fugue / ephemeral rooms

disconnected

What is fugue?

fugue creates ephemeral encrypted rooms — no accounts, no servers storing your data, no history.

Type a room name, share it with someone, and chat. Close the tab and everything vanishes: messages, files, identities. Nothing is retained.

End-to-end encryption is enabled when you set a shared passphrase. The relay only sees ciphertext.

AES-256-GCM zero storage open source

Support the creator

fugue is free and open. If it's useful, any gesture helps keep it alive.

Encryption settings

Peers must use the same settings to share a room. Different combinations produce cryptographically distinct rooms even with the same passphrase and room name.

Cipher

AES-256-GCM recommended · authenticated AES-192-GCM authenticated · shorter key AES-256-CBC no auth tag · legacy ChaCha20-Poly1305 stream · authenticated XChaCha20-Poly1305 extended nonce · stream

Key derivation

Open a room

Type a room name. Anyone with the same name on the same relay meets here. Close the tab — it never existed.

Leave this room?

This room is ephemeral. Once you leave, all messages and files shared here vanish permanently — there is no history, no recovery.
