As answered by people managing Marathon Cloud and BrowserStack.
Marathon Cloud's answer
The device pool is sized for every run from your suite's own history, targeting 15 minutes, so there is no parallel device count to buy or tune. Failed tests are retried individually on a different device, and tests with a flaky history are retried preventively, so the report separates flaky from failed. It is built on Marathon, the open-source mobile test runner, so there is no lock-in: the same runner can bring execution back in-house.
Marathon Cloud's answer
You pay $2 per hour per Android device and $3 per hour per iOS device, billed per second, instead of monthly per-parallel plans. You can start the same day with 50 free device hours and one CLI command, without a sales call. It runs Espresso, XCUITest and Maestro on emulators and simulators from any CI, which is where most UI suites run anyway; real-device clouds are better when a test truly needs physical hardware.
Marathon Cloud's answer
Mobile engineering teams, including Android and iOS developers, SDETs and platform or DevOps engineers, who want their full UI test suite to run on every pull request. Typically companies with an Espresso, XCUITest or Maestro suite that has outgrown one CI machine or a per-parallel device cloud.
Marathon Cloud's answer
Marathon started in 2018 as an open-source test runner for Android and iOS, built to make large UI suites fast and stable through smart batching, sharding and per-test retries. It is used by teams running some of the largest consumer apps. Marathon Cloud launched in 2022 as the hosted version: the same engine, with devices, scaling and retries handled for you. MarathonLabs (TestWise Pte. Ltd., Singapore) is bootstrapped and profitable.
Marathon Cloud's answer
Kotlin (the open-source Marathon runner), Go+Rust (cloud services and the CLI), Svelte and TypeScript (web), gRPC, Docker, Android emulators, and iOS simulators on Apple hardware.
