24 alternatives to Vibe-coded Steam, but in the browser

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! I made many small web games in the past with Unity or Phaser. But this time I wanted to make something completely on my own. So I coded a basic game framework in plain JavaScript, and used it to make Almost Pong. This was a really fun project that taught me a lot about JavaScript, and I plan to make more minimalist games with this framework. Interesting fact: Almost Pong doesn't load any assets, all sprites and sounds are generated with code. Happy to answer questions, and please let me know if you have any feedback on the game. Thanks!

    Hey all, creator of Video.js and co-founder of Mux & Zencoder here. My team and I built this. I hope you like the themes we’ve built so far, and maybe even get inspired to build your own. I know Web Components are in a bit of a drama cycle right now. I’m happy to see them get any attention really. I’ve been pretty bullish on them since ~2013 when I started working with them, at least in the context of a widget like a video player. I’ve even given many related talks on them like this one (https://www.youtube.com/watch?v=N6Mh84SRoDg). I would never push them for a large app or…

    Earlier this year, we released our open-source game engine [0] built with Rust, WebAssembly, and WebGPU. Today, we’re happy to announce the Ambient platform, which brings web deployment, server hosting, and more to the runtime. With Ambient, you can make a game, deploy it to the browser in one command, share your URL and instantly play with others, no downloads or installs needed. Our WASM use is innovative; it is being used as both a sandboxed runtime for user code, and as a way to run the entire Ambient runtime in the browser. This, paired with our ECS data model, enables a highly modular…

    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 been working on an MMORPG that is now in alpha as a solo developer. Here are the major open source technologies that I use: Blender - 3D modeling software for creating the overall environment and every game object. I've gotten a lot of CC and Public Domain assets from https://poly.pizza GLTF - I export assets from blender to the GLTF asset format JSON - I write a JSON config for every game object that describes things like its name, its interactions, its collisions, etc. Node.js exporter - I iterate over the environment and every asset to create a scene hierarchy. I use…

    I'm making a platform for simple open source games you can play anywhere. Games are all just JavaScript classes and you can read the source of every game on the platform. I started working on initial "games" (mostly rendering tests) in 2018 and eventually built all of the platform stuff around it to make it easy to share games. There's also an in-browser editor available for you to make and publish games all from the browser. Would love some feedback on the games and studio features as well as the platform overall. All of the code is available at https://github.com/homegamesio

    Hey HN, This is my take on the agent harness. Everything on an isometric map. Agents are grouped into "buildings" that run in a sequence or a loop; e.g., the CodeForge has an agent that writes a PRD, another one that implements, and a third that reviews. Everything is customizable, you build your own buildings/teams however you want. It's a Tauri app, really light (about 8x less energy than the closest competitor I benchmarked, so it actually runs from a coffee shop on battery). It's macOS only for now, but ping me if you are willing to test the Windows or Linux version. I've been…

    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…

    Hi 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…

    Hi HN! made a vibe coding platform with the non-technical user in mind. This means that you don’t have to integrate Supabase, Auth0, it’s automatic. Our goal is to soon also provide email, payments, and other integrations automatically. We target SMB owners and entrepreneurs. We will differentiate by talking non-technical, hide code most of the time, friendly consumery UX and support Made pricing also simpler: 1 credit = 1 prompt (drives me nuts when in other platforms you don’t know what you’re paying for) Would love any thoughts!

    Hey HN! Been working on this emulator on and off for the last couple years, and thought now would be a good time to try and show it off here. As far as unique features... I think this is the only online GameBoy emulator with support for save files? So there's your reason to exist, I guess. The WASM port was something I had in the back of my mind but I just kept putting it off because it seemed like it would've been a pain in the ass to implement, but all in all I think it took less than a week so that was a nice surprise!

    It took me 20 months to develop it in my spare time. I used Unity game engine, I did not have any game dev experience before. It was more complex that I thought at the begining, I spent lots of time on promotion, marketing, founding company, learning about the legal aspects of different parts, for example music. Some parts were easier than I expected. Unity makes it very easy to build for all three operating systems (Win, MacOs, Linux), I am not sure why more game devs are not using this possibility. I also like working on Steam as distribution system. It is not exactly easy for a newcomer,…

    So, me (dev) and my friend (designer) have been building a website/mobile app to help users manage their game library (think MyAnimeList, but games) for a little over a year. We launched with a very basic set of features, and have been slowing expanding since then. All the code is open source, and most of the things we implemented were direct feedback from users (e.g. being able to import games from Steam/PSN, and the Posts feature). We don't show ads or have any kind of subscription. This is just a hobby project. Any feedback would be greatly appreciated, as honestly the hardest…

    A WebAssembly runtime embedded in Godot game engine projects. Interact with Wasm modules from GDScript. Accessing Wasm modules via GDScript provides the following benefits. - Sandboxed environment allows safely loading zero-trust mods/extensions to a project. - Single target means that Wasm modules can be built from any language e.g. Rust, Go, AssemblyScript and the single binary can be run on all platforms. - Fast execution compared to GDScript allows for offloading compute-heavy operations or running bots/mods/etc. at high FPS. This might be useful for loading mods, bot AI,…

    This was an interesting porting project for a few reasons (IMO): - The original game is/was awesome and, from a programming perspective, a wonder -- smooth scrolling arcade game on a 128kb Mac in 1984... - The port was done with a lot of help from AI (mostly Claude Code, but some Gemini CLI as well). I'm a programmer; it wasn't vibe-coded. But I couldn't have done the port of 68k assembly without it. FWIW, Claude seemed better at actually porting the 68k assembly but Gemini was better at finding bugs. YMMV. - I love Redux and Redux Toolkit for state management. For the port, I put the…

    Hello Hacker News! I’ve been working on a side project that ports the entire Source Engine to run in the browser using Emscripten. (Yes, the same engine that powered Half-Life 2, Portal, CSGO, and more.) It’s still a work-in-progress some features are missing and the launcher is in development but core engine functionality is up and running. I’d love feedback, ideas, or contributions.

    Hey HN i’m a platform engineer and my day job I mainly focus on kubernetes clusters and terraform with the occasional C#, Typescript when building services, so this could well be completely out of my depth. Jolt started as an experiment to see whether I could build my own network at all. I’ll also be honest that most of this code was agentically written. However the high level decisions and architecture were mine based on research, experimentation, trial and error. Canary testing was one of the consequences of that when you build this way you need something slapping your AI-driven confidence…

    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…
