Identify web technologies
Wappalyzer is a technology profiler that shows you what websites are built with.
Find out what CMS a website is using, as well as any framework, ecommerce platform, JavaScript libraries and many more.
Wappalyzer is more than a CMS detector or framework detector: it uncovers more than a thousand technologies in dozens of categories such as programming languages, analytics, marketing tools, payment processors, CRM, CDN and others.
Install Wappalyzer for Chrome to find out the technologies used on websites you visit at glance.

- (2024-02-22) Даниил Пронин: I just watched a video while Chrome opened a new page and focused it just to show me “Wappalyzer has been upgraded”. You should never do that. Remove this function on extension updates.
- (2023-10-12) Eric P: Absolutely fantastic app. I cannot live without it.
- (2023-10-09) Игорь: не работает
- (2023-08-18) Tiến Thành Nguyễn (kKao4): amazing tool. tks
- (2023-06-27) Chris Lozeau: I wish I'd known this existed sooner!
- (2023-06-12) Walter VanRooyen: Nice tool, nice layout and design. But....This app should not be on all the time. It messes with mailchimp, it messes with Elementor/Wordpress, it messes with tons of sites and slows down or causes sites not to load. It should be like Builtwith, where you can click the app to see. Or like Google Tag Manager Assistant, where it doesn't load UNLESS you click it. This issue has made me uninstall it many times.

- (2023-05-20) xovu com: Nothing else compares and I've tried many different tech stack scanners using both website lookup tools and browser extensions. Pros: Besides Wappalyzer, no other tech stack scanner I've tried properly detects meta frameworks. For example, try scanning the astro.build website with the builtwith.com technology profile tool, it can't even detect the astro framework, pretty useless if you ask me! Some cool features about the Wappalyzer plugin I appreciate are: 1. ~~Ability to toggle the extension on and off from the Chrome Wappalyzer Icon~~ (see #1 Cons below). Update: this only works on individual websites. It needs to be global as I don't want the extension on all the time and to disable for each website is not practical. For this I'm removing two stars from my 5 star rating. 2. Use technology icon instead of Wappalyzer logo extension option. 3. Slick UI including Dark Mode toggle. 4. This plugin does not require you to signup and login unlike their website which does require you to signup in order to scan. Cons: 1. The biggest for me is that you have to manually disable this extension as the toggle switch from the pinned icon only works per site. Who wants Wappalyzer running all the time hogging up resources in their browser? I sure don't... Software Devs and Wappalyzer, if you read this, can you please consider making an easy way to disable this extension globally and not only per website? I do like to use this extension frequently, just not all the time (and yes, I'm too lazy to manage extensions and manually enable/disable Wappalyzer, that's a nuisance)... 3. Wappalyzer could do a better job at updating their CMS detection. For example, they didn't detect Directus, Payload CMS, Tina CMS or Strapi; but to their credit, they did detect Contentful, Storyblok, Grav CMS and even Page builders like Webflow & Elementor.
- (2023-04-26) Дмитрий (Git507): Приемлемая альтернатива WhutRuns, ставлю 4 из 5, поскольку изначальный замах на подписочную модель напрягает и настораживает.
- (2023-04-01) Nika Kerelashvili: best tool. top 3 needed when developing web
- (2023-03-29) Manoj Kumar: Thanks for the developer that they have made such a valuable extension to analyze any website.
- (2023-03-23) Gustavo Silva Pinheiro: É uma aplicação maravilhosa! Da para você saber quais tecnologias o mercado mais está usando para poder estudar. Agora, recentimente tem acontecido algo chato, que é quando você vai para o site a partir da extensão, a página do app é encolhida. Poderiam verificar?

- (2023-02-17) Ange Guillaume Koffi: Très utile !
- (2023-02-12) Doug Wilson: Functionally? Great, works well all around. Accuracy? Stellar, the signatures are good. Efficiency? This plugin is so bad I have a dedicated copy of Chrome for using Wappalyzer. The unbounded memory growth forces me to kill the process usually once a day if I use this on my regular Chrome browser. Disabling and re-enabling the extension is annoying. This would be 5/5 if you fix the performance OR give us ability to not run it at all unless clicked on (the 'on click' in settings is not sufficient).
- (2023-02-09) 林敬軒: Not working for Google and Youtube
- (2023-02-02) IANDS NoVA: The only web platform analyzer extension that works for me. Just pause any ad blockers while using it and it should work for many sites.
- (2023-01-18) Thomas Chereau: ça me mets bien les techno dans l'extension puis une fois sur le site de wappalyzer, le contenu de la page s'affiche pendant 2 sec puis le contenu disparait laissant place au footer qui prend toute la page..
- (2023-01-10) Michał Rzeszutek: Ostatnie wersje są wręcz nieużywalne. Powód jest prosty, widżet nawet się nie ładuje. Czas poszukać alternatywy.
- (2022-12-23) Youtube User: contain malvertising redirect me to smartredirect.de evidence https://i.imgur.com/QKLwfR4.png
- (2022-11-30) Simone Vacca: al momento non funziona su nessun sito (chrome macos)
- (2022-11-17) Hairul Lana: It's not working on my PC, the extension always saying "No technologies detected"
- (2022-10-26) Виктор Ефремов: начал периодически перекрывать сайты украинскими банерами :/
- (2022-10-24) The extension used to be pretty useful. However, a few weeks ago there was an update and now it shows no information whatsoever, regardless of the website I'm in. Sadly there are no other alternatives as good as this used to be.
- (2022-10-18) laburu agencia: No se que pasa ultimamente pero no me muestra los datos del sitio, llevo usandolo 6 meses pero ha estado fallando.
- (2022-10-11) jack: The idea is amazing but it says that every website is made with react? My PHP website: react My static plain html and css website: react My JSF Primefaces website: react Are you serious? I'd rather have a message "could not get all technologies" or something than just slap react everywhere. Another solution could be a percentage of how sure the extension is that a website is made with given technology
- (2022-10-05) Oleksandr S: Гарне розширення, що допомагає швидко "підглянути" які технології використовуються на тому чи іншому сайті
- (2022-10-04) Andrius: Great extension, so helpful when doing research about competitors
- (2022-09-06) David Constantine: Good app but after a while it uses an enormous amount of RAM even when not prompted to be used.
- (2022-08-12) Kevin Moore: The author is super responsive. Very useful for tracking the usage of our teck stack!
- (2022-08-04) Senior Programmer: I think it is excellent extension for developers. Thank you.
- (2022-07-27) Rinart (rinart73): It does the job but I can't keep in enabled all the time because it occasionally consumes 500MB+ RAM on its own.
- (2022-03-22) SANKALP RAUL: Very helpful
- (2022-03-16) Invalid account: used to work, but the company switched to a pay to play model, when you create technologys as a leader you really dont care about what the followers are doing
- (2022-02-26) David B: Doesn't work well. I switched to NerdyData instead
- (2022-02-21) Muhammad Adil Jabbar: very usefull extention.love to use.
- (2022-02-13) Steven Chan: Test
- (2022-01-07) surya singh: awesome plugin
- (2022-01-07) Bulat Z: with the extension enabled, pages fall with the Out of memory error
- (2021-12-31) Jack: love it
- (2021-12-20) Figar Ali: Thank you
- (2021-12-04) Heisenberge: idk why is this so good
- (2021-11-20) C K: The new version consumes huge amount of CPU. Works like bloatware.
- (2021-11-02) 花垣武道: 怎么修改语言 简体中文
- (2021-10-13) Albert Ronald: Such a great extension and working perfect on any site e.g; https://apkdice.com to detect the technologies on my sites. Didn't face any issue in it and using it for almost 8 years. I would recommend everyone who even wants to check the web technologies or frameworks used on a website.
- (2021-10-03) 창딩이: cannot detect https://www.tradingview.com/ or https://alphasquare.co.kr/
- (2021-09-29) N H: This is amazingly helpful
- (2021-09-13) Curtis James: 新版本不行了啊
- (2021-09-10) Somrat Sorkar: Dark Mode should be dark, not blue. And cache is doing so much problem. Need a clear cache button in the extension popup, not in the settings. by the way, you are doing a very good job. thank you
- (2021-09-07) Me: Useless
