IETester is a desktop testing browser for checking how websites render and run scripts in different generations of Internet Explorer. It provides rendering and JavaScript engines from IE5.5 through IE11, plus the Internet Explorer engine installed on the computer, within one application. Developers can compare pages across engines when maintaining legacy sites or investigating browser-specific problems. Some features are limited, including file inputs, Java applets, alert and confirm dialogs, and window.open behavior.

IETester is a desktop browser tool for web developers and testers who need to inspect how pages behave in different generations of Microsoft Internet Explorer. It brings multiple Internet Explorer rendering and JavaScript engines into one application, so a site can be checked against older browser behavior without switching between separate browser installations. The available engines range from IE5.5 through IE11, alongside the Internet Explorer engine installed on the computer.
Each engine can be used to open web pages and examine their rendering and script behavior. Comparing the same page across engine generations helps identify differences in layout, styling, or JavaScript support that may affect users of older Internet Explorer versions. This makes IETester useful when maintaining legacy websites, testing compatibility changes, or investigating reports that a page works in one browser generation but not another. It is intended as a testing aid rather than a general-purpose browser for everyday browsing.
The application runs the different engines within the same process, allowing testers to access several browser generations from one desktop tool. Its scope centers on rendering and JavaScript compatibility; the provided feature set does not establish broader tools such as automated test suites or developer debugging panels. Some browser behavior is incomplete: Previous and Next navigation and focus handling may not work properly, while JavaScript alert and confirm calls do not function correctly. The window.open method also returns null instead of the newly created window.
Some page features have additional limitations. File inputs do not open a file-selection dialog, and Java applets are not supported. Flash does not work in the IE6 instance when running in user mode, and CSS filters may also fail in user mode; running IETester as an administrator is noted as a workaround for those two issues. These restrictions matter when interpreting test results, particularly when a site depends on dialogs, file uploads, applets, Flash, or legacy CSS effects.
IETester is freeware for personal and professional use. It is intended for Windows environments, with support listed for Windows XP, Vista, 7, 8, and 10, including the specified 64-bit editions. It is most useful for compatibility checks on sites that still need to account for older Internet Explorer engines, but its documented limitations mean that results should be verified in the corresponding browser environment when accuracy is critical.
