Cogent Core is a free, open-source Go framework for building fast, elegant 2D and 3D apps that run on macOS, Windows, Linux, iOS, Android, and the web from a single codebase. It provides a widget-based GUI toolkit with WebGPU/Vulkan-backed rendering and compiles to WebAssembly for web deployment.
Use cases
- build cross-platform desktop apps in go
- write a gui app that runs on mobile and desktop with one codebase
- compile a go gui app to the web with wasm
- build 3d graphics applications in go
- create native ios and android apps from go
- make a cross-platform 2d app with a widget toolkit
When to choose
- you want a single Go codebase targeting desktop, mobile, and web
- you need GPU-accelerated 2D/3D rendering via WebGPU/Vulkan
- you prefer a widget-based toolkit with interactive documentation
When to avoid
- you need a mature ecosystem with a large widget and third-party library selection
- your team does not use Go
- you need pixel-perfect native platform UI conventions on each OS
