Is UnitCert really free?

Yes. UnitCert is 100% free for individual device testing. You can run unlimited hardware tests and generate up to 25 certified reports per month at no cost. Pro and Business plans are available for teams needing batch testing, CSV export, and custom templates.

Do I need to download anything?

No. UnitCert runs entirely in your browser. There's nothing to download, install, or configure. Just open the website and start testing.

What devices does UnitCert support?

UnitCert supports Chromebooks, Windows laptops, and MacBooks. Each device type has a customized test suite that covers keyboard, trackpad, screen, camera, microphone, speakers, touch screen, and network diagnostics.

How does report verification work?

Every UnitCert report includes a unique verification ID (starting with UC-). Anyone can enter this code or paste the report link on our verification page to confirm the diagnostic results are authentic and unaltered.

Can I test multiple devices at once?

Yes. UnitCert Pro includes batch testing mode where you can create a batch, share a single test link with your team, and track progress across all devices from a central dashboard. Export results as CSV for your records.
