How it works
Cypress opens a browser with your app on one side and a log of commands on the other. Commands such as cy.get('button').click() retry automatically until they pass or time out, and time-travel snapshots let you hover over any step to see the page as it was at that moment. Because tests run in the same browser as the app, they can stub network requests and reach into the app's code directly.
It supports Chrome-family browsers, Firefox and Electron, with WebKit support still experimental, and tests are written only in JavaScript or TypeScript. Several tabs in one test are not supported, and visiting several domains needs cy.origin. The app is open source; Cypress Cloud is a paid service that records runs, spreads them across CI machines and replays failures.
Cypress pros and cons

- Component tests and end-to-end tests in one tool
- Large community and plugin ecosystem
Cons
- JavaScript and TypeScript only
- No multi-tab tests, and WebKit support is experimental
- Parallel runs and replays in CI lean on paid Cypress Cloud
