Berty is an open-source, peer-to-peer messaging app with end-to-end encryption that works with or without internet access, using libp2p, IPFS, and Bluetooth Low Energy. It requires no phone number, email, or personal data and is designed to resist censorship and surveillance.

Use cases

• message people without internet or cell coverage
• chat anonymously without a phone number
• communicate securely under censorship or surveillance
• send encrypted messages over bluetooth without a server
• self-hosted serverless messaging for privacy
• offline-first p2p messenger for activists

When to choose

• you need messaging that works fully offline or without trusted infrastructure
• anonymity and metadata minimization are critical
• you want an open-source, distributed alternative to Signal or Briar

When to avoid

• you need polished, guaranteed-available mobile messaging for mainstream users
• you require push notifications or multi-device sync with central servers
• you need a stable production app on Android, which is temporarily unavailable
