Rendering
Skia rendering with Vulkan, OpenGL, Metal, and software backends. GPU support and fallback depend on the platform.
Async runtime
Spawn tasks tied to a component, a window, or the whole app. Integrate Tokio when you need it.
State & caching
Reactive state, shared stores, and async queries with caching and invalidation through Freya Query and Radio.
Routing
Typed routes, nested views, and navigation history, without putting everything in one component.
Multi-window & tray
Open more windows, share state between them, and keep desktop actions in the system tray.
Terminal
Embed a terminal with PTY support, keyboard and mouse input, and clipboard integration.
HTML & Markdown
Render HTML and CSS with Blitz, or display Markdown documents inside your app.
Camera & video
Capture webcam frames or play video with audio using optional media integrations.
Components & animation
Buttons, inputs, calendars, virtual lists, and more. Animate sizes, positions, and colors.
Text & code editing
Text selection, cursor control, rich editing, and a code editor with tree-sitter highlighting.
Testing & devtools
Test interactions headlessly. Inspect the component tree, layout, and performance as you build.
Docs & examples
API references, guides, and runnable examples, from a counter to multi-window apps.
AI-ready
Give your coding assistant the Freya skill or llms.txt so it can work with the right APIs.
Charts & plotting
Build charts, graphs, and interactive data visualizations with the Plotters integration.
Icons
Use Lucide icons in your components, with control over their size and color.
Internationalization
Translate your app with Fluent and switch languages while it is running.
Accessibility
AccessKit integration, accessible roles and labels, keyboard navigation, and focus management.
Theming
Share colors and typography across components, create custom themes, and switch them at runtime.
Shaders & custom drawing
Write Skia shaders, draw on the canvas, and add gradients, shadows, and blur to your UI.
Docking & resizable panels
Build tabbed workspaces with dockable panels, split layouts, and draggable resize handles.
Drag & drop
Move typed data between drag sources and drop targets, or handle files dropped into your app.
Material Design
Add Material Design components and effects, including ripples, to your app.

Built-in components
Buttons, sliders, calendars, color pickers, and virtual lists. Try them in the gallery.
Animations
Animate colors, sizes, and positions with control over timing, easing, and sequences.
Rich text editing
Selection, keyboard shortcuts, formatting, and virtualization for more than a basic input field.
Code editor
Rope-based text editing and tree-sitter syntax highlighting in a reusable component.
Charts & plotting
Draw charts and interactive visualizations with the Plotters integration.
Terminal emulation
A terminal inside your app, with PTY support for shells and command-line tools.
Developer tools
Inspect the component tree and its properties while your app is running.
