About Selenium

Selenium is a brand that specializes in automating browsers. With a recognizable green logo, Selenium offers a range of products and services to cater to various needs. Primarily used for automating web applications for testing purposes, Selenium's capabilities extend beyond that. It can also automate tedious web-based administration tasks, saving time and effort. If you're looking to create robust regression automation suites and tests, Selenium WebDriver is the ideal choice. It provides language-specific bindings to drive browsers in the most efficient way. For quick bug reproduction scripts or automation-aided exploratory testing, Selenium IDE is a Chrome, Firefox, and Edge add-on that offers simple record-and-playback functionality. And if you want to scale your testing efforts, Selenium Grid allows you to distribute and run tests on multiple machines, managing multiple environments from a central point. With the recent release of Selenium 4.11.0, the brand continues to stay at the forefront of browser automation technology. Support the Selenium project and contribute to its success today.
