Siteplane UI

Source-owned React UI primitives for calm, dense SaaS and dashboard products.

Siteplane UI is a free React component system built on Base UI, Tailwind CSS and source distribution.

It focuses on animated fundamentals: everyday controls and product patterns that feel finished through subtle, centralized motion instead of one-off effects.

What belongs here

  • Public usage guidance for installing and composing Siteplane UI.
  • Source-of-truth documentation for registry distribution, providers, motion and foundations.
  • Component API pages that are stable enough for consumers.

Review environment

The UI Lab remains an internal review and playground surface for deep previews, polish queues, motion experiments and temporary comparison work.

Public docs describe accepted behavior and source contracts. They do not depend on UI Lab routes or unfinished review notes.
