AltTester

AltTester is a game test automation tool for projects using Unity or Unreal Engine. It supports automated test execution in a hybrid test environment and targets PC, Mac, Windows, Android, iOS, WebGL and Nintendo Switch. The software runs on Linux, macOS and Windows. AltTester Lite lists one connection and supports PC, Mac, Android, iOS and WebGL. AltTester Pro lists two parallel connections and macOS, Windows and Linux CI/CD batchmode. A free plan is available, alongside a 30-day trial and paid access from €75/user/mo when billed annually. AltTester was founded in 2018. Its published scope does not include playtesting workflows or performance monitoring. The plan details therefore center on connection capacity, operating systems and execution environments rather than those additional testing areas.

AltTester focuses on automated game-test execution across multiple engines and platforms.

AltTester suits game teams automating tests for Unity or Unreal projects across its listed target platforms. It is relevant when hybrid execution and CI/CD environments matter.
