PixilUI and ReUI
A shadcn registry by Keenthemes: 27 primitives and 1,264 free component examples, 672 Pro blocks including agent operations screens, every primitive in Base UI and Radix UI versions, and a hosted MCP server.
In short
ReUI sells dense operator screens for running agents: a fleet overview, a run queue, step traces, an approval inbox, tool access and evaluation reports, plus the Flux agent console template with Ultimate. Choose ReUI for the console a team uses to run agents. Choose PixilUI for the moments inside your product where an agent asks or works, each item listing its states, keys and reduced-motion behavior.

What ReUI is good at
- Operator consoles for agents: fleet overview, run queue, a failed run's step trace, approval inbox, tool access, playbooks and nightly evaluation reports.
- Flux, a Next.js agent console template with run queues, step traces, human approvals, a tool matrix, eval regressions and token spend.
- Every primitive in Base UI and Radix UI, a free Figma kit, and agent notes with when to use and when not to on every block's markdown page.
- A hosted MCP server and an agent skill.
What PixilUI adds
- The moments inside the product rather than the console: an approval card that folds into a receipt, a run timeline with a waiting step, a tool call row with a live timer.
- Items wired to your callbacks: an approve callback that returns a promise shows its own pending and success states.
- Free items over MCP with no account, and a 14-day refund before any Pro source is installed.

Questions
ReUI or PixilUI for agent UI?
ReUI if you are building the operations side: a console where a team watches runs, approves work, sets tool access and reads evals. PixilUI if the agent is inside your product and you need the moments a user sees, each with its states and keys listed. Many teams need both.
Can ReUI and PixilUI share a project?
Yes. Both install with the shadcn CLI and both offer Base UI. ReUI reads shadcn/ui theme tokens and PixilUI reads its own foundation.css, so keep one library per surface.
Do both work with Claude Code and Cursor?
Yes. ReUI has a hosted MCP server and an agent skill; a free account signs in on first connect. PixilUI publishes llms.txt, an agent skill and a remote MCP server that serves free items without a login.
