IETester: Test Websites in Different IE Versions

Free utility for testing websites on various Internet Explorer versions without virtual machines

What is IETester?

IETester is a free utility developed by RTools Technology that allows web developers and designers to test websites and web apps across multiple versions of Internet Explorer on the same computer. It works by emulating older versions of IE from 5.5 up to the latest IE11, without needing to set up multiple virtual machines.

One of the main benefits of IETester is that it saves significant time and effort compared to manually testing sites in different browser versions. Instead of having to maintain several VMs with older IE versions, developers can quickly preview layout, CSS, and functionality compatibility in one simple app.

Some key features include:

  • Simulates IE 5.5 to IE 11 on Windows 7, 8, and 10
  • Supports multi-tab testing for side-by-side comparisons
  • Includes developer tools for each IE version
  • Lets you switch between IE engines and user agent strings
  • Portable app with no installation required

Overall, IETester is an indispensable tool for web developers and testers who need to ensure their sites work properly in legacy versions of Internet Explorer. With its ease of use and ability to replicate different IE environments, it simplifies cross-browser testing and saves hours of configuration and maintenance time.
