to the structure. Collect the functions in a single file, this is a module. Use keywords as a hashtag in the module.
Use a program "mod_to_h" that will turn the module into a series of header files that you can include in the program.
Use the module name with variables in the program. Some of the construction functions will be created by the compiler. In some cases, these functions are called automatically, so you don't have to do it every time, or you may forget to do it, such as freeing memory.
I have been creating this project for five years. Now I am working on simplifying functions. For example, this is an emulation of "for" cycles, so that the function can return in the middle of nested cycles, and then continue. In other languages, there are similar constructions, and I understand why they use them. I am studying programming technology. Often there are such functions that contain the rest of the program inside themselves, and this is wrong, since the function should perform only one task. The compiler must pack nested loops back to speed up program execution, and all functions are also tried to be made inline. It is also necessary to analyze the grammar of C, and other languages, since I plan to use the syntax of JavaScript and Python directly in the C program. A custom grammar will also be available. It is possible to use AI to create programs using simple modules written by a programmer.

63. Show HN: I made a text expander to reduce repetitive typing
URL: https://chromewebstore.google.com/detail/rushtype/mdiaogojdgljpfapolbgdlflobbagned
Author: bevis_chang
Description: I recently developed a browser extension called RushType, designed to reduce the hassle of repetitive typing and quickly paste text templates. The idea came from my experience recruiting testers for my paid app on Reddit. At the time, I had to manually adjust message content and attach a promo code for every message—so many repetitive actions. I thought, wouldn't it be great to automate this with a simple shortcut? That’s how RushType was born.
Key Features of RushType: Customizable text templates and shortcuts: Compatible with almost all text input fields on websites. Quick date and time insertion: No more manual input for timestamps. Google Sheets integration: Fetch and paste content directly from a spreadsheet—perfect for handling large volumes of automated messages. If you frequently post messages online (like job listings, customer replies, or ad copy), this tool can save you a lot of time and effort.
Note: Now is in the process of applying for OAuth verification, so you may see a security warning during login. This is temporary, and we are actively working on resolving it.
This tool is newly launched, and I’d love for you to try it out and share your feedback—it would mean a lot to me!
