99tests

99tests is a crowdsourced testing service in which real testers run test cases by hand on the phones, laptops and browsers they own. Test cases are generated with AI and executed by people.

Customers submit a build link or web address and choose the target devices. They receive a human-verified report with pass or fail results for each test case, screenshots of failures, reproduction steps and device details. The company is based in Bengaluru, India.

99tests is a commercial service with fixed-price Starter, Standard and Deep packages; unfilled sessions are credited back.
