Declarative views. Render on demand.

A Go GUI framework for Windows, macOS, and Linux. Declarative views meet retained updates in an event-driven runtime, with CGO-free builds, multiple windows, and typed components, layouts, and themes.

Run your first window

Explore components

Declarative API, retained core
Describe the UI with immutable Views and let the framework reconcile the tree. Stable keys retain focus and editing state while your application owns its data.
Understand views and state
Event-driven updates
Windows share an event loop while keeping independent UI and interaction state. Idle windows do not repaint continuously, and paint-only changes avoid unnecessary layout measurement.
Explore runtime behavior
Build without CGO
Build the framework and applications with CGO_ENABLED=0, using familiar Go modules and compilation workflows for each desktop platform.
Run and build
Typed layouts and themes
Configure layout, appearance, and interaction states with concrete Go types. Primitive, Semantic, and Component tokens provide consistent customization with validated theme updates.
Explore styles and themes
Virtualized long lists
Fixed-height VirtualList mounts only visible and overscan rows. Stable keys and scroll anchoring keep large datasets manageable.
Use virtual lists
Icons linked on demand
Choose from 2,066 official icon names and aliases with theme colors and configurable stroke widths. Reference only the constructors you need so the Go linker can discard unused icons.
Use icon resources
