About 99tests
99tests is a crowdsourced, fixed-price testing service for mobile apps and websites. Teams upload a build or URL, provide test cases—including AI-generated cases—and choose device and browser targets. Testers in India run the cases on their own phones, laptops, and browsers. 99tests returns a human-verified report with pass/fail results, reproduction steps, expected and actual behavior, device and OS details, and screenshots or recordings for findings. Its hosted workflow also supports an MCP server that compatible coding clients can use to look up packages, create jobs, check status, and retrieve reports; payment is completed through browser checkout. Teams use 99tests for release checks and regression testing across real devices without maintaining an in-house device lab or QA team. Fixed-price packages specify session, device or browser, and test-case limits, along with turnaround times. 99tests also offers separate free online QA utilities.
