# BlockDex

> Item-level search across every public shadcn registry. Find the component, not the library, with its install command, its dependencies, whether it is free, and whether it still exists.

https://blockdex.thecompound.tech

## What this is

Item-level search across every public shadcn registry. Other directories list registries; this
one indexes the components inside them. Every row is derived from a manifest a registry actually
served — there are no submissions, no sponsorships, no editorial list and no hand-edited rows.

Free to use. No account. Open API, CORS open to everyone, no key.

## The index right now

- Items indexed: 76,062
- Registries crawled: 994
- Free to install (verified by fetching the item endpoint): 34,092
- Behind a paywall (endpoint answered 401): 11,081
- Components: 39,331 · Blocks: 26,235 · Hooks: 854
- Items whose own source we hold: 24,633
- Items with a live preview the registry permits framing: 19,586
- Last rebuilt: 2026-09-16

## How free-vs-paid is decided

The crawler fetches each registry's item endpoint — the exact URL `npx shadcn@latest add` would
fetch. Source back means free. A 401 means paid. A registry that serves no probeable item
endpoint has its items marked unverified, never free. Several registries are mixed: a public,
browsable manifest with the item endpoints gated, which is invisible until you try to install.

## How removals are handled

An item missing from a manifest that parsed is definitively gone — the registry served its
inventory and the component was not on it. It is marked removed with a date and its page stays
up saying so. A registry that fails to answer for three consecutive days is marked gone.

## What this index does not do

- No quality, design or accessibility judgement. A crawler cannot establish any of that.
- No submissions and no corrections by request. A hand-editable row makes every other row
  unverifiable.
- No mirroring. Install commands point at each registry's own endpoints.
- No licence interpretation. The licence shown is the one the GitHub repository declares; free
  to install is not the same as free to use commercially.
