about
- description
- Staircase is a private group messenger built on [Cordn](https://cordn.net): end-to-end encrypted MLS groups (RFC 9420) whose messages are ordered by a coordinator you choose and carried over Nostr relays. No phone number, no account on anyone's server, and nobody in the middle can read along. - **Group chats** with replies, reactions, @mentions, pins and encrypted photos and files - **You decide who's in**: admins, invite links and QR codes; members join with their own Nostr key - **Your keys**: a local key or Amber (NIP-55); nothing leaves the device unencrypted - **Multi-device**: link your phone and desktop to the same groups - **Open network**: pick your coordinators, relays and Blossom servers - Works with other Cordn clients such as cordn-web; also available for Linux desktop (deb, rpm, Arch)
