24 alternatives to A tutorial series on building multiplayer (.io) web games
I have some experience building these kinds of games, so last year I put together a beginner's guide on them. It's been getting more attention recently with people wanting to make/experiment with these games during quarantine, so I figured I'd share to get feedback: - Part 1, Client: https://victorzhou.com/blog/build-an-io-game-part-1/ - Part 2, Server: https://victorzhou.com/blog/build-an-io-game-part-2/ - [demo] An example .io game: https://example-io-game.victorzhou.com/
Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. A tutorial series on building multiplayer (.io) web games launched in 2020; newer entries below may have overtaken it.

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 wasn't quite sure if this qualified as "Show HN" given you can't really download it and try it out. However, dang said[0]: > If it's hardware or something that's not so easy to try out over the internet, find a different way to show how it actually works—a video, for example, or a detailed post with photos. Hopefully I did that? Additionally, I've put code and a detailed guide for the netboot computer management setup on GitHub: https://github.com/kentonv/lanparty Anyway, if this shouldn't have been Show HN, I apologize!

Hi, I've been developing an HTML5 MMORPG game where people can submit code to play a game, like collect items, destroy defense towers or kill monsters, etc.. I've been working on this for over 1.5 yrs (all my spare time) and now it's ready for preview, does anyone want to try it out? It's mostly opensource (and the rest will be opensource sooner or later) Please access it with PC, it's an HTML5 game: https://bytelegend.com/ I really want it to expand to more languages, but right now I've only finished Java part. I wonder if anyone can help me with other languages. Besides, I'm…

Hi HN community! We want to share AI-town, a deployable starter kit for building and customizing your own version of AI simulation - a virtual town where AI characters live, chat and socialize. Inspired by great work from the Stanford Generative Agent paper (https://arxiv.org/abs/2304.03442). A few features: - Includes a convex.dev backed server-side game engine that handles global state - Multiplayer ready. Deployment ready - 100% Typescript - Easily customizable. You can fork it, change character memories, add new sprites/tiles and you have a custom AI simulation…

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'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

hi all, I've always wanted to make my own game, but couldn't afford a thousand-dollar adobe (flash+photoshop) license. I'm not a talented programmer, have no degree in CS. But I understand some elements of design. So I got me a copy of ImpactJS, and after about 5 months of steep learning curve (at least for me), I managed to come up with a game. I also integrated it with a highscore and badge system, similar to what you get at Kongregate. You need to login with Google/OpenID to earn badges/scores. link is: http://www.hotbazooka.com/privatejoe hope to hear some feedback/questions from you guys!

Hey folks — here’s a small experiment I hacked together over the weekend: https://cleoselene.com/ In short, it’s a way to build multiplayer games with no client-side game logic. Everything is rendered on the server, and the game itself is written as simple Lua scripts. I built this to explore a few gamedev ideas I’ve been thinking about while working on Abstra: - Writing multiplayer games as if they were single-player (no client/server complexity) - Streaming game primitives instead of pixels, which should be much lighter - Server-side rendering makes cheating basically…

I know everyone is a bit burned out on blockchain and cryptocurrency related stuff around these parts, but I've been working on as a side project for the last few months and thought you guys might be interested: https://cryptoempire.io/ It's still a bit buggy and incomplete (the mobile ux needs a lot of work, the leaderboard isn't functional yet, etc.), but I've reached a point where I'm not totally ashamed of sharing it :) Any feedback would be most welcome!

Link: http://xoxo.cm The idea here was to build a multiplayer game with the lowest possible barrier to entry to get started. That is, no registration, no game setup, as few steps as possible to actually start playing. There's not much substance here right now and there's still a few bugs that need to be hammered out. I'm also thinking of expanding on the idea with some other simple games down the road. Any feedback or suggestions on the concept in general would be much appreciated.

Hello HN. This is a project me and some friends built at university in 2017. It was originally built in a rush, but we've added a few improvements over the years. It's a fun game to host at a demoparty and project on a big screen - We did that at Instanssi many times. The implementation is still rough, and suffers from the fast pace of the modern web - The frontend is likely very outdated, and the backend is built with Vapor 2 and Swift 3.1, both no longer supported. You can host this yourself, but it might be a bit of a pain to set up. The WebSocket protocol is fairly trivial to work out…

Hey HN, I made https://linkians.com which is a game where all the action and state is contained in the url. The game involves taking care of little pets (emojis) that live in your url bar. Kind of like tamagotchi or sims. Feed them, play with them, and watch out for enemies! There's no server, just emojis in the url and client-side logic. Any linkians url using the supported emojis is a valid game state so you can save your game, or type out your own url and send it to a friend. I'd appreciate any feedback.

Hey all, just wanted to share a little game experiment. It's a rooms & keys kind of adventure with a lot of random deaths. It plays a Veo3-generated video in response to clicks, with Gemini used for coding. Prompting the videos was fun, but trying to vibe code everything was not. In the future I'll go back to using LLMs more sparingly for isolated functions, or at least try not to have it create anything that requires seeing the output to debug.

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…

Hi HN, I'm one of the engine programmers at All Out Games (https://allout.game/), a multiplayer-first gaming UGC platform where creators can make and play games with their friends. For scripting we wanted our creators to be able to jump in and create game mechanics without having to think about networking. If a developer had to manually send packets to/from client/server to get things to happen then we have failed. It is particularly bad if you are using AI tools because they struggle to keep in mind what code is meant to run where (client, server, or both) and…
