The official open-source SDK for Matter (formerly Project CHIP), the Connectivity Standards Alliance's IP-based smart home connectivity standard. It provides the data model, networking, security, and commissioning layers needed to build interoperable Matter devices and controllers across many chip platforms.
Use cases
- build a Matter-certified smart home device
- implement a Matter controller or commissioner app
- add Matter support to an ESP32 or embedded firmware
- develop a Thread or Wi-Fi connected home accessory
- test interoperability between Matter devices
- port the Matter stack to a new SoC platform
When to choose
- you are building or certifying a Matter end device or controller
- you need the reference implementation maintained by the CSA
- you target supported platforms like ESP32, Nordic, Silicon Labs, TI, or Linux
When to avoid
- you need Zigbee, Z-Wave, or other non-Matter protocols
- you want a high-level consumer smart home app rather than device SDK work
- your platform is not among the supported chip vendors
