24 alternatives to I vibe-coded a custom WebGPU engine for my MMO

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…

    It was quite interesting to vibe code this artifact. I learned some basic ideas about commitment scheme and hash cryptography in the half and hour spent on this. One of the few times vibe coding left me feeling enriched rather than drained. What do you think?

    Hi! I took a cheap $25 walmart phone and put a static server on it? Why? Just for a fun weekend project. I used Claude Code for most of the setup. I had a blast. It's running termux, andronix, nginx, cloudflared and even a prometheus node exporter. Here's the site: https://walmartphone.stetsonblake.com/

    I know vibe coding is controversial. I wanted to give it a try so over the last ~4 weeks I tried vibe coding a blender/houdini inspired node based 3d geneartion app in my spare time. The original goal was to try to generate great looking 3d environments from relatively small data. Most games download megs or gigs of data and that's no good for web based things. If you're an AI skeptic still, maybe seeing more concretely what's possible today might convince you otherwise? I'm not making any claim the code is good, though I'm also not claiming is bad. I had fun giving it a try. I was…

    Hi HN! Lifelong avid gamer here, hugely passionate about WASM and WebGPU. I firmly believe that these technologies will enable console and PC quality titles to be accessible through a browser, and with this, we'll need a new discoverability layer. Looking online, platforms like CrazyGames and Poki cater to a casual/hypercasual demographic, and I couldn't find anything out there that was for me, a core gamer that typically uses Steam and consoles. So I vibe coded my own! It features WASM ports of classic games, as well as some indie Unity titles. The goal is to host mainly WebGPU titles…

    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…

    Hi everyone, I just saw a vibe coded game on HN, and thought maybe I should post about this here. I'm organizing a vibe coding game dev competition called Vibe Jam. Last year we did it too and there was 1000+ games submitted. This year the deadline is May 1 and you can submit your games until then. There's $35,000 in prizes with the Gold prize being $20,000. Let me know what you think! -Pieter

    I've been using Cursor, Co-Pilot, ChatGPT, Claude and what not since quite some time now, and we are at a stage where we can just "vibe code" whole apps from idea to execution in a few prompts. I tried this personally to create some side projects that solved little problems for me. But I always got stuck at a point where it just goes into an infinite loop of issues and can't solve the issue by itself. Well I'm a developer, so it's easier for me to dive into the code and solve the problem myself, but that would take a hell lot of time to understand all the code AI wrote for me. If I keep…

    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.

    I'm the developer. Happy to share the process and learnings. Architecture: - Custom SoA ECS for cache-friendly iteration, zero allocations in hot loops. Benchmarked against bitECS/miniplex. - Process manager inspired by Game Code Complete's but data-oriented so processes are pure data, systems contain the logic. - Multi-field gravity with 5 types (point, parallel, segment, cylinder, convex hull) with spring-damped transitions between fields. - Rapier3D WASM with SIMD. Gravity-aware fake shadow system for playability. - WebGL 2 shared context between Three.js and Pixi.js. - Debug editor…

    Hey HN! I am building Vibeloop, a platform where you write small programs — canvas animations, GLSL shaders, Phaser games, charts — and they show up as discoverable cards. https://vibeloop.app The card types are: - Canvas — JS with a setup()/draw() loop - Shader — GLSL fragment shaders - Phaser — full Phaser 3 games in a card - Chart — powered by Chart.js - Markdown — with LaTeX math Some things I think are interesting: - Cards can use audio (Web Audio API beep/noise synthesis), mouse/touch input, uploaded images as textures - A watchdog kills runaway code (infinite…

    Fully leaned into vibe coding this time around. Started on v0, at some point ejected into running locally (getting v0's exported folder to run locally was a challenge), then iterated with Cursor over the course of a few hours. Really neat how much can be accomplished just conversationally these days.

    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!…

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.

    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…

    VibeSolve is an open-source tool that turns a plain-English description of an optimisation problem into Timefold code. Mathematical optimisation is a branch of mathematics and computer science that searches for the minimum/maximum of objective functions, and has applications in transport, logistics, scheduling etc. We are exploring where LLMs can add value in optimisation algorithm development, and where they get in the way. Right now, it works well for rapid prototyping. It does not create production-ready code and requires technical skills to use. It is noticeably better at creating…

    Hi HN! Solo developer here. 10 days ago, I started building this after spending countless hours copying/pasting marketing sections and fighting to keep them consistent with our design system.

Current progress (10 days in): - Can generate hero sections that follow your design tokens - Uses your actual component variants and styles - Works with Next.js, Tailwind, shadcn/ui It's very early days, but I'm excited to share it with other devs who: - Are tired of rebuilding…

    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…
