Matter is an open-source application-layer connectivity standard for building secure and interoperable smart home ecosystems, guided by the Connectivity Standards Alliance.
Matter addresses fragmentation in the smart home market by providing a unified, IP-based standard that enables reliable communication between devices, mobile applications, and cloud services. The standard builds on proven technologies and is compatible with Thread and Wi-Fi network transports. It defines a complete specification covering device implementation, transport layers, security protocols, and the full device lifecycle from provisioning through operational management. The approach emphasizes security as a fundamental design principle, user control over device authorization, and a federated architecture with no single point of failure.
Manufacturers building connected home devices should adopt Matter to reduce development complexity and ensure their products work reliably with devices from other vendors. The standard suits any smart home product requiring certification and cross-device compatibility. The project is intended as a complete specification for implementers, with extensive documentation and testing infrastructure available to guide adoption.
The project maintains comprehensive testing dashboards including continuous integration test reports and nightly test results. Documentation is actively maintained with coverage reports tracking the specification implementation. The codebase includes build, test, and tooling components supporting the full development lifecycle for Matter-compliant devices.
