Installing WebberUI
WebberUI is a shadcn registry. You need a project with components.json — run npx shadcn@latest init first if you do not have one. Tailwind CSS v4 is assumed.
1. Direct URL (no setup)
Works immediately. 288 of the 395 components are free and need no credentials.
npx shadcn@latest add https://webberui.com/r/split-text.json2. Namespace (shorter, needs one-time config)
Add the registry to components.json, then reference components by short name. Without this entry the CLI fails with Unknown registry "@webberui".
{
"registries": {
"@webberui": "https://webberui.com/r/{name}.json"
}
}npx shadcn@latest add @webberui/split-text3. Pro items (107 components + 104 templates)
Pro items return 401 without credentials. Pass a license key as a Bearer token — the CLI expands ${WEBBERUI_KEY} from your environment, so the key itself never enters version control.
{
"registries": {
"@webberui": {
"url": "https://webberui.com/r/{name}.json",
"headers": { "Authorization": "Bearer ${WEBBERUI_KEY}" }
}
}
}Signed in on the site, you can also copy a ready-to-run command with a short-lived token from any component page — see the setup guide and pricing.
4. Machine-readable index
Every item, with a meta.tier of free or pro. Useful for directories, tooling and AI agents.
https://webberui.com/r/registry.en.json # 499 items, English titles and descriptions
https://webberui.com/llms-en.txt # llmstxt.org site index, EnglishTitles and descriptions in that index are English. The component source is a separate matter: comments inside the .tsx files are still being translated, so most components install with Traditional Chinese comments for now. Component names, props and the code itself are English throughout.
5. AI coding agents (MCP)
There is an MCP server that lets Claude Code, Cursor and Codex search components and fetch source without a components.json existing yet. Note that shadcn CLI 4.13+ ships its own MCP server which is more complete if you already have one — details in the MCP guide.
