Kant, a relay-first messaging layer
Kant presents a self-hostable, peer-to-peer messaging infrastructure built around end-to-end encryption and relays that retain no plaintext.
- For
- Teams designing self-hosted secure communications
- Worth noticing
- The relay is described as holding zero bytes of plaintext, with health, readiness, metrics, and registry endpoints exposed.
Field notes
The homepage frames Kant as infrastructure for organizations that want to operate their own relay rather than outsource message routing. Its stated stack combines libp2p, circuit-relay v2, Noise, yamux, libsodium, X3DH, and Double Ratchet, with operational visibility through health and Prometheus endpoints. Group messaging and chunked, resumable encrypted file transfer are listed alongside the core transport design, while the site directs protocol discussion and roadmap work to an open Discord community.
