Cypress

Cypress is a frontend test automation platform that makes it fast, easy, and reliable to test anything that runs in a browser. Built for modern JavaScript applications, the open-source Cypress App runs directly in the browser alongside application code, enabling end-to-end, integration, component, and unit testing with real-time reloading, automatic waiting, and time-travel debugging. The Cypress Cloud platform extends the open-source tool with test analytics, parallelization, CI/CD integrations, and team collaboration features. Founded in 2015 by Brian Mann, Cypress has become one of the most widely adopted JavaScript testing frameworks globally, supporting developers from individual contributors to enterprise engineering teams.
