Sauce Labs Cross-Browser Testing vs Selenium

Sauce Labs Cross-Browser Testing helps teams test websites and apps across browsers, operating systems, and devices to identify errors. Its cloud service provides browsers, emulators, simulators, and real devices, with test suites able to run in parallel across browser and operating-system combinations. Live sessions include Chrome DevTools and Safari Web Inspector; test results can include video, screenshots, Selenium logs, and metadata. Sauce Labs lists thousands of browser and operating-system combinations, 1,700+ emulators and simulators, and 7,500+ real iOS and Android devices. It aims to support new releases within 48 hours, though configurations may differ by region. Integrations include GitLab, GitHub Actions, Azure DevOps, Jenkins, CircleCI, Selenium, Appium, Cypress, Playwright, and Testmo. The self-serve plans each include one parallel test. Live Testing starts at $39 a month billed annually, or $49 month to month; Virtual Device Cloud is $149 a month billed annually, or $199 month to month; Real Device Cloud is $199 a month billed annually, or $249 month to month. A free trial is available; enterprise pricing is on request.

Selenium is a free suite of tools for automating web browsers, primarily to test web applications. WebDriver provides language bindings for controlling browsers locally or remotely, and is a W3C Recommendation. The main project supports.NET/C#, Ruby, Java, Python, and JavaScript. Selenium IDE is a browser add-on for recording and replaying interactions in Chrome, Firefox, and Edge. For distributed tests, Selenium Grid spreads work across machines and combinations of browsers and operating systems. Grid offers Standalone, Hub and Node, and Distributed configurations; Docker and Kubernetes deployment resources are also linked. Selenium Manager can discover, download, and cache browser releases and drivers. Documentation covers browser-specific functionality for Chrome, Edge, Firefox, Internet Explorer, and Safari, and names GitHub Actions and Jenkins as CI/CD examples. Selenium began in 2004 at ThoughtWorks in Chicago. Grid has no authentication by default, and the project advises restricting external access and placing it behind a secure network. The latest Opera driver functionality is not supported, and that driver is officially unsupported. Selenium costs nothing.
