Description from store 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.

  • (2022-01-13) summer2019: Не определил популярную CMS - XenForo Можно сразу сделать вывод, насколько это "профессиональное" расширение
  • (2022-01-04) Tadas Talaikis: Error handling response: TypeError: self.processResponse is not a function at chrome-extension://cmkdbmfndkfgebldhnkbfhlneefdaaip/js/notification.js:154:10
  • (2022-01-03) Jamie Lincoln: Used to be great but no longer works.
  • (2021-11-09) Angel Vazquez: Dejó de funcionar / Stopped working
  • (2021-10-13) Manuel Burghammer: Keine der Angaben stimmt. PHP 5.3 anstatt 7.4, CMS Typo3 anstatt WinterCMS, JqueryUI wird gar nicht benutzt aber angezeigt. Dann noch Webserver falsch, Plesk falsch, kein Bootstrap .... Kurz gesagt, alles falsch, daher unbrauchbar. Die Erweiterung war echt mal super, das ist leider vorbei
  • (2021-09-13) Wee Zheng: not works anymore, removed it and use back Wappalyzer; Wappalyzer works fine for me.
  • (2021-08-24) Daniel: I guess it doesn´t work any more at all. I tried it with 2 different websites, one that was relaunched in March 2020 from another CMS to wordpress and one that has been set up entirely new in summer of 2020. With the first website it shows NOW the data from before relaunch and with the newly setup website it doesn´t show anything else than the spinner. With other sites that already have been longer online it shows also some data, I guess it is also old cached data. What runs what runs?-> Old data. I just wonder if this is so, why they still keep it online. I cannot see any good and legit reason. My recommendation: delete the extension immediately.
  • (2021-08-24) David Baker: It used to work all the time, but now it is just showing the spinner and not coming up with anything for many websites. It is hit or miss.
  • (2021-08-17) Ana Garita: Por qué a veces funciona y a veces no? cuando funciona es genial la información que da, pero no entender por qué no funciona a veces le quita funcionalidad
  • (2021-08-10) Dominik Vodárek: Stopped working

  • (2021-05-28) Samuel Odey: It's amazing that I can get a synopsis of any site I want without any hassle. Great extension.
  • (2021-05-17) Souvlaki42: Very good and works on Google Chrome & Opera Chromium too. The only bad is that a few times doesn't find the server software right!
  • (2021-05-15) ux net: Hi and thanks for your incredible extension I wanted to know how can i hide my theme from whatsrun? is there any way to do that? thanks in advanced
  • (2021-05-09) David Darcy: Honestly, its ok. While it provides good info on what runs a website, it is lacking in some of it. For example it wont detect certain js frameworks if they aren't very popular. You are better off just looking at sources in the dev tools.
  • (2021-04-24) Photik: Loved using it until it stopped working, maybe a recent update. Currently using other alternatives while we wait for it be fixed. :)
  • (2021-04-18) Fung Wai Shing: Great for wordpress sites. I use it together with SimilarTech Prospecting.
  • (2021-04-01) Joe Dodman: Just Loads forever
  • (2021-03-31) Djno0dle: Used to work. Now it just shows the loader with no results.
  • (2021-03-27) DAJANA MAR: super tool
  • (2021-03-23) Leo Liang: Used to work well, but not any more. p.s. latest version.
  • (2021-03-17) Blostex: Porque en algunas paginas web la extensión no funciona?
  • (2021-03-10) Fasih ur Rehman: It used to work great but its been a few weeks now its continuously giving maintenance error or just loading. Can't use it anymore. Sorry
  • (2021-03-08) 竹子貓: Good for me to learn about how to build a good website
  • (2021-02-26) Kuldeep Ravishankar: Loved it!
  • (2021-02-19) Fred B: Does not work, very slow and server down frequently.
  • (2021-02-16) Anubhav Bhatnagar: There servers are always down i guess...
  • (2021-01-31) Мистер. Jrx: Excelente extensión me muestra todos los detalles que quiero saber de alguna pagina web.
  • (2021-01-28) Bret Wagner: 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.
  • (2021-01-25) Charlie Hayes: I caught it using 100% CPU
  • (2021-01-22) njpromethium: it loads forever.. even if it does, only a few technologies are detected so it's not useful at all.
  • (2021-01-18) Luqman Khan: It just keep loading and never show results.
  • (2021-01-06) Raiyan Sarker: Used to be good, now it became useless!
  • (2020-12-15) Elevation Allah: 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.
  • (2020-12-11) Helene Houston: 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.
  • (2020-11-27) Dion Wiggins: 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.
  • (2020-11-10) Kağan Akbaş: Works maybe 10% of the time. Otherwise it gives either a "Server Upgrade" error or blank screen. Shame.
  • (2020-11-03) Derek Lam: Usually not work
  • (2020-10-05) Sam Frost: Used to be great, but now always saying 'server upgrade' and often totally offline.
  • (2020-10-03) damjan postolov: COOL
  • (2020-09-30) tiara oliva: me parece muy buena
  • (2020-09-21) Emre Sert: garbage. it keeps giving me server maintenance warning and it shows only the basic shopify extensions not the 3rd party apps.
  • (2020-09-07) Andres de Lucca: Not working - last update Jan-2020 but it hasn't been working for a while, don't understand
  • (2020-08-28) Ramsey Rama: excellent helped me make 170,000 $ after learning top technologies
  • (2020-08-20) Bene Tamás: 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.
  • (2020-07-31) Wagner Cateb: Very nice tool!!
  • (2020-07-23) Lewis Edgar: 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.
  • (2020-07-14) Robi Json: can you support vue?
  • (2020-07-02) Tomas Echeverri: Almost no info compared to Wappalyzer. I'll keep using Wappalyzer.
