Selenium - Browser Automation
Selenium Automation - Browser Testing Specialists
Selenium is browser automation for testing. The platform automates browsers—Chrome, Firefox, Safari, Edge. Write tests in any language—Java, Python, JavaScript. We've built Selenium test suites that test web apps across browsers, catch regressions automatically. The WebDriver API means you control browsers programmatically. Selenium isn't fast—browser automation is slow—but if you need automated web testing, Selenium is the standard.
