NIP-05 checker
Validate a name@domain Nostr identifier end-to-end:
URL format, HTTPS, redirects, CORS headers, JSON shape, pubkey
format, advertised relays. Real npub bech32 output.
Free tools
Public, no-signup utilities for debugging Nostr and Lightning identifiers. We never store anything you paste here.
LNURL decoder
Decode any LNURL bech32 string, lightning address, or LNURL URL,
then fetch and pretty-print the response: payRequest,
withdrawRequest, login,
channelRequest.
Nostr key generator
Generate a fresh Nostr keypair (priv/pub hex, nsec,
npub, nprofile) entirely in your
browser. Optional vanity-prefix search via Web Worker. Nothing
is sent or stored.
