Chat freely.
No servers. No surveillance.
Harbor is a free, open-source, peer-to-peer chat app. Your messages and data stay on your device — no company can read them, sell them, or take them away.
End-to-End Encrypted
Every message is encrypted using Ed25519 and X25519 keys that never leave your device. Only you and your contact can read your conversations.
No Central Servers
Harbor connects peers directly using libp2p. There is no company server routing your messages — the network belongs to its users.
Local-First
Your data is stored on your own machine in a local SQLite database. You own your history, your contacts, and your identity.
Free & Open Source
Harbor is fully open source. Inspect the code, contribute, or fork it. No subscriptions, no ads, no freemium limits.
Desktop Native
Built with Tauri, Harbor runs as a lightweight native app on Windows, macOS, and Linux — not a browser tab dressed up as an app.
Easy Contact Sharing
Share a simple link to add contacts. No account creation, no phone number required — just send the link and connect.
