Overview

Selenium is the veteran browser automation framework. It’s been the industry standard for web testing for over a decade and supports more browsers and programming languages than any alternative.

Key Features

Multi-Language: Java, Python, C#, Ruby, JavaScript, Kotlin
Multi-Browser: Chrome, Firefox, Safari, Edge, IE
Selenium Grid: Distributed test execution
WebDriver W3C Standard: Industry standard protocol

Why It Matters

While Selenium has been superseded by Playwright and Puppeteer for many use cases, it remains important for legacy systems and environments where WebDriver is the only option. Its cross-browser support is unmatched.
