Raven works online and offline — automatically switching between internet and Bluetooth mesh based on your connectivity. End-to-end encrypted. Open source.
Messages find their way through internet, Bluetooth mesh, or both. No dead zones. No "try again later."
End-to-end encrypted with AES-256. Even mesh relay nodes can't read your messages. Your keys never leave your device.
Our security-critical code is public on GitHub. Audit it, verify it, trust it. Licensed under AGPL-3.0 like Signal.
You don't need to do anything. Raven intelligently routes every message through the best available path.
If internet is available, messages go through the server immediately. Fast, seamless, secure.
If you're nearby, devices deliver directly via Bluetooth — no internet needed.
Nearby devices carry the message until one can deliver it — or until it reaches the recipient.
Private conversations over internet or mesh. Messages always find a way.
Posts spread locally via mesh when offline, then sync globally when reconnected.
Military-grade encryption with Ed25519 signing and HMAC authentication on every message.
Record and send voice messages with waveform visualization and playback control.
Built-in reporting tools — AI-assisted content triage keeps the community safe.
Available in English, Persian (RTL), Spanish, German, and Chinese with full parity.
Raven works great online — but its real power unlocks when more people in your area install it. Each phone becomes a mesh relay node, extending offline coverage for everyone nearby. The more Raven users around you, the stronger and more reliable the mesh becomes.
Install Raven and invite your friends — you're building a communication network that works even when the internet doesn't.
