Download Selenium – Open-Source Web Browser Automation and Testing Framework

Selenium is the world’s most widely used open-source framework for automating web browsers. It enables developers and QA engineers to write automated tests that control browsers programmatically — clicking buttons, filling forms, navigating pages, and verifying content — across Chrome, Firefox, Edge, Safari, and other browsers.

Selenium consists of several components: Selenium WebDriver for writing tests in Python, Java, C#, JavaScript, Ruby, or Kotlin; Selenium IDE for recording and playing back browser interactions without coding; and Selenium Grid for running tests in parallel across multiple browsers and machines simultaneously.

Whether you are building automated regression test suites, scraping dynamic JavaScript-rendered web pages, or running cross-browser compatibility checks, Selenium is the industry-standard tool trusted by thousands of companies worldwide.
