Discover what runs a website
A free browser extension that helps you identify technologies used on any website at the click of a button.
You may use the WhatRuns addon to find technologies used on each website you visit with just one click. We detect even new and forthcoming tools and services, ranging from developer tools and ad networks to WordPress Plugins and Themes.
Not only that, but you can also follow websites to get notified when they implement new technologies or remove old ones.
On the websites where it is utilised, every technology leaves a pattern. The WhatRuns algorithm recognises these patterns to determine a website’s tech stack.
Unravel a website, any website.
WhatRuns shows you pretty much everything that powers a website. Web apps they pay for, CDN they’re hosted on, how they track their visitors, WordPress plugins, fonts – you name it!
Follow websites and get notified.
Keep up with the pace by knowing when a website starts or stop using a technology. Follow websites, and we’ll notify you when that happens.
No sign-up required. Install and press the magic button.
