3d.city is an open-source, browser-based 3D city building game rendered with Three.js via WebGL2 or WebGPU. It uses the micropolisJS simulation engine running in a Web Worker to keep rendering smooth while simulating city growth.
Use cases
- play a 3d city builder in the browser without installing anything
- build and simulate a city like simcity in a web tab
- explore an open-source city building game
- study how to combine three.js rendering with a web worker simulation
- try a webgpu-powered 3d game demo
When to choose
- you want a free, no-install city building game playable in any modern browser
- you want to inspect or fork an open-source 3d city simulator built on three.js and micropolisJS
- you want a lightweight webgl2/webgpu gaming demo
When to avoid
- you need a full-featured commercial city builder with deep mechanics and save/load polish
- you need a native desktop or mobile game
- you require guaranteed stability — the project is a long-term work in progress with an active roadmap
