awesome-nostr/README.md

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

Protocol

• nostr - overview and FAQ
• NIPs - the "Nostr Implementation Possibilities" describe the protocol in technical detail
• nostr, a basic tour - an intro to nostr
• Nostr: Solucionando la censura de una vez por todas
• UseNostr - A small guide for anyone who wants to learn more about how nostr works and what it can do.
• nostr.how - Quick-start to onboard desktop users with Alby & Astral

Relays

Relays are (so far) application agnostic. You can run your own or use any or all of the public instances.

Implementations

• 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
• nostream - a nostr relay written in Typescript backed by PostgreSQL (renamed from nostr-ts-relay)

Deprecated

• anigma.io - has known xss attack vulnerabilities, which can put private key at risk, or risk signing events you may not want to send.
