UI Patterns
A UI pattern library built for coding agents. 40 patterns, each shipping a copy-paste prompt that rebuilds it inside your own codebase — plus a live preview and the source behind it.
Every pattern, three ways
Preview
The pattern running live in an isolated frame, in whichever theme you are reading in.
Source
Its markup, styles and behaviour, plus a single runnable file carrying its own palette.
Prompt
A written spec that rebuilds the pattern from scratch — including why each decision is the way it is. Paste it into Claude Code, Cursor, or any coding agent.
The prompts are the point. Each one is written to survive being handed to an agent with no other context: it names the surfaces the pattern belongs on, spells out the constraint that makes it work, and calls out the failure it exists to prevent. Nothing here is a dependency you install.
