What is it?

Vector is a messenger app for private one-to-one chats, group communities, voice and video calls. Accounts are created with a keypair alone, with no phone number, email, or KYC, and messages, files, and communities are end-to-end encrypted. Direct messages use NIP-17 with NIP-44 encryption and NIP-59 gift wraps, and communities use the Concord protocol.

The app runs on Nostr relays and can route connections through Tor (built in), I2P via a user's own router, or the clearnet. Desktop builds cover Windows, macOS and Linux, and Android is supported; Vector Web runs the full app in a browser. Photos have EXIF and location data stripped before sending, and the app offers self-destructing messages, PIN or biometric local lock, and remote signers via NIP-46 or Amber.

A bare build variant drops optional features such as local AI transcription, Tor, I2P and video compression for a smaller footprint. The project also provides a Rust SDK for building bots and an MCP server with 61 tools for AI agents.
