Noscl

noscl is a command-line client for Nostr, the decentralized social protocol. It does what a graphical client does, but from a terminal: publish notes, read your feed, follow people, manage your profile metadata, and send encrypted direct messages.

Nostr identity is a keypair rather than an account, which suits a tool like this. You set your private key once and every command signs with it — no login, no session, and no server holding your account, just a key and the relays you publish to and read from.

The command-line form pays off in scripting. Because publishing a note is a single command, anything on your node that can run one can post to Nostr: a cron job, a monitoring alert, a script that announces something when a condition is met. It pairs naturally with Nostr RS Relay if you would rather publish through a relay of your own.
