guidoA native UI runtime for any language

Build desktop apps in Bun, Python, Rust, Go, C, Zig or Nim. Your code talks to a 21 MB runtime that renders real windows and widgets.

Get started

What is guido?

Installs as a package

npm install godot-ui-sdk or pip install godot-ui-sdk includes the runtime. connect() finds it without configuration. A tarball covers other languages.

Logic stays in your language

The runtime renders the UI and reports events. Application code, dependencies and tooling stay in the language you already use.

Visual UI design is optional

Lay out screens in the Godot editor and drive them by node name, or create every widget from code. Both are supported.

Small runtime

One 21 MB binary (8 MB compressed) instead of a bundled browser. Apps start in under a second and can ship as a single file.
