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.
FAQ
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.
Good for me to learn about how to build a good website
Loved it!
Does not work, very slow and server down frequently.
There servers are always down i guess…
Excelente extensión me muestra todos los detalles que quiero saber de alguna pagina web.
Used to be great, not sure if they’ve taken the service down or what’s going on, but the extension never loads details now in the last several weeks (possibly months). Time to remove.
I caught it using 100% CPU
it loads forever.. even if it does, only a few technologies are detected so it’s not useful at all.
It just keep loading and never show results.
Used to be good, now it became useless!
This plug in a network bandwidth vampire. I’ve seen my bandwidth throughput go from 50mbps to 8 kilobytes per second.
This plugin should not be on the store because it’s really malware or a trojan or rootkit.
This is not legit software.
Used to love using this plugin to aid me in doing website audits for clients before they allowed me access to the backend, but now it no longer appears to be working at all… Very disappointing.
Utter rubbish. I switched from one platform to another on our site about 5 months ago. It is still listing the old sites technology. I have a new support site and the best it can do is tell me the fonts used. Even the most basic tools can tell you so much more and work it out in near-real time. Ignore this piece of junk and try other tools such as https://builtwith.com/ that give you real data.
Works maybe 10% of the time. Otherwise it gives either a “Server Upgrade” error or blank screen. Shame.
Usually not work
Used to be great, but now always saying ‘server upgrade’ and often totally offline.
COOL
me parece muy buena
garbage. it keeps giving me server maintenance warning and it shows only the basic shopify extensions not the 3rd party apps.
Not working – last update Jan-2020 but it hasn’t been working for a while, don’t understand
excellent helped me make 170,000 $ after learning top technologies
This extension gives an awesome insight into how many third party javascript code is launched on every web page. When using the ScriptSafe extension, then you can easier decide wether to allow scripts from third party or not. This extension helps provides more information about this party scripts and based on that you can make a decision in ScriptSafe extension.
Very nice tool!!
Not 100% reliable due to ongoing server maintenance making thee extension completely useless. However, when the extension is working it works perfectly and is a great addition to any browser who deals with dev work – but I cannot fully recommend it.
Almost no info compared to Wappalyzer.
I’ll keep using Wappalyzer.
