Y Combinator-backed TesterArmy automates web and mobile app testing using AI agents that execute end-to-end checks in natural language, eliminating manual testing workflows and static script maintenance.
The platform, founded by Oskar, Szymon, and Piotr, replaces traditional QA processes with agentic automation. Users specify tests in natural language rather than writing code, with the system handling execution and management autonomously.
TesterArmy runs tests both pre-deployment and in production environments. The founders built the entire platform around agent architecture, allowing autonomous agents to reliably execute tests while coding agents manage platform operations.
The approach targets a pain point in software development: the time-consuming cycle of manual testing or maintaining brittle test scripts that break with code changes. By accepting test specifications in plain language, TesterArmy aims to reduce QA overhead while improving coverage.
The startup joins a growing wave of AI-driven development tools, positioning automated testing as a core workflow rather than a separate process. The platform is currently available at tester.army.
