You pick which layers your app depends on.

You pick which layers your app depends on.How do I add it to a Rust project?Add gpui-kit as a Cargo dependency; by default it pulls in GPUI, gpui-base, gpui-component, and the bundled Lucide icon set, and you can turn off default features to keep only the layers you actually use.

Yes, this is built directly on GPUI, so you need working Rust/Cargo knowledge and familiarity with GPUI's elements, entities, async model, focus, and actions.Can I replace the bundled icon set with my own?Yes, leave the default assets feature out and name your own SVG files to match the identifiers defined in IconName instead of using the bundled Lucide set.
Yes, leave the default assets feature out and name your own SVG files to match the identifiers defined in IconName instead of using the bundled Lucide set.Which AI coding agents have official skills for this?GPUI Kit ships installable skills for Cursor, Claude Code, Gemini CLI, and Codex, covering setup, the component catalog, GPUI mechanics, and the design guides.
GPUI Kit ships installable skills for Cursor, Claude Code, Gemini CLI, and Codex, covering setup, the component catalog, GPUI mechanics, and the design guides.Has this framework been proven in a real product?Yes, GPUI Kit has powered Longbridge Pro, a shipped commercial desktop trading app, from day one, so it was extracted from real production needs rather than designed in isolation.
