Sauce Labs

Sauce Labs is a cloud-based platform for automated testing of desktop and mobile applications. It is designed to be instantly scalable, since it is optimized for continuous integration workflows. (The vendor says that when tests are automated and run in parallel on multiple virtual machines across many different browser, platform and device combinations, testing time is reduced and developer time is freed up from managing infrastructure.) The Sauce Labs testing cloud is intended to be paired with a CI system. According to the vendor, this combination allows developers to easily test desktop and hybrid, native and mobile web applications early on in their development cycles, continuously and affordably.
