Overview

Cypress is an open-source testing framework designed to simplify end-to-end and component testing for modern web applications. It runs directly in the browser, allowing developers to write, run, and debug tests with a simple API and real-time feedback. The platform combines fast test execution with powerful debugging capabilities, including visual debugging in the browser's developer tools.

Beyond the open-source app, Cypress Cloud offers a SaaS platform for scaling tests across CI/CD pipelines. It includes features like test parallelization, visual reviews, AI-powered test summaries, and analytics to help teams optimize their testing strategy. The platform also provides AI-assisted test generation through natural language prompts and automated accessibility checking.
