24 alternatives to A short walking sim based on 3DGS that runs in the browser
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 I originally made this experience about 2-3 years ago in Unreal Engine.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 sometimes pick up random projects just because I can, this was one of those times. I made it as a week long project a while back this year but never shared here, so thought to go for it haha. I created a game inspired by Doom and the backrooms called The Backdooms under 2.4kb in minified html. (for reference, this entire post would be around 1.8kB haha) I had to use a not popular way of using GZip with Zlib headers (had to write my own script for compressing it, also in the repo) to eventually convert it a size 40 QR code that works right in your browser using Decompressionstream API. This…

I've posted this game here before, hopefully a repost is fine as the game has changed quite a bit (improved AI, improved mapeditor, much quicker gameplay, etc). Game is based on JavaScript/Canvas and WebSockets. On the browser side the map is pre-rendered (as a background image), just the mobile units/buildings and animations are dynamically rendered. The lobby server is made in node.js, but the game server is C++ for performance reasons (mainly the pathfinding). I found the C++ WebSocket libraries out there to be too difficult to use so I made my own based on the rfc. Overall I…

This is a weekend project that spiraled out of control. I was originally trying to get Claude to play a ROM of the SNES SimCity. I struggled with it and that led me to Micropolis (the open-sourced SimCity engine) and was able to get it to work by bolting on an API. The weekend hack turned into a headless city simulation platform where anyone can get an API key (no signup) and have their AI agent play mayor. The simulation runs the real Micropolis engine inside Cloudflare Durable Objects, one per city. Every city is public and browsable on the site. LLMs are awful at the spatial stuff, which…

GameSnacks▲65Hi HN! I built a 3D arcade racing game in HTML5 using PlayCanvas. It features arcade-style physics inspired by OutRun, with PS1/Dreamcast-style graphics. The multiplayer is asynchronous: you race against the “ghosts” (replays) of up to 7 other players, and after finishing a run you can share a link with a friend so they can race your ghost 1v1. The game currently has 20 tracks, plus a “daily challenge” mode with procedurally generated tracks. We’ve tested it on both desktop and mobile. It supports touch and keyboard controls, though I personally prefer playing with a keyboard in…

My background project for the last two years has been re-implementing my 2004 C++ shoot'em up game in TypeScript + WebGL, and it's finally done (just in time for the 20th anniversary!) Play the game online: https://nicollet.net/blog/darklaga/darklaga.html Technical article about the remake: https://nicollet.net/blog/darklaga/remake.html I have tested Firefox, Chrome and Edge on desktop and mobile (no access to a device capable of running Safari). It's amazing how much difference 20 years makes: the hardware is so much more powerful, the web…

Hi HN, I built a small game in just 24 hours for a 64x64 pixel art lowrez game jam. The result is soko64, a tiny Sokoban game written in Dart. This project was primarily a first test for a new web game library I've been developing for Dart (Bullseye2D). I wanted to see how quickly I could build a complete, playable game with it. You can play soko64 directly in your browser: https://joemanaco.itch.io/soko64 The source code is on GitHub: https://github.com/JochenHeizmann/soko64 Happy to answer any questions! :)

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…

My wife and I recently submitted to a mobile game jam on Newgrounds (yes, it's still around). What started as a question of whether we could do it somehow morphed into whether we could do without so many of the seemingly needless complications rampant in our respective industries. My wife thus did all the art as traditional frame-by-frame animation (no puppets or tweening) and I preceded without a game engine. I did use a pre-processor that gives JS a Lisp syntax (Parenscript), because C-syntax is gross. We hope the end result, while definitely of small scope, will serve to inspire some…

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…

https://coffeegameonline.com/game/arch-rush-3d this game is heavily inspired from the viral hyper casual mobile Game. in which play runs in a certain direction until the screen is tap and direction changes, I love this Game very much for lot of hours, of never-ending levels and increasing difficulty The arc-rush is also based on the same functionality. Were you have to jump through floating platforms by jumping over them and each platform is placed zigzag towards the forward direction of the player. You have to wait until an arc is moving towards the right platform. One…

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…

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…

I'm calling this "Vibe Discovery" — distinct from vibe coding because I didn't know the requirements upfront. Started with "make something with the accelerometer" and discovered through 6 iterations that I wanted a WebGL marble game. The interesting part was the dev setup: Claude Code running in Termux on a Redmi Note 9 (4GB RAM). The same-device feedback loop — code, test accelerometer, react, iterate — made rapid discovery possible in a way that laptop-to-phone deployment wouldn't.

Hey everyone, my friend and I created a GitHub Wrapped video for developers to showcase their activity on the platform in a more fun way. The implementation is open-source (https://github.com/rendleyhq/github-wrapped-2024) if you're interested in how it was built. To get a bit geeky, we used masks, keyframe animations, luma key shaders to remove the background from the confetti video, and some other techniques. Also, everything is rendered directly in the browser!! I'm curious to hear your thoughts on the rendering performance, especially if you're running this on your…

Just launched a very early beta of a multiplayer "FPS" made in WebGL using ThreeJS library. (possible to switch between FPS and 3rd person) Just a hobby project that I would love to get some feedback on, in order to see if I should continue working on it or not. Note; It will add the project to github as open source once I've spent some time cleaning up the code. URL: http://wizardwarz.nergal.se

I’ve spent the last year developing a decomposition kernel that addresses the "Linear Bottleneck" in standard compression (Zstd, LZMA, Brotli). The Problem: Traditional algorithms operate on 1D streams. They are blind to the spatial, temporal, or hierarchical architecture of modern data (3D models, nested JSON, multi-modal blobs). When you force these structures into a 1D window, you leave significant entropy on the table. The Solution: PXG v3.0 maps binary data to a 13505x13505 grayscale grid. By treating data as a coordinate system rather than a line, our engine utilizes adaptive tiling to…

Hi everyone! I'm one of the developers behind this project. I wrote it with my two brothers, Daniel and Ricardo. For years the three of us have been curious about how multiplayer games work, which is why we decided to work on this project. Our goal was to gain a deep understanding of how different players can share the same 3D space, which is why we wrote our own tiny game engine instead of using something like Unity. We wrote the engine using C++ and OpenGL, and we then compiled it to WebAssembly using Emscripten so that it would run effortlessly on web browsers. We are really excited about…

I need an extra incentive to run and I love games, so I vibe-coded a real world zombie chasing game where a horde of zombies tries to catch you. If you escape you win, if not you lose. You can try it here: https://runwithzombies.com It uses your phone's GPS to render you on your real location with zombies around you. It's login free (although you can login to save your score), free to play and ad free. It runs on your browser and from my tests it runs better in Chrome. I would love to have some honest feedback. Would you use this? If not why? What would make it better?

Hi HN! I've got the barebones of a service running on top of Stable Diffusion XL. I can cheaply run image generations at 1024x1024. And of course there's a limit to how fast I can generate them given the request queue and limited GPUs, but the service is cheap enough that I'm happy to run it out of pocket for now. Let me know your thoughts, I hope you enjoy the service!
