"nostr" stands for "Notes and Other Stuff Transmitted by Relays" and is an open protocol for censorship-resistant global networks created by @fiatjaf.

- expensive relay - a relay that requires payment for registration
- me.untethr.nostr-relay - a relay written in Clojure
- Minds Nostr Relay - a relay for Minds, an open-source social network
- Minds Engine - Nostr - relevant Minds API code for reading/writing Minds posts using Nostr
