konami2popup is a free Chrome extension developed by Mark I Weightless Industries. This extension pops up a page when a Konami command is entered. With konami2popup, simply enter the famous Konami code ↑↑↓↓←→←→BA on your keyboard to trigger a pop-up of the currently open site in the specified screen size.

This extension is particularly useful for web developers who want to check how their site looks on a specific screen size or for those who want to practice typing the Konami code. Additionally, you can also pop up the site without using the Konami code by accessing the extension's context menu.

It's worth noting that if the Konami code does not work initially, you can try again after reloading the page. Rest assured that the extension only monitors keystrokes to determine code matches and does not send any keystroke information to external servers or record it internally.
