Testerarmy

TesterArmy is an AI-powered QA testing platform (Y Combinator, batch P26) whose browser and mobile agents test web and mobile apps like a real user - navigating pages, filling forms, handling login, OAuth and OTP flows, and catching broken flows, rendering bugs and confusing UX. You describe tests in plain English and the agent runs them in the TesterArmy cloud (or locally), on every GitHub pull request or on a schedule, returning screenshots, recordings and actionable bug reports. It exposes a public REST API (bearer API-key auth), a first-party CLI (testerarmy / ta), inbound trigger webhooks, and mobile app upload and testing.

Testerarmy publishes 5 APIs on the APIs.io network, including Groups API, Projects API, Test Runs API, and 2 more. Tagged areas include Company, QA, Software Testing, Browser Automation, and AI Agents.

The Testerarmy catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Testerarmy’s developer surface includes authentication, CLI, sandbox, documentation, API reference, getting-started guide, pricing, and 19 more developer resources.
