Pricing

It is free

BlockDex is free to use. There is no account, no trial and no paid tier. Nothing on this site is behind a payment, and no part of it asks for a card.

What the free covers

• The whole index. Every item in every public shadcn registry, searchable at the item level, with the install command printed on the row.
• The whole API. No key, no account, CORS open to everyone. Every screen on this site makes exactly one call, and those are the calls anyone else can make.
• The CLI namespace. The index is searchable and installable from inside the shadcn CLI, and the install resolves to the registry’s own endpoint rather than to anything here.
• The badge. A registry can put this index’s measurement of it on its own page, free and with no account, and neither it nor we can set the value by hand.

The API in full, and how the index is built.

What there is not

• No account, no sign-in and no password. There is nothing to steal and nothing to reset.
• No sponsorships, no submissions and no hand-placed entries anywhere on this site. There is no way to buy a position.
• No rate limit on the read API beyond the edge cache. Please cache responses: the index is rebuilt once a night, so anything polling faster spends requests for nothing.
• No quality score and no rating. A crawler cannot establish whether a component is well built, and this one does not pretend to.

Free to install is not the same as free to use

The crawl checks whether a registry serves an item’s source without credentials, not what its licence permits. The licence shown on a registry’s page here is the string its GitHub repository declares, and where it states none the page says so. That is a question for the registry rather than for us, and it is worth reading before shipping something commercial.
