WhatRuns extension is one click away for you to find technologies used on any website you visit. From Developer Tools and Ad Networks to Wordpress Plugins and Themes, we detect even the new and upcoming tools and services.

Not just that - you can follow websites so that you get notified when they use new technologies or remove existing ones.


How do you know what runs a website? Every technology leaves a pattern on the websites it is being used. WhatRuns' algorithm recognizes these patterns to detect the tech stack of a particular website.

What all things you identify on a website? WhatRuns detects almost everything that runs a website - frameworks, web technologies, CMSs (and its plugins), themes and fonts to name a few categories.

How is WhatRuns different from extensions like Wappalyzer, BuiltWith, Datanyze and Ghostery? While all of these are good old products, WhatRuns is less heavy on your browser, has a better detection accuracy and recognise even the latest technologies and plugins compared to our counterparts. We also uncover fonts, Wordpress plugins and themes used on websites, which nobody else does at the moment.

Hello, I hope you're having a splendid day! I am currently seeking opportunities to expand my business operations by investing in extensions with a significant user base, beginning from 50,000 users and up. No matter if your extension has a modest user base or counts its users in the millions, I am interested and ready to negotiate a purchase. If you are in possession of such an extension and looking to turn it into a profit, please consider reaching out to me. We can discuss the price and proceed with a transparent and secure transaction through a trusted escrow service based in the United States. It's great that Google allows the transfer of extension ownership between accounts, so your Google account ownership will remain intact. If you have any needs, please contact us via the following contacts Whatsapp: +1 (248) 896‑8035 Telegram: t.me/harryysandersonn
