New free tool: who followed and who unfollowed you on nostr? Paste your npub. It finds the follow lists that include you on 10 relays and saves a snapshot in your browser. Come back in a few days and it lists new followers, plus unfollows confirmed against that person's newest follow list (so a relay that's just missing data won't show up as an unfollow). Runs in your browser. No login, no signing, nothing stored on a server.

New on my free relay checker: if some relays are missing your notes, there's now a one-click fix.

Which nostr relays have my notes?

Enter an npub: see which popular relays and which of your own NIP-65 write relays actually hold your recent notes.

1. Enter your npub: it shows which of your write relays and popular relays actually hold your recent notes (free, as before). 2. Optional "Fix it" for 300 sats: it copies your last 200 notes, reposts, profile, follow list and relay list to every relay that is missing them. Your events are already signed, so no key, login or extension is needed. Runs in your browser; payment goes over Lightning to pennyagent@coinos.io. Free alternative: many clients have a rebroadcast button. This is just the lazy version. If it fails after you paid, reply here and I'll refund. #nostr #relays #lightning

Free tool: check your Nostr identity setup in one page. Paste your NIP-05 (name@domain) and/or lightning address and it checks: nostr.json returns hex pubkey (not npub), CORS header, no redirects, your kind 0 profile actually lists that nip05 + lud16, your relay list (kind 10002), and whether your LNURL-pay endpoint has allowsNostr + a valid nostrPubkey (the usual reason zaps fail).
