What AltTester is

AltTester is a game testing tool for projects built with 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. Its two named plans describe connection capacity and execution environments: AltTester Lite includes one connection and lists PC, Mac, Android, iOS, and WebGL, while AltTester Pro includes two parallel connections and lists macOS, Windows, and Linux CI/CD batchmode. AltTester has a free plan, and the pricing note gives paid access from €75/user/mo (annual) alongside a 30-day trial. The listed price is a starting point for paid access; prices for the individual Lite and Pro plans are not provided. AltTester was founded in 2018. Its stated scope includes automated execution of tests, while playtesting workflows and performance monitoring are not included.
