Selenium Core
Selenium is a result of the continuous efforts by an engineer named Jason Huggins from ThoughtWorks. Being responsible for the testing of an internal Time and Expenses application,
he realized the need for an automation testing tool in order to get rid of repetitive manual tasks without compromising the quality and accuracy.
As a result, he built a JavaScript program, named as “JavaScriptTestRunner” in early 2004 that could automatically control the browser’s actions which seemed very much similar to that of a user communicating with the browser.

Selenium IDE (Selenium Integrated Development Environment)
Selenium IDE was developed by Shinya Kasatani. While studying Selenium Core, he realized that this JavaScript code can be extended to create an integrated development environment (IDE), which can be plugged into Mozilla Firefox. This IDE was capable of recording and playing back the user actions on a Firefox instance to which it was plugged-in.
Selenium RC (Selenium Remote Control)
Selenium RC is a tool written in Java to allow a user to construct test scripts for a web-based application in any programming language he/she chooses. Selenium RC came as a result to overcome the various disadvantages incurred by Selenium IDE or Core.

Selenium Grid
With selenium RC, the life of a tester has always been positive and favourable until the emerging trends raised a demand to execute the same or different test scripts on multiple platforms and browsers concurrently so as to achieve distributed test execution, testing under different environments and saving execution time remarkably. Thus, catering these requirements Selenium Grid was brought into the picture.
Selenium WebDriver
Selenium WebDriver was created by yet another engineer at ThoughtWorks named Simon Stewart in the year 2006. WebDriver is also a web-based testing tool with a subtle difference with Selenium RC.
