Matrix.org
Matrix is an open standard for interoperable, decentralised, real-time communication over IP. It can be used to power Instant Messaging, VoIP/WebRTC signalling, Internet of Things communication – or anywhere you need a standard HTTP API for publishing and subscribing to data whilst tracking the conversation history.
Maintained by the non-profit Matrix.org Foundation, we aim to create an open platform which is as independent, vibrant and evolving as the Web itself… but for communication.
