  • (2023-10-05) John Weiss: Awesome, but i wish they offered an "export", "save", or "print" feature.
  • (2023-09-24) Arsh: useless, not free!
  • (2023-06-06) Tyler Benson: This extension causes malware redirect hacks remove and uninstall. also it's went downhill anyway it used to be a really powerful tool
  • (2022-08-27) Fred B: Hi, I have this email where my address is ok for everyone.

  • (2022-07-08) DataPress: recommended
  • (2022-03-17) Mateusz Sikorski: iCloud "Hide my Email" is banned by BuiltWith Technology. Because they are greedy for your data and "uck" your privacy. I'm afraid so.
  • (2021-11-11) Paul Gray: Super useful extension!
  • (2021-08-11) Ian Miller: Doesn't work anymore. Asks to enter a Captcha, and there's no Captcha box. Clearing browser cache, restart device, nothing works.
  • (2021-07-27) Vince Aggrippino: Sometimes the BuiltWith extension just says "The website says we are forbidden to do a lookup on it."... What does that even mean? This is only supposed to show a concise summary of what's in _View Source_. There's no way to "forbid" that. Even when it shows information, most of its UI is devoted to upsell attempts. It's not even clear what they offer for the $99 price tag, but that's likely more than I'd ever pay for a simple browser extension.
  • (2021-05-24) Chris Morris: I wish it could default to the non-detailed report. I use it 3 times in a day and then I can't anymore because it defaults to the detailed. If it defaulted to the limited view, then the plugin would be more useful to me.
  • (2021-02-23) Lasse Nielsen: Used to love this addon, now it's just a cash grab.
  • (2021-01-13) Malikul Akbar: doesn't work, not load anything
  • (2021-01-07) Reza AB (ZenCode): It doesnt work anymore.
  • (2020-11-17) John Marra: I find that recently it reveals less and less. I tried to create a sign-on account and it won't accept Outlook accounts :-( So what email domains will it accept?
  • (2020-09-04) Volkan Yılmaz: Gerçekten harika bir hizmet ve büyümesini istediğim bir girişim. Teşekkürler.
  • (2020-04-03) David Haysom: Excellent tool
  • (2020-03-23) Weston Vincze: Awesome extension. Easy and quick to use.
  • (2020-03-19) Kai Carver: This extension used to work remarkably well for me, but recently it has been failing for me with the message: "The operation has timed out"
  • (2020-02-18) Frank: Basically unusable when every single time I click it they are asking for money to get any information. Worthless extension now.
  • (2019-12-15) Ahmed Mostafa: "Useless" Wappalyzer is beter
  • (2019-09-07) David Esau: I use this tool 500 times a day while prospecting for B2B companies that leverage Google Analytics and Adobe Analytics to generate leads for myself since our company built an API to both of those widely used tools that helps companies identify website visitors as companies based on firmographics. You can find me and more info at david (at) kickfire dot com. Best tool for prospecting based on techstack hands down. #accountbasedmarketing #techstack
  • (2019-07-31) Bensari Yasser: amazing tool for both marketers and web developer
  • (2019-07-19) Zane Koh: What does the dollar and the stop sign represent???
  • (2019-03-23) Faraz Ansari: Amazing....
  • (2019-01-25) Bucheron Rigide: 144$ par an pour détecter quelles sont les technologies utilisées sur un site web!!! C'est quoi cette arnaque??? Téléchargez plutôt Wappalyzer, c'est moins détaillé mais c'est gratuit et illimité!!!
  • (2018-11-23) Eka Susila: very very recommended extention ...
  • (2018-08-26) Zchary Ma: it really helps
  • (2018-08-03) Jc Cândido: very nice
  • (2018-08-01) Eric Scoles: Used to work adequately to give a reasonable guess at a site's tech foundation. Now, it's suddenly incomprehensible. This appears to coincide with some effort to monetize the platform by incentivizing login in some way that (like everything about this extension, now) remains abundantly unclear.
  • (2018-04-09) Danil Rogozhkin: kyl
  • (2018-03-20) Sri Si: Best extension - i used wappanalyze, page xray etc. but this is best 10x more details.
  • (2018-02-12) caue rego: ended up using other similar extensions which i consider simpler and easier / generally better, such as wappalyzer.
  • (2018-02-12) Otto Schneider: It's really good, but there are free extensions which does the same. Like 'Technology Checker' extension
  • (2018-01-11) Jimmy Túllume Salazar: Excelente herramienta
  • (2018-01-08) Jair Gutierrez: muy buena
  • (2018-01-06) Arif Abdullah: the best extension i have used so far..far better than wappalyzer..helped me a lot for development purpose...well done Developers keep it up!!
  • (2017-12-17) BIBIN JOHN: The best
  • (2017-11-28) Lahiru Liyanage: Good Tool to view technologies of the website
  • (2017-10-19) jkl542: Perfect extension for those who want to know what technologies are in use on any given website. Great for those who do website security. This is by far the best I have ever used. Beats the heck out of Wappalyzer.
  • (2017-09-10) PubliKanguro Tecno - Marketing: Excelente herramienta para espiar a la competencia!
  • (2017-08-24) minh châm: great!
  • (2017-08-23) Excelente y práctica
  • (2017-07-19) Cristian Dobrescu: Doesn't work on intranet. Other extensions of this type work just fine.

  • (2017-06-05) Marshall Parker: Great extension.

  • (2021-12-20, v:3.4) Leo Nellessen: Technology in use tab, and meaning of certain symbols
    To the far right of where technologies being used is displayed (after first detected & last detected) I often see a dollar sign ($) and/or another symbol (i.e., ink drop icon/symbol), but can NOT find out what they represent- anywhere on your website or anywhere else on the web.

  • (2021-02-24, v:3.3) Ryan Trudell: Paid version of Builwith not working
    Hello - I've used the paid version of Builtwith for the past 6-9 months without a single issue. In the past 2-3 weeks, it's been extremely buggy and loads <10 % of the time I turn it on. I'm " " close to purchasing Wappalyzer as that functions just fine on my Chrome browser.
  • (2021-02-23, v:3.3) Errin Tamari: wont load

  • (2021-02-23, v:3.3) William Rice: Won't load

  • (2017-04-27, v:2.6) Chris Robichaud: Leave info on screen
    When the popup is open and you switch to a different application it closes, which is annoying if you are trying to make notes. Maybe you could change the behavior or add an option to open summary in new tab?

    The plugin is not loading page info anymore. I used this plugin quite a bit; sad to see it not working. Hope it gets fixed soon...
  • (2017-03-01, v:2.5) Plugin appears to be broken
