Replay

Replay is an automated testing tool that explores web applications, records sessions, and provides root causes for bugs.

Replay QA is an automated testing tool designed to find bugs in AI-built web applications and modern software projects. It operates in two ways by connecting to a GitHub repository for continuous testing or by testing a running web application via a provided URL. The platform explores the app, records every session, writes Playwright tests automatically, and delivers structured bug reports with root causes and suggested fixes. It supports integrations with GitHub, Playwright, and Cypress, making it suitable for engineers, solo founders, and development teams. The service stands out by eliminating the need to write test suites or configure complex testing pipelines before shipping code.
