Products & Services
Hosted AI QA agent that tests websites and mobile apps through real user journeys described in natural language; provides screenshots, recordings and actionable bug reports, and can run on pull requests, deploy previews, CI pipelines and production schedules.
Open-source, Apache-2.0 TypeScript end-to-end testing framework for web and mobile apps. It combines exact locators and assertions with agent steps described as goals, and replays compatible cached actions to reduce repeated model calls.
Open-source client/CLI for running TesterArmy tests from a terminal, CI job or coding agent; includes agent skills and JSON output.
Open-source API-testing CLI for coding agents that uses an OpenAPI specification to sweep, fuzz and record findings with safe defaults and write protections.
Market Position
TesterArmy positions itself as an agentic, goal-based alternative to brittle scripted automation: its agents interact with web and mobile apps like users, can test without source-code access, and cover flows such as OAuth and OTP. Its comparison set includes Rainforest QA, Momentic, QA.tech, Mabl, testRigor, Functionize, Playwright, Cypress, Selenium, BrowserStack, QA Wolf, Meticulous, Revyl and TestSprite.

Board of Directors
Founding Story
The founders say they started TesterArmy after becoming frustrated that QA was the slowest part of shipping: manual testing is slow and scripted tests become brittle as interfaces change. Their initial vision was an army of AI testers that could click, type, navigate and verify real user journeys from plain-language instructions, without requiring source-code access or maintained selectors.
