Semaloop vs TesterArmy
TesterArmy is a YC-backed agent that tests web and mobile apps, on simulators and emulators for mobile. Semaloop runs natural language tests on real iPhones and Android emulators against every build you ship.
What TesterArmy is
TesterArmy turns natural language instructions into test plans and runs them against your app. For mobile it currently runs on simulators only, and says real devices are available on request: you build an iOS Simulator .app bundle, upload it, and its agent drives it. It also generates a test plan from a pull request’s title, description and changed files, and a PR with nothing user-visible can skip the run.
Where they differ
| Semaloop | TesterArmy | |
|---|---|---|
| What the tests run on | Real iPhones on iOS; emulators on Android | Simulators and emulators today; real devices on request |
| Getting a build in | Ingested from TestFlight, or an APK pushed from CI | You produce and upload a simulator build |
| What triggers a run | Every new build, every active test | Pull requests scoped to what changed, plus manual, CLI, API and CI runs |
| Real-device-only failures | In scope on iOS — push, IAP, camera, warm hardware | Outside what a simulator reproduces |
| Pricing | Published, per execution | Published per test run: Hobby $99 a month for 250 runs, Startup $299 for 1,000 |
Choose TesterArmy if
- You want the gate at the pull request rather than the build, and scoping a run to the changed files is worth more to you than device realism.
- Your app’s risk genuinely lives in layout and logic, not in the hardware-dependent flows.
- You want one tool covering web and mobile together.
Choose Semaloop if
- Your iOS risk is in the flows a simulator cannot produce: one-time passcodes over SMS, push, in-app purchases, the camera, a Safari redirect handing back to the app. We run those on real iPhones.
- You would rather test the build you actually ship than a separate simulator binary.
- You want coverage that does not depend on a diff looking risky enough to warrant it.
