Matrix.org
Verified working Sep 19, 2026
An open messaging protocol for federated, secure communication.
Matrix.org is the home of Matrix, an open protocol and ecosystem for decentralized real-time communication. The site points users to Matrix clients, servers, bridges, integrations, SDKs, hosting options, the formal specification, and Foundation governance updates.
Why it stands out
- Federated design lets different homeservers participate in the same communication network.
- The site covers the full ecosystem, not just one client app or hosting provider.
- Developers get both a formal specification and SDK pointers for building on the protocol.
- Foundation governance, working groups, reports, and elections are published alongside technical resources.
- Bridges and integrations make Matrix useful as a connector between communication tools.
Good to know
- Matrix.org is mainly the protocol and ecosystem hub; choosing a client, server, or host requires extra evaluation.
- Running a homeserver is more technical than signing up for a single centralized chat service.
- The quality of rooms, bridges, moderation, and uptime can vary depending on the homeserver and client used.

Explore clients, homeservers, bridges, and integrations across the Matrix ecosystem. Build communication apps, bots, or services using Matrix SDKs and the protocol specification. Follow ecosystem news through the weekly This Week in Matrix digest.

Technical Notes
- Matrix is defined through an open protocol specification for interoperable client-server and server-server communication.
- Developer resources include SDKs for building Matrix clients, bots, bridges, and application services.
