Capy is a declarative cross-platform GUI library for Zig that renders native controls using each target OS's toolkit (win32, Cocoa, GTK, Web). It supports cross-compilation from any platform to any other and exports a C API usable from other languages.

Use cases

build a desktop app in zig with native controls
one codebase for windows linux and web uis
small native gui executables without electron
cross-compile a gui app from linux to windows
accessible native ui toolkit for zig
embed a native gui in a zig application

When to choose

you write in Zig and want native look-and-feel per platform
you need tiny binaries and no runtime/VM overhead
accessibility and OS-native keyboard/IME support matter
you want seamless cross-compilation of UI apps

When to avoid

you need a production-ready, API-stable toolkit - breaking changes are ongoing
you need macOS or Android today (work in progress) or iOS (planned)
you want to embed UI inside a game or custom rendering pipeline (explicit non-goal)
your team doesn't use Zig and the C API is insufficient
