Elara- A free open-source coding game built with Rust and WebAssembly
I'm excited to share a project that I've been working on mostly solo for the past year! It's called Elara, and it's a free open source game that teaches you how to code. You can play directly in your browser without downloading anything or creating an account. It's targeted toward complete beginners, but if you already have some coding experience, there are optional bonus challenges to really test your knowledge and problem-solving skills. If you like code golf, some of the challenges will be right up your alley ;) Under the hood, the backend/core game logic is built with Rust and…
What it does
In the maker’s words, at launch
I'm excited to share a project that I've been working on mostly solo for the past year! It's called Elara, and it's a free open source game that teaches you how to code. You can play directly in your browser without downloading anything or creating an account. It's targeted toward complete beginners, but if you already have some coding experience, there are optional bonus challenges to really test your knowledge and problem-solving skills. If you like code golf, some of the challenges will be right up your alley ;) Under the hood, the backend/core game logic is built with Rust and compiled to WebAssembly, and the frontend/UI is in TypeScript and React. In-game, you write code in Rhai, a scripting language tightly integrated with Rust. I chose this architecture for a few reasons: it offers good performance for compiling and running user code, has important sandboxing/safety guarantees like preventing infinite loops, and means the entire game can run in-browser without the need for any servers (aside from just serving static files). Keeping costs low was really important since the game is 100% free and I would like to keep it that way. Check it out and let me know what you think! I'll be checking back here periodically to answer any questions. The full source code is available on GitHub: https://github.com/albrow/elara.

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!
- ISI spent 6 years making a cool free game2015 · ▲151
Hey everyone! Long time lurker, first time poster. I've just reached beta in my game BoxByte Lyte. -What is it- It's a free 3d arcade game for hardcore players that uses color matching in interesting ways. Also it's a one button game, well movement and one button. Cool huh? The final release will be free too. -What I need- This is a very challenging game, so I really need to balance the difficulty so that it's still hard but not impossible. It would be great just to hear your experiences of the game and how far in it you got. -Where can I report bugs?-…
- MAMaginet, a cross-platform strategy game with Rust/WebAssembly2023 · evrim.zone · ▲8
I hereby present my little tiny pet project that entertained me for the past six months. In this post, I briefly present Maginet and its technical components. It is a turn-based strategy game that is built using Rust and compiles to WebAssembly with HTML5 bindings, which works on mobile and desktop alike! It comes with many game mechanics and components, including an AI opponent and online cross-platform multiplayer. There is so much to discuss even for a project of a smaller scale, but I am nevertheless excited to share a little bit about how you can actually build a game in Rust,…
- CACoderoulette, a pair programming game for developers2016 · ▲42
Hello everyone, We just launched a side-project we have been building over the last couple of months -- Coderoulette is a pair programming game for developers, like a Chatroulette for hackers. We match developers in real time and give them coding challenges they have to solve doing pair programming using a collaborative IDE and video conference. You can check it out here: https://www.coderoulette.com/ We also published an article explaining how we built it. I'd love to hear your feedback.…
- AMA multiplayer game to discover NFT artists, built with WebAssembly2022 · play.moonlightmuseum.io · ▲9
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…
- MBMy biggest solo-project: Game engine with its own programming languageMay 2026 · github.com · ▲5
Hi, so i'm making a 2D game engine with its own IDE and interpreted programming language, all are written in C# It's open source, and I'm looking for contributors! The backend engine is MonoGame, the IDE is WinForms and the project is real, not just another AI-slop... Please check it out, i promise it's an unusual thing! Here's a YouTube video showing me using the engine for making a little cute game: https://youtu.be/h_AnUg4yJWs?si=MR3nQCVvOMDP3iqg Any feedback is welcome!
