Developer Realman78 has released a beta version of Kiyeovo, a desktop P2P messenger built with Electron, React, and libp2p. The app features two completely isolated network modes: fast mode for lower latency with WebRTC calls support, and anonymous mode using Tor message routing for enhanced privacy. The messenger began as a CLI application for a graduate thesis before evolving into its current desktop form.

Kiyeovo uses separate protocol IDs, DHT namespaces, and storage scopes for each mode to prevent data crossover. Messages work peer-to-peer when both parties are online, falling back to DHT offline buckets when one party is unavailable. Group chats utilize GossipSub for real-time messaging, with offline messages encrypted and stored for later retrieval. The beta supports E2E encryption, file sharing, and 1:1 audio/video calls in fast mode, though group calls remain a planned feature for the full release.

The developer emphasizes that Tor mode introduces noticeable latency and offline delivery operates on an "eventually consistent" basis rather than immediate guarantee. Beta users can connect to existing bootstrap nodes in Frankfurt, Amsterdam, and New York, with infrastructure scheduled to shut down April 19th, 2026. The full release promises UX improvements, group calls, screen sharing, performance enhancements, and a local API interface.
