Latest reviews

  • (2021-11-24) Francisco Morales: Excelente herramienta!!! mejora el debug nativo de GTM, añade debug en AMP (desde GTM a estas alturas no es posible) y ofrece una serie de utilidades que harán tu vida más fácil, gracias https://www.thyngster.com un gran trabajo.
  • (2021-11-24) Ilpo Ryynänen: I use this tool at least weekly whenever I need to debug UA/GA4. Thanks David for creating it and I hope you continue improving it!
  • (2021-11-23) Carlos Gutiérrez: Best Chrome extension to debug GTM/GA. Great jobb
  • (2021-11-19) Analytics 1: The plugin I use everyday as someone working daily with Google Tag Manager and Google Analytics. Every agency should use this extension.
  • (2021-11-18) Gordon McCallum: It's a great extension, but the Nov update actually breaks GTM preview mode - doesn't track beyond the first page in the Tag Assistant. Please fix!
  • (2021-11-18) Dawid Maleszka: after the last update the debugging mode in GTM does not work properly. After turning off the plug, it is ok
  • (2021-11-18) Alfredo Mezquita: The new version is amazing. Fantastic work! It would be awesome if the extension would be able to preserve the configuration through navigation (tab selection and hit filters applied). E.g. You may want to debug only GA data so if you are in the GA tab and click on a web link, the new hit would be opened automatically in the GA tab and not in the GTM/GTAG tab (which is the default tab after each hit). The same with the filters at hit level. This would save a ton of time. Other than that, it's an awesome tool! Fantastic work!
  • (2021-11-17) Вячеслав Бибичев: Супер расширение, которое спасает жизнь и время :D Спасибо автору!
  • (2021-09-30) Filip Vidak: I know close to nothing about all this google analytics stuff and this is still easy to use and find what I need as a QA.
  • (2021-07-14) malikiz: dont work with localhost

  • (2021-06-03) Ed Sweeney: Thank you for a great plugin! Saves so much time and is super useful!
  • (2021-05-06) Anna Pisarenko: Расширение не работает(
  • (2021-04-22) Francois Gendronneau: Muchas gracias David for this tool! I've been using it from day one and now I use it every day! Sometimes the GA4 tab just keep on spinning but I guess this is more to do with the GA4 requests not being sent yet (sent in batch). Very well done :-)
  • (2021-04-07) Brian Foor: Doesn't work at all.
  • (2021-02-24) Michael Igor Popov: Best GTM and GA debugger. Thank you for making it!
  • (2021-01-06) Chih-Hsuan Fan: Best extensions for debugging GA-related tracking

  • (2020-09-27) Edward S: Excellent plugin! Much better than GA Debugger which I used to use. Now this is my go to plugin for auditing GTM.
  • (2020-09-21) Thomas Lerch: Deserves 5 Stars as it works like a charm :D I just went through all ratings and saw the 1 star rating. So I post a rating here to make up for the 1 star rating this plugin got undeservingly.
  • (2020-09-16) M M: Only works when it wants to. Will randomly open when the tag manager assistant is open but so far it's only done it once. Will not open on it's own. Trying to open using the tang manager assistant manually does nothing, then when clicking on the debug icon it just takes me back to this page.
  • (2020-09-07) Jose Tomas Rosales: Is it me or in the latest updates this extension is accessing chrome-search //local-ntp/local-ntp.html?
  • (2020-07-29) Kerem Beyazıt: Best plugin for GA.
  • (2020-07-27) Tom Parker: I'm sure it would be very good if it worked, but it stays on the hello page, with a 404 error for the driver.min.js.map file, tried on my desktop and laptop and the same for both.
  • (2020-07-08) Tobias Schmidt: My number one tool for debugging. While you can search for the GA collect in network, this is MUCH faster and more powerful.
  • (2020-04-12) Matt Michels: Easy to use, and great for testing and debugging!
  • (2020-03-17) Robin van Heukelum: The official Debug pane from GTM didnt work properly on my webpage. This thing does! This rocks!
  • (2020-03-13) Felipe V: I'm not able to make it work in Brave :( Just installed it and it says: "Hello! It looks it's the first browser session where you opened the extension. Don't worry we've got you covered, please just click reload button in your browser or press F5." But this message never goes away. I've tested it with no extensions and yeah, it seems like it is the browser itself.
  • (2020-01-10) Matt Latimer: Good tool for debugging GA calls but it crashes any Microsoft online SharePoint site. With the extension enabled online SharePoint will throw JavaScript errors and result in a blank page, disabling the extension allows them to load properly.
  • (2020-01-08) Diogo Da Silva: Can't work without it!
  • (2019-10-15) Zevent Kat: looks good but sadly I can't use it, each time that I try to use it my browser get broken with the "aw, snap!" message.
  • (2019-08-23) Dmitry Osiyuk: Very useful extension!) Thanks!
  • (2019-08-14) Great plugin. Can i buy a bear?
  • (2019-08-01) Banco Itau: Excellent extension. I've add a clear tag button though

  • (2018-09-06) Brian Clifton: There are a number of similar tools out there, but this is by far the most thought-through and comprehensive. Its in my toolbox and used regular. A huge time saver.
  • (2018-07-21) Markus Baersch: best plugin for debugging enhanced e-commerce implementations. love it :)
  • (2018-07-19) Drazen Ferencic: Great and useful extension!

  • (2020-09-22, v:0.3.2) Steve Bowsher: Export results
    Hi David, Firstly, I LOVE this tool - it's awesome and I pretty much use it daily. My suggestion (and it's probably been mentioned before or even already available?) is to have some sort of export functionality akin to the ObservePoint Tag Debugger. The reason for asking for this functionality is that when working with developers/engineers on implementation it's useful to provide them with a summary xls with what is and is not firing on each page of the site. At the moment I'm using the ObservePoint tool for this but I find your tool much easier and intuitive to use. Regards, Steve

    I see a discrepency between 'impressions' and 'add' EE events regarding how to data passed in Enhanced Ecommerce is formated in GTM/GA debug extension. For 'impressions' type EE data, the data is formatted in a table with a header including For 'add', the table is not showing, it's actually empty until I click "1" below, then the data shows in a table, but without any header. (makes it harder to know what columns is what data) Thank you for developing this nice extension by the way.

    Hello, in some cases I noticed that czech symbol š gets deleted by this addon. I noticed it in Trello card names and in Google Drive search box. The letter is deleted only on first and last position. For example i typ in Google Drive search box "šablona lešení aleš" (it means template and my name) hit enter and it becomes "ablona lešení ale". I tried disabling all addons and identified this one as the responsible. Im using Chrome on Win 10.

    Hello, I love your extension! I am mostly using it to debug GA calls, but it always (on every page load) jumps to first (GTM) tab, it would be great if it could remember the tab, so that I can click through a site and monitor GA events. Thanks!
