AURA Declarative, down to the details
Components, anchors, layouts and typed properties. A small language for clearly structured interfaces.
The language ↗NATIVE UI FRAMEWORK
Application UI Runtime Architecture
Interfaces.
In your hands.
A clear language for your UI. The full control of C++. AURA brings declarative interfaces to a native runtime — from your first widget to a complete kiosk.

The building blocks
From the first idea
to the final pixel.
Layout, interaction and runtime work together. You describe the interface; AURA connects the pieces.
Native graphics. Directly.
Skia for text, vectors and images. Plus video, Rive animations and optional WebViews.
Graphics & rendering ↗State that connects everything
Bindings keep your interface current. Records, lists and states give your data structure.
State & bindings ↗See what you are building
Live preview in VS Code, dynamic loading and window-free PNG rendering.
aura-view ↗A runtime for your application
Tasks, timers, processes, data formats and devices. C++ building blocks even without graphics.
The application side ↗Built to connect
HTTP and TLS, remote control, and JavaScript and Lua behind one shared API.
Framework overview ↗TARGET PLATFORMS
Native at the terminal.
Available in the browser.
Linux is the native reference platform. The WebAssembly port brings the shared UI runtime to the browser. The porting status of other systems is documented clearly.
Linux
Native reference platform for desktops, touch terminals and kiosks. SDL3 connects available display and input backends.
Browser
The real AURA runtime in a canvas: Hello, gallery and editable playground. Operating-system services have specific limits.
Windows / macOS
Skia packages and graphics build paths exist. A complete platform port with system services and tests is still outstanding.
The framework in action
Real widgets. Real possibilities.
Screenshots from aura-demo, rendered directly with AURA. Eight pages bring the framework to life.

The architecture
Your UI is declarative.
Your application stays C++.
One .aura file, two execution paths: typed C++ code at build time, dynamic loading during development. Context, state and signals connect them.

Proven libraries. Clear origins.
Skia, SDL3 and other native building blocks power AURA. Explore the selected versions, their licenses and optional modules.
The development flow
Less distance between
your code and your interface.
Describe
Components, layouts and states in .aura. Readable, typed and close to your interface.
Connect
C++ provides data and handles signals. Small UI reactions can use JavaScript or Lua.
Refine
Save, inspect the preview and keep working. Generate C++ for the production build.
