Selenium
Selenium is the original open-source browser automation framework for driving web browsers natively, supporting all major browsers and programming languages.
Selenium is a mature, comprehensive browser automation framework that drives browsers natively through WebDriver. It supports browser testing and automation through language bindings and browser drivers.
Key Features:
- WebDriver Protocol - Drive browsers natively as real users would, across all major browsers
- Multi-Language Bindings - Write automation in Python, Java, JavaScript, C#, Ruby, and more
- Selenium Grid - Distribute and scale tests across multiple machines and environments
- Selenium IDE - Record-and-playback browser interactions for quick script generation
- Vast Ecosystem - Extensive community, plugins, and integrations built over 20+ years
Whether you're scraping at scale, running regression tests, or automating browser workflows, Selenium provides a configurable foundation for browser automation.
Quick verdict
Selenium is for teams that need mature browser automation across major languages and real browsers. It is not a managed scraping API, so proxies, extraction, monitoring, and infrastructure are on you.

Frequently asked questions
Can Selenium be used for browser automation?
Yes. Selenium WebDriver controls a browser through code, allowing scripts to open pages, interact with elements and check application behavior. It can run against a local browser or a remote browser through Selenium Server.
Sources (checked ): Selenium WebDriver
What are the limitations of Selenium?
Selenium automates browser interactions, so a test suite still needs suitable locators, synchronization and test design. Its documentation discourages using browser automation for performance testing and CAPTCHA automation. Browser compatibility and remote execution also depend on the browsers and infrastructure you configure.

Which is better, Playwright or Selenium?
The choice depends on your browser requirements and existing tooling. Selenium supports WebDriver-based automation and Selenium Grid for remote, parallel execution. Playwright provides a unified API for Chromium, Firefox and WebKit. Playwright Test is its Node.js test runner, with built-in assertions, isolation and parallel execution. Compare those features with your project’s needs before choosing.
