awesome-nostr

"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.

Relays

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

Implementations

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)
nostr_relay – a nostr relay written in python, backed by SQLite

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.
nvote - it does server side processing, and even private key is handled server side, and as such is deprecated for normal use.
alphaama.com - is under maintenance as of late 2022.
