GoKawiilAdi2
A modern GUI library for Ada.
Adi2 gives you a real widget toolkit with the niceties developers expect from a modern UI stack — CSS-like styling with live reload, declarative XML layouts, animations, SVG and Lottie graphics, internationalization, and asset bundling — implemented natively in Ada on top of SDL3.
Status: in production use, but not yet a stable release — APIs may still change between versions.
Why Adi2?
Style your UI like the web. Selectors, pseudo-classes, parts, transitions, gradients, box shadows — all in a familiar .css syntax. Edit the file, save, see the change. No recompile during development. Prefer pure Ada? CSS rules are just plain Ada aggregates of Style_Rules — write them by hand with no extra ceremony (see the snippet below).

CSS rules are just plain Ada aggregates of — write them by hand with no extra ceremony (see the snippet below). Describe UIs declaratively — or don't. Write <button> , <grid> , <text-editor> in XML and let the toolchain emit clean Ada packages, or construct the same widget tree directly in Ada with handle-based builders. Both paths target the exact same API; the XML generator is a convenience, not a requirement.

A built-in lightweight HTML view widget renders documentation-style markup with cascading styles. Raster images through SDL3_image, SVG through the bundled plutosvg, Lottie animations through bundled rlottie.

Bundle every CSS file, font, image, translation, and SVG sprite into your executable. No filesystem dependencies at runtime.
