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

- NNostr - a C# relay
- nostr-rs-relay - a minimalistic relay written in Rust that saves data on SQLite
- Relayer Basic - a simple relay based on relayer backed by Postgres
- nodestr - a Node.js implementation
- 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
- NostrPostr Relay - a Kotlin Relay supporting both SQLite and Postgresql
- nostrypy - relay, client and other tooling in python
