OTBR Thread Certificate

Certify with OpenThread

Other platforms running OpenThread can be certified as Thread Certified Components. OpenThread can also be used for a product certification, which carries the "Built on Thread" badge.

For more information about the difference between Thread and OpenThread as it relates to certification, see the Thread Group FAQ.

Why certify?

Certification indicates to customers that your product is fully Thread compliant, and that it works with other Thread products. Product certification is required to ship a product based on OpenThread, and to claim that a product supports Thread.

Certifying a product running OpenThread provides an added benefit, given that OpenThread itself is a Thread Certified Component. Certification time and costs are generally reduced, as the Thread Group's test houses are already familiar with OpenThread as a reference stack.


Certification testing is done with the GRL Thread Test Harness software, available for download to Thread member companies. To increase the likelihood of a successful Thread certification using OpenThread, we recommend running and passing all certification tests in a local setup prior to submission to the Thread Group.
