 # What is Zalenium?
 A Selenium Grid extension to scale up and down your local grid dynamically with docker containers. It uses [docker-selenium](https://github.com/elgalu/docker-selenium) to run your tests in Firefox and Chrome locally, and when you need a different browser, your tests get redirected to [Sauce Labs](https://saucelabs.com/) and/or [BrowserStack](https://www.browserstack.com/) and/or [TestingBot](https://testingbot.com/).
