# Web Browser HMI Requirements

Cognex recommends opening Web Pages developed in Cognex Designer with the following browsers:

- Google Chrome™ browser, version 54 or greater
- Internet Explorer version 11

Note:

- For the best performance, Cognex recommends using Google Chrome version 54 or greater to view and interact with your Web-based HMI.
- Due to issues in Internet Explorer and Google Chrome, displaying HMIs in Web Browsers for a long period of time (multiple days) can result in the browser window being non-responsive or the browser crashing. Cognex recommends periodically restarting the Web Browser in this scenario.
