Changelog
New components, blocks, and docs improvements.
November 2026
- Saved: press S or click Save on any component or block page, and find everything again on one page with live previews and one install command for the free items. Signed in, the list follows you to every device.
- A faster library sidebar: every group in one list you can fold, search by what you are building and not only by name, and a short description when you rest on a row.

Launch
Docs
- Every component and block page now has installation with CLI and manual tabs, usage, an API reference, keyboard, accessibility, and motion notes.
- Search the library with / or ⌘ K, filter the sidebar by Free or Pro, and read the new Installation, Theming, and Motion guides.
- Close block variants share one page with a variant switcher: sidebars, login, onboarding, team, settings, pricing, checkout, analytics, AI chat, inbox and support, scheduling, project views, and feature sections. Old links still work.
Registry and AI
- Install by name with the
@uiarcregistry namespace. - An MCP server,
llms.txt, and a Markdown version of every page. See AI and MCP.
