> Nostrord is a free, open-source NIP-29 client for decentralized group chat on Nostr. It brings a Discord-style experience to a censorship-resistant protocol, with relay-enforced moderation, cryptographic identity, and no sign-up required.
## What is Nostrord?
Nostrord is a Kotlin Multiplatform (KMP) group messaging client built on NIP-29, the Nostr specification for relay-based groups. Users create or join groups hosted on any NIP-29-compatible relay, with membership, moderation, and permissions enforced by the relay itself rather than a central server.
Your account is a cryptographic keypair you own. There is no phone number, email, or username tied to a central service. The same identity works across every Nostr app.
Current release: v2.10.1
## Key Features
- NIP-29 relay-based groups (create, join, manage)
- Channels inside a group: a single-level hierarchy of kind:39000 groups linked by non-standard `parent`/`child` tags, with a sidebar tree, admin-gated creation and drag-and-drop ordering. Only shown on relays that advertise `nip29.subgroups` in their NIP-11 document, so it is unavailable on most public NIP-29 relays
- Threads: forum-style discussions on NIP-22 kind:1111 comments, with a split view on desktop
- Group admin tooling: invite codes, join requests review, member promotion and removal, group metadata editing
- Chat, replies (kind:9 with a `q` tag, the NIP-C7 convention, not NIP-10 markers), and message deletion
- Moderation: admin roles, member management, relay-enforced membership and permissions, user mute (NIP-51) synced across devices via NIP-78
- Encrypted direct messages: NIP-17 gift wrap with NIP-44, user-configurable DM relays (kind:10050), encrypted file attachments (kind:15), reply quotes and delivery state
- Lightning zaps (NIP-57) on messages and profiles whose author publishes a lud16/lud06. The client signs the zap request, fetches the invoice from the recipient's LNURL callback and hands it to the user's own wallet by QR code or lightning: URI. Receipts are watched on hardcoded relays (relay.damus.io, nos.lol). No custodial wallet in the app
- Live audio and video rooms inside a group: LiveKit rooms served by a companion the relay operator runs alongside the relay (token endpoint `/.well-known/nip29/livekit/<group-id>`), with the roster published as kind:39004 (a convention, not NIP-29). Clients on web, Android and desktop. Only a handful of relays run it today, for example pyramid.fiatjaf.com
- Inline image, video, and audio playback in chat
- Media uploads to any Blossom server the user adds (multi-server, mirrored) or a NIP-96 host picked from a built-in list, selectable in Settings. Encrypted DM attachments fall back to blossom.jumble.social when the chosen host rejects ciphertext blobs
- Emoji reactions with a categorized Unicode picker. Custom emoji (NIP-30) received from others are rendered inline, but the picker does not offer custom emoji to send
- Per-group unread state with focus-aware muting. Browser notifications and tab-title badges on web only; Android, desktop and iOS play a local sound and have no system notification, no tray integration and no push
- Discover feed: groups joined by the people you follow, ranked by how many of them are members
- Multiple accounts with one-tap switching
- Light and dark themes
- Multi-platform: Android, Desktop (JVM), Web; iOS in development
- Cryptographic identity via Nostr keys (no sign-up)
- Sign-in options: generated key, pasted nsec, password-protected ncryptsec (NIP-49), NIP-07 browser extension, NIP-46 remote signer (bunker), an external Android signer such as Amber (NIP-55), or Login with Google
- Login with Google: built on the promenade FROST threshold signer (Pomegranate). The key is generated client-side, split by a trusted dealer into shards held by separately operated signer services, and signing runs over NIP-46 through a coordinator (default auth.njump.me). Nostrord operates none of that infrastructure. The nsec is shown once at signup and can be exported later while a threshold of operators is reachable, never after Disconnect. Available on web, Android and desktop
- Open source under the Unlicense
## How It Works
1. User opens Nostrord (web, desktop, or mobile) and authenticates with a Nostr keypair
2. User connects to one or more NIP-29-compatible relays
3. User creates a new group on a relay or joins an existing one via invite
4. The relay enforces who can join, post, and moderate
5. Messages are signed with the user's private key and published to the relay
6. Other members receive messages in real time via WebSocket subscriptions
## Architecture
Nostrord is built with Kotlin Multiplatform. Shared business logic in commonMain runs on all platforms; native apps use Compose Multiplatform, the web app is a Kotlin/JS build with a React DOM UI. Platform-specific code handles crypto, secure storage, and browser integration.
- commonMain: shared NIP implementations, managers, view models, networking
- uiComposeMain: shared Compose UI for Android, desktop and iOS
- androidMain: EncryptedSharedPreferences, Android crypto
- jvmMain: Desktop crypto (secp256k1-kmp), JVM Preferences
- jsMain: NIP-07 browser extension, JS Ktor client, DOM-based web UI (the build live at web.nostrord.com)
