OpenThread is Google's open-source, Thread Certified implementation of the Thread networking protocol, covering all Thread networking layers (IPv6, 6LoWPAN, IEEE 802.15.4, Mesh Link Establishment, Mesh Routing) and device roles. It is OS and platform agnostic with a narrow platform abstraction layer and small memory footprint, supporting SoC, RCP, and NCP designs.

Use cases

• build a Thread mesh network for smart home devices
• implement Thread stack on an embedded SoC like nRF52840 or EFR32
• simulate a Thread network in Docker without hardware
• add IPv6 low-power mesh connectivity to IoT products
• run a Thread Radio Co-Processor (RCP) with ot-daemon
• certify a product as a Thread Certified Component
• build a Thread border router connecting Thread to Wi-Fi/Ethernet

When to choose

• you need a certified, spec-complete Thread 1.4.0 implementation
• you target resource-constrained embedded hardware with a small footprint
• you want portable code with a narrow platform abstraction layer
• you need SoC or co-processor (RCP/NCP) deployment options
• you want vendor-backed open source with broad silicon partner support

When to avoid

• you need Wi-Fi, Bluetooth, or Zigbee rather than Thread/802.15.4
• you want a turnkey application rather than a networking stack to integrate
• your platform lacks the memory or a port of the OpenThread platform layer
• you need a high-level SDK with GUI tooling rather than a C/C++ stack
