AWS Device Farm

AWS Device Farm lets you test Android, iOS, and web apps on real physical devices hosted in the cloud. It handles the infrastructure for you, so you don’t need to maintain a physical lab. You just upload your builds and run tests against actual hardware.

It fits teams wanting to scale testing without buying devices. The free trial is available, but there is no permanent free tier. You pay per minute of usage, which can add up quickly if you run extensive test suites regularly.
