isSPA is a free Chrome extension developed by Ören Aksakal. It falls under the category of Browsers and is specifically categorized as an Add-ons & Tools subcategory. This extension is designed to help users detect single page applications (SPAs) with ease.

Upon clicking the extension icon, users are promptly presented with an alert box displaying the mmcore status of the page. This feature allows users to quickly assess whether a webpage is a single page application or not. The mmcore status provides valuable information about the structure and behavior of the page.

One of the standout features of isSPA is its ability to visually indicate the detection of page changes without refresh. When the extension detects such changes, the icon turns red and displays the text "SPA". This intuitive visual cue allows users to immediately identify when a page is dynamically updating without traditional page refreshes, thanks to techniques like history push and pop states.

isSPA is a valuable tool for developers, testers, and anyone who wants to gain insights into the usage of single page applications. With its simple and straightforward functionality, this Chrome extension is a must-have for those working with SPAs.
