Bits UI
Build a Svelte component system from flexible primitives with behaviour already supplied.
What’s included for free?
Bits UI's headless component source is free under MIT. Components are intentionally unstyled, so you supply visual design, integration and application-level accessibility checks. This is reusable developer software, not a hosted builder. Your application code, deployment, infrastructure and any external services remain separate.
Where it runs: Local install
