Bromal

Lightweight messaging server for Matrix protocol

Bromal is a lightweight opensource messaging server, that uses the Matrix protocol. It is being developed for the efficient deployment of federated messaging systems with modest resource requirements, as a result, it could be deployed even on small servers, including VPS, without sacrificing essential functionality. The project aims to support server-to-server federation, state resolution for different room versions, end-to-end encryption, a full-featured messaging module, built-in VoIP, automatic TLS certificate acquisition via Let's Encrypt using the ACME protocol, as well as the ability to create a cluster for larger installations.
