 - [Cypress](https://www.cypress.io/) has an informative graphical interface, excellent debuggability, built-in assertions, stubs, flake-resistance, and snapshots. As mentioned above, it provides stable support for [Component Testing](https://docs.cypress.io/guides/component-testing/introduction). Cypress supports Chromium-based browsers, Firefox, and Electron. WebKit support is available, but marked experimental. Cypress is MIT-licensed, but some features like parallelization require a subscription to Cypress Cloud.
