Nosterm
Nostr with an IRC soul.
Nosterm is a browser-based Nostr client that looks and behaves like a classic IRC command-line terminal. It connects directly to relays over WebSockets — no custom backend — and is driven entirely by IRC-style slash commands.
Old-school chat. New-world protocol.
The interface is pure IRC muscle memory — channels, nicks, /-commands, a
scrolling log. Underneath, it's Nostr: an open, decentralized network of relays with no
central owner. Familiar on the surface, unstoppable underneath.
⌘Command-driven
Drive everything with familiar IRC-style slash commands — /join,
/msg, /nick, /theme. Tab completion included.
⚡No backend
A client-only SPA that talks straight to Nostr relays over WebSockets. Your data path is you and the relays — nothing in between.
🔐Keys stay yours
Sign in with a NIP-07 extension, a remote signer (NIP-46), an nsec, or a freshly generated key. No third-party analytics, ever.
#NIP-29 rooms
Join relay-scoped managed groups with real rosters, invites, and moderation — the IRC channel model, on Nostr.
🌐Federated
Channels can span multiple relays run by different operators — mirror chat across peers so a room outlives any single relay. No single point of failure.
🎨Themeable
Twelve built-in terminal themes — Nord, Gruvbox, Dracula, Tokyo Night, Solarized and
more — switchable live with /theme.
✉Private DMs
End-to-end encrypted direct messages via NIP-17 gift wrapping. Send with a single
/msg.
Channels without servers. Identity without passwords.
Rooms are NIP-29 managed groups that live on relays, not on a company's servers — spin one up anywhere, or run your own relay in the bundled Docker stack. Channels can even federate across relays run by different operators, so a room outlives any single one. And you never register: your identity is a key pair you already control, so there's nothing to sign up for and no password to leak.

Chat without surrendering your identity.
No tracking, no third-party analytics, no remote scripts — the client only ever talks to the relays you choose. Your private key signs your messages and nothing else, and with a browser extension or remote signer it never even touches the page.
