* fix(e2ee): bind the key epoch into wrapped room-key offers

The holder's rotation counter now rides inside encrypted_key as a
versioned header and is bound as AES-GCM additional data, so a receiver
can tell a current room key from a superseded one. Receivers keep a
per-sender high-water mark and apply an offer only at or above it; the
mark resets when that sender announces a fresh ephemeral key. Blobs in
the pre-epoch layout are still accepted for holders on the older build
(compat path, scheduled for removal next release). No server or schema
change: the relay treats encrypted_key as opaque.

* feat(e2ee): show a per-call session fingerprint for every voice peer

A peer with no published identity key has no safety number, so the TOFU
badge gave the user nothing to compare out of band. Every accepted
announce now also carries a fingerprint of the peer's ephemeral session
key, shown on the unverified badge and labelled as changing every call
and not an identity; the local user's own session fingerprint is shown
on their row so it can be read back. safetyNumber is unchanged and stays
null for unverified peers.

CI Release Status Go Tauri Platforms License: AGPL-3.0

OwnCord

A self-hosted chat app I build for me and my friends — text channels, voice and video, and a server you actually own.

Alpha, and a hobby project. This is something I build for fun and run for a small group of friends. It isn't a product, there's no support, and it isn't production-ready. Expect rough edges, rapid changes, and the occasional breaking change.

Don't use it for anything sensitive.

It's a Go server plus a Tauri desktop client: real-time messaging, voice/video via LiveKit, file sharing, and a web admin panel. Run the server on a spare box or a VPS, hand your friends an invite code, and that's the whole thing.

How it's built

Most of the implementation is generated with AI tooling, with quality held up by automated checks — CI, tests, linting — and by me and my friends actually using it. That keeps iteration fast, and it also means behaviour can change quickly between releases.

What works right now

Area Status
Core chat flow Working in alpha
Voice/video Working in alpha
Admin panel Working in alpha
Security hardening Ongoing review passes; findings and their statuses are tracked in the dated audits in docs/ (see the Docs Index below)

Platform Support (Current Releases)

Component Windows x64 Linux x64 Linux ARM64
Server binary Yes Yes Not yet
Desktop client Yes (NSIS installer) Yes (AppImage, .deb) Yes (AppImage, .deb)
Docker server N/A Build from source (compose) Not yet

Start Here

Quick Start

Option A: Prebuilt binaries

  1. Download assets from Releases (binaries, checksums, signatures, and a full source snapshot per release).
  2. Run the server binary:
    • Windows: chatserver.exe
    • Linux: ./chatserver
  3. Open https://localhost:8443/admin and complete the setup wizard — it creates your Owner account and configures the server for you (settings are saved to config.yaml automatically).
  4. Generate invite codes in the admin panel and share them with friends.

Option B: Docker (Linux server)

cd Server
cp .env.example .env
cp livekit.yaml.example livekit.yaml
# Edit both files before starting
docker compose up -d

See the full setup guide in docs/deployment.md.

The client uses TOFU (Trust On First Use) for self-signed certificates: it prompts once, then pins the certificate for future connections.

What OwnCord Already Has

  • Real-time channels and direct messages over WebSocket
  • Voice/video channels via LiveKit — the LiveKit server binary is downloaded and managed for you
  • Invite-only registration and role-based permissions
  • Web admin panel with logs, backups, and update tooling
  • File uploads and inline media rendering
  • TOTP 2FA support and API rate limiting
  • Desktop client auto-update with signature verification
  • WASM plugin system (slash commands; sandboxed, default-disabled — enable via plugins.enabled and build with -tags wazero)
  • GIF picker — off by default; each server supplies its own Klipy key via gif.api_key (setup)

See deeper feature and architecture docs in docs/architecture/ and docs/protocol.md.

Architecture

Two main components:

  • Go server (REST API, WebSocket hub, SQLite, admin panel)
  • Tauri v2 desktop client (Rust backend + TypeScript frontend)

Build and Test

Prerequisites

  • Go 1.26+
  • Node.js 20+
  • Rust stable (client builds)

Build from source

# Server (Windows)
cd Server
go build -o chatserver.exe -ldflags "-s -w -X main.version=1.2.0-alpha.3" .

# Server (Linux)
cd Server
CGO_ENABLED=0 go build -o chatserver -ldflags "-s -w -X main.version=1.2.0-alpha.3" .

# Client
cd Client/tauri-client
npm install
npm run tauri build

Core verification commands

# Server
cd Server
go test ./...

# Client
cd Client/tauri-client
npm run typecheck
npm run lint
npm test

For the full command set, use docs/contributing.md.

Configuration

On first run, the server generates config.yaml and a local data/ directory:

data/
├── chatserver.db
├── certs/
├── uploads/
└── backups/

Key options include TLS mode, upload limits, LiveKit settings, and admin CIDR restrictions. See docs/server-configuration.md.

Security and Vulnerability Reporting

  • For vulnerabilities, use GitHub Security Advisories (private disclosure flow).
  • Do not open public issues for security bugs.
  • Read full policy and hardening notes in docs/security.md.

Update Signing Notes (Maintainers)

Client and server update signing keys are intentionally separate.

Required Actions secrets for release signing:

  • TAURI_SIGNING_PRIVATE_KEY
  • TAURI_SIGNING_PRIVATE_KEY_PASSWORD
  • SERVER_UPDATE_SIGNING_PRIVATE_KEY
  • SERVER_UPDATE_SIGNING_PRIVATE_KEY_PASSWORD

When rotating the server updater key, update Server/updater/server_update_public_key.txt and use staged rollover for live fleets.

Docs Index

Contributing

  1. Create a branch from dev (the active development branch).
  2. Keep changes focused and tested.
  3. Open a PR targeting devdev is merged to main for releases.
