Products that do what Cozy Quest – MMO networking architecture does
I'm building a cozy multiplayer game engine (very early stages - just a few days in!) combining Elixir, Go, and Godot to achieve sub-50ms latency while maintaining a warm, welcoming feel. My architecture uses Elixir/Phoenix for fault-tolerant session management, Go for high-performance game state sync (1ms tick rate), and Godot for client-side prediction. I've implemented lock-free data structures, SIMD-optimized physics, and binary protocols with delta compression. Quick note: the website/login aren't functional yet - this is a work in progress! Here's my technical deep-dive into…

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…

Modd.io is a collaborative game editor that runs in browser. It's kind of like Figma for game dev. We made this engine low-code and multiplayer-first, so developeres can quickly prototype casual multiplayer games. I hope some of you guys will find this useful. Would love to hear feedback also. Thank you. Engine Demo: https://www.modd.io

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…

I made a game (https://polyfight.io/) which revolves around a player (a tank) leveling up and upgrading by killing shapes and other tanks (partially inspired by https://diep.io). It has a bunch of features, a vast number of tanks, an inbuilt chatting system, clans to make teams with your friends, a colour scheme maker, controllable sandboxes which can be public or private, a last man standing gamemode, and an inbuilt 1v1 system with its own ELO rankings and a global leaderboard. The game has a few players right now, and I'd hope to spread the joy players have with…

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…

A few months ago (82 days to be exact!) I posted a link on HN to my game, Meatshields. A bunch of you commented and played my game and gave me some wonderful feedback. Over the last few months I've been playing with many of you and implementing the best of everybody's suggestions. So, thank you, HN for all your help! I feel this is an extreme overhaul I couldn't have done without your input. Since then, I have: Dramatically improved our hosting platform (So it HOPEFULLY won't go down this time (oops.)), Added two new units, Rebalanced all existing units, Added many more maps, Improved the…

I've been writing Elixir for 5 years and made plenty of sites with Phoenix and LiveView but my biggest gripe has always been with the lack of quality UI components available. The JS ecosystem has so many, and it's the one thing I miss from being primarily a React & Node developer. So this is my attempt at bringing some pretty and useful components most applications need to Phoenix projects to try and fill in the gaps between what makes LiveView such a productive joy to work with. The library is very very raw and requires some initial clean up so PRs are very welcome to tidy up the DX as well…

This is based on an approach I made for a very high performance message and video multiplexing server. The project died, but I'm glad I get to share the a basic version with some http test code now. I admit this is the second time I've tried to show this off here today; I posted earlier but it got lost when no-one was watching :(

Around three years ago, I was reminiscing about how much I loved playing Neopets as a kid. Meanwhile, I was also looking for a project to better learn Rust and SolidJS. So.. I figured making my own virtual pet browser game would be a fun way to practice! Since then, I’ve been working on it nearly every day, and.. it’s grown quite a bit! Here are some bulleted lists for your convenience: Technical Details: * Backend monolithic Rust server runs on a single $5/month VPS * Lean frontend with just 3 dependencies (SolidJS, Solid Router, and Mutative) * Around 130,000 combined lines of code…

Hello everyone! I've finally finished my latest side project - a RPG game made in Blazor. It started as a small project to learn some Blazor (I'm .NET dev but kept mainly to backend and ASP.NET). I had such a good time coding it that at some point I decided to make a full featured game out of it. I might've have bitten off more that I could chew as RPGs have so many systems and elements but overall I think it worked out well, especially for a single person project. I want to hop on the next project soon so any comments/questions/tips than can make me better really appreciated!

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 HN! This has been a fun little side project. You simply click to shoot arrows at falling circles (and the arrows of other players!) Hopefully, I make other social & simple games over time. I had to struggle with all the usually problems of game synchronization. It was a fun way to explore phoenix & elixir. You'll notice the signature claude code purple gradient. I'll be honest, I couldn't have built it without AI! If you really like it you can vote with your wallet and toss me $1.99. Or not!!

For the past few months, I’ve been hacking together Hive: a retro-style virtual workspace for devs who love building in public. It’s a bit rough but already has some cool features: - AI-powered presence to represent you when you’re offline. - Live video streaming to showcase your work in real time. - VS Code integration to broadcast your status live. - GraphQL API for full customization and hackability (such as using your own agents) - Web3 donations to support and get support from other builders. In this demo, you can claim a desk by walking up to it and pressing E, then personalize it with…

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…

Hi HN, I’m one of the devs behind StarDesk, a P2P-first remote desktop we’ve been building for ~1 year. We started this partly out of frustration: some popular RDP tools haven’t seen meaningful updates in a long time, and long-standing issues are often left unaddressed. As devs, we really dislike software that stagnates once it “works well enough”. StarDesk is our attempt to do it differently. What we focus on: -P2P by default (relay as fallback) -Low RTT + low jitter > chasing max bitrate -Encoder / input path tuned for real-time interaction -Modern E2EE (TLS/DTLS) UX-wise, setup…

About a month ago, I shared the Day 1 prototype of this project (https://news.ycombinator.com/item?id=46448670). It has since evolved into a somewhat more polished "Slot-Machine Deckbuilder." I also recently moved the project from qq-pwn.com to alt-qq.com. I did this mid-development specifically to see if I could migrate a live player base and session states without losing people. The Design Challenge: The core of the game is a "One-Armed Bandit" dungeon crawler. The challenge is balancing the "house always wins" nature of slots with the player agency required for a good…

I'm working on the Survival Crafting RPG that you would have played on your Apple II back in the '80s. You can think of it as Valheim's gameplay crammed into the tile-based UI of the old Ultima games. It has a procedurally-generated open world with towns and NPCs to talk to, all the resource gathering, mining, crafting stuff you'd expect in a modern survival game, and some good old fashioned dungeon crawling to boot. I've been working on it off and on for the last several months. It's complete up through the Bronze Age (in Valheim terms). Let me know what you think!…

Over the past few months, as we scaled our internal AI Agents, we hit a dead end: Running LLM-generated arbitrary code in Docker is basically running naked on security due to container escape risks. But using full traditional VMs takes minutes to boot and eats too much memory to support high-density concurrency. We loved the developer experience of SaaS sandboxes on the market, but they are closed-source, expensive, and have too high a barrier to entry for self-hosting. So, our team decided to build our own. After months of grinding, using RustVMM and KVM, we built a blazing-fast,…

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…
