Alternatives
Products that do what WASM Cloth Simulator does
I wrote this a few months ago over Winter break. It's the fastest/highest fidelity browser cloth sim I've found, but this codepen (1) is close. I'd love to hear any insights about cloth simulators / spring constraint solvers 1: https://codepen.io/dissimulate/pen/nYQrNP GitHub: https://github.com/mkhan45/clothsim

Hey HN, I'm Mehul, founder of codedamn. I'm glad to release codedamn creator (https://creator.codedamn.com/) in public beta today - the first (and only?) interactive course creating platform available to create truly interactive programming courses. Unlike existing solutions of embedding iframes from different code execution services, we have built the whole system from the ground up - allowing the course students to work inside a powerful in-browser editor solving code challenges. This will enable you to create highly interactive courses on virtually any topic. Want to teach…

I made an open-source Python library for the Stable Diffusion Web UI. It's a direct alternative to Huggingface Diffusers except it has more features + runs the same scripts as A1111 so the results are replicable. Please give it a star on Github! https://github.com/saketh12/Auto1111SDK

Hi HN, After watching a lot of Show HN's here, it's finally my turn to show something. This is the first real project I have shipped, so it is extra special to me. For those who will inevitably ask why I made yet another mockup editor I covered it on our blog (http://blog.mocktailsapp.in/why-build-yet-another-mockup-editor-tm). Not all the features mentioned in that post have been implemented yet. As such Mocktails is pre-beta software and very minimal. It does not even have user accounts or any actual server side component at all for that matter (yet)! Our intention is to build Mocktails…

Hey HN! I wanted to practice "vibe coding" and see how far and fast I can go by only prompting, without actual coding. I decided to make a simple CLI app that scrapes web docs into a single md file (I was annoyed that LLM keeps writing Tailwind 3 code for a Tailwind 4 project). In just a couple of hours, the CLI app was ready! Then iterated on arguments for another couple of hours. Result: https://github.com/vladstudio/web2llm Then I decided to go further and "productize" the CLI by making a web app for it. Another half-day, and the web app is ready!…

Hey HN, 4 days ago I went through the impressive demo of IDM-VTON on HuggingFace. I found there was no ComfyUI adaptation of this new model. So I’ve implemented custom nodes in ComfyUI that allow anyone to perform virtual try-ons using IDM-VTON. Simply load an image of a model and a garment, and the node will generate a new image with the garment worn by the model. I would love to hear your thoughts and feedback! Cheers, Tom

Hi HN! I've never posted anything on here before, but this project was too fun to pass up. I've been learning a lot about agents lately, and wanted to see if I could replicate some of the results of Windsurf and Cursor. Generally I love these tools, but when you're stuck behind an "enterprise" firewall, they don't work as well. This sad state of affairs motivated me to understand SWE agents more. Does it work? Yes. Is it as good as Cursor and Windsurf? Not quite, but it's pretty darn close, depending on the model you use. I'm lacking a few features like semantic indexing, MCP support, but…

I recently made this game Doge Decimator with the websim team, and wanted to make a process video for the steps I took to make it in an AI-native platform! You can check out every single iteration the site went through from the links in the description :)

Hi HN, While building RAG agents, I noticed a lot of token budget was wasted on formatting overhead (HTML tags, JSON structure, whitespace). Existing solutions felt too heavy (often requiring torch/transformers), so I wrote this lightweight, zero-dependency library to solve it. It includes strategies for context packing, PII redaction, and tool output compression. Benchmarks show it can save ~15% of tokens with negligible latency overhead (<0.5ms). Happy to answer any questions!

Hi all, I threw together a small prototype I am calling “Notepad.ai”. A new take on UIs for interacting with LLMs. While I enjoy using LLM’s in the chat format I wanted to see what it would be like to do it in a more long form style. It let’s you write in a pretty free form, much like Window’s Notepad, but you can choose to hit ctrl+[ to analyze the text with a preset prompt of your choosing. It has a few other small features. It’s WIP and very experimental. I would appreciate any feedback or thoughts. Video: https://youtu.be/ntdlgFmSxQY Live Demo:…

Hi HN! This is my first game — something I’ve always wanted to do. It’s a small browser game built with Phaser 3, React, and the phaser template (https://github.com/phaserjs/template-react-ts/). I made it in 2 days (like 8 hours in total real time) using gemini-cli. About 90% of the code was generated with AI, but I learned a lot by making fine tweaks. It only works on PC since it’s a typical WASD + R (reload) shooter. I’d love feedback on: - Gameplay (is it fun, too hard?) - Ideas for new features Thanks in advance! ps: I used cubes as a prototype, but now I kind of…

Hey HN! I develop browser extensions, I suck at web design, and I've been exploring AI/LLMs. With my new found free-time since dropping work hours, I've developed a Design Copilot browser extension [0]. It does what it says on the tin - you choose a part of your website and the tool gives you instant expert design feedback - "change this font to that, add this much whitespace, use brighter colours .... etc" The tool is completely 100% free to use, its powered by bringing your own AI API Key, and the current LLM it uses is Google Gemini 1.5 Pro. I've yet to hit the free rate-limit and I…

Hi! I built a free short walking sim you that runs in the browser. I originally made this experience about 2-3 years ago in Unreal Engine. The resulting build was huge: over 6 GB to download in order to play for max 10 minutes. Needless to say there weren't that many people that ended up playing the game. Seeing the quality that's possible to achieve nowadays in the browser using gaussian splats, I recently got the idea to port it to a web-based experience. The result is that the whole game is a bit over 100 MB, and that's including about 20 MB of music and VO. Thanks to Spark's streamed LOD…

I was randomly browsing claude codes ralph wiggum plugin[1] and was surprised to see my toy project referenced. Since it appears people are getting some value out of it, thought I'd share it here... Full disclosure, this repo itself was built with a primitive ralph wiggum loop so expect AI slop. It works though. ¯\_(ツ)_/¯ https://mikeyobrien.github.io/ralph-orchestrator/ [1] https://github.com/anthropics/claude-code/tree/main/plugins/...

Hello everyone, A couple of months ago I was introduced to Excalidraw and fell in love with it instantly. The only thing I didn't like was that I couldn't easily save my whiteboards and had to put everything in one whiteboard which started to lag my PC after a while. So I made ExcaliHub. It's exactly as it sounds: a hub for Excalidraw. It's free, open source, and I aim to keep it that way. Thanks in advance for any feedback!

Hey guys, I made a VS Code extension, within which you can use the Mixtral 8x7B AI model for free. Mixtral 8x7B is a new AI model from the Mistral family, which outperforms GPT-3 in many benchmarks, a fact that I have personally confirmed in daily coding tasks, where Mistral 8x7B was the clear winner. You can use all the AI features, such as AI Lens with custom instructions and similar. I'm pretty sure some of features will be useful to you. I'd appreciate both, positive and negative feedback!

Hey HN, it's Vineeth from Plastic Labs (https://plasticlabs.ai) and we built this demo/game to showcase the latent capabilities of language models to simulate identities. We wrote more about what it is and how to use it on our blog (https://blog.plasticlabs.ai/blog/YouSim;-Explore-The-Multive...), but I'll try to quickly summarize. We took heavy inspiration from projects like WorldSim, WebSim, and Infinite Backrooms and prompted Claude Opus to act like a CLI interface that can simulate these identities while another instance will interact with the CLI. To…

Over the past three months, I’ve been working with my dad on this app as a way to learn Cursor, shadcn/ui, and Next.js. I’m currently studying UX design at the University of Michigan, and I’ve been really impressed by how much vibe-coding tools have advanced over the last six months. This work journal includes private AI-generated insights with scheduled summaries that can be shared with your team or manager. You can also choose to make a summary public—like I’ve done here for my work on this web app: https://www.workjourney.ai/summary/mkblt2zt-hn2kdbus If anyone has…

It took me about a week to vibe code this 3D game engine with Opus 4.6 that I intend to use as a replacement for Three.js and React Three Fiber in my browser MMORPG, Mana Blade. I was not expecting to be able to reach that point so easily, but pretty much every feature took somewhere between 30 minutes and 1 hour - 1 to 3 prompts on average. It is vibe-coded in the sense that I haven't looked at the code, but I am very careful with my prompts and constantly have Claude reviewing the codebase, looking for performance and code quality improvements. It can reach 2000 draw calls on recent…

Hi there, looking for feedback on my new project "Featherless.AI" The idea is to allow users to run all the models on hugging face instantly. Via the OpenAI API compatible endpoint. Why? Because its a real chore to download models and spin up GPUs, especially if you want to test multiple models. Not to mention GPUs cost multiple dollars an hour to rent. And if we want more people to use open source AI, we got to make it easier for them to try and play with all of them. So what if instead of spinning up dedicated GPUs per model (which is what every provider is doing) We can startup a LLM…

After fine-tuning GPT for a personal project, I realized how tedious it is to write plain text in a massive JSON file. That's why I built this app for my own use, and I want to see if others could benefit from a tool like this as well ;)

I’ve spent the last few days prototyping a browser-based game engine stack designed for instant-load, "Roblox-for-Teens" style deployment. The goal is to lower the floor for AA indie devs who want high-fidelity physics and instant web distribution without the overhead of Unity or a heavy Godot export. The Stack Engine: A headless WASM/WebGPU implementation. I’m currently using custom flags and selective streaming to bypass standard browser memory and execution limits. Physics: I’ve ported Jolt (Guerrilla Games) but modified the solver to mimic the original Blam! engine (Bungie/Halo…

This started as a "cyberdeck" style crafts project using ESP32-S3, for some retro coding. Then I got carried away and wrote a self-hosted mini C compiler for it. Now I published the whole system that runs it. The core reusable parts are also packaged in Espressif Components Registry as "BreezyBox". So far, this platform lives up to my dreams: instant on, snappy when optimized, flexible with resource allocation. I upgraded to a bigger screeen: Waveshare ESP32-S3-Touch-LCD-7B, 7", 1024x600. It takes some effort to drive it with good speed on the S3, but this sort of challenge is exactly why I…

Hi HN, Our research team just released the best performing and most efficient reranker out there, and it's available now as an open weight model on HuggingFace. Reranker v2 was designed specifically for agentic RAG, supports instruction following (our v1 was the first to introduce this), and is multilingual. Along with this, we're also open source our eval set, which allows you to reproduce our benchmark results. By releasing these datasets, we are also advancing instruction-following reranking evaluation, where high-quality benchmarks are currently limited. Please give it a try and let us…
