Latest reviews

• (2023-11-30) Joe Marshall: Lets you see events from previous sessions, which is what I needed it for.
• (2022-05-02) sammy boy: if its got a Slayer background image, it worth it
• (2022-03-28) Bogdan Nazaruk: The interface is really awkward. It would be nice to rework how the data is presented. Becomes hard to work with. But the backend is amazing. Just looked through the source to see how it gets all DEs. _satellite._container.dataElements Pretty cool. Didn't realize _satellite gave access to all DEs.
• (2021-11-26) Steven Carr: Works great! Easy to use and allows you to see quickly what's happening with your tagging and data.
• (2021-10-28) René Arias: Me Encantaba el logo de Slayer como identificador de la extensión. Es una Herramienta Genial y simple!!!
• (2021-09-23) Alex Moore: i spent all day to find this extension. It works!
• (2021-08-11) Fanny Péraudeau: This is a must have ! I recommend it to my colleagues and clients :)
• (2021-06-08) Dan Anderson: This dataLayers analyzer is unreadable and columns are too mashed
• (2021-04-07) Margaret Shelman: Really easy to use. Helpful tool for quickly confirming which events are sent with GTM.
• (2021-03-02) Besir Redzepi: Love it!
• (2021-02-24) Tim Bolle: We just identified an issue where this extension sometimes stops analytics tags from firing for Adobe Launched.
• (2020-11-29) Brian Katz: Simply Great Wow! I originally rated dataSlayer in 2015 I've found it indispensable all this time
• (2020-08-26) Matthias Borchert: Hi this is so useful, thank you! Will it also cover App+Web Analytics soon? A+W is already very important in our daily work. Thanks!
• (2020-06-25) Ondřej Šubrt: I cannot imagine my work without this great tool... I am using it every day and it really simplify my work. Thank you for that I will promote It everywhere I can.
• (2019-09-13) Worked great for my purpopses
• (2019-08-22) Thomas Culetto: Works well with Tealium
• (2019-08-15) James Buckley: Sometimes using the GTM Preview mode feels a bit overkill for checking if some data layer push events or Google Analytics tags are present, which is where this extension comes in. It's an incredibly useful, no-nonsense tool which I always recommend to others when working with GTM.
• (2019-05-15) Daniel Valide: nice and very helpful
• (2018-10-15) Eu Gen: Please add "- adds advertisement to google search results" to the feature list! Otherwise it stays a secret feature and no one will ever know this nice feature exists.
• (2018-05-01) Alistair Johnstone: Use this all the time for debugging GA and GTM
• (2017-12-28) Timothy Smith: Perfect for testing any on site Google Analytics events or Google Tag Manager configurations. Easy to work with interface and very accurate.
• (2017-11-14) Nick Guebhard: Much more accurate than GTM Preview and Debug mode. Thank you!
• (2017-10-20) Aitor Alejandro: Sencilla y práctica. Para poder observar el objeto dataLayer de forma visual sin necesidad de inspeccionarlo a través de la consola.
• (2017-03-17) Paul Cikatricis: It's wonderful but recently it has stopped working on my local dev site. It's showing the GTM instance but not the GA. The same code works and shows just fine on production site. Not sure what this might be as it worked perfectly before and I don't recall changing anything. Other GA debugging tool called 'GA Debugger' still works fine. Otherwise a really helpful tool.
• (2016-12-08) Ajinkya Mhatre: simply superb!
• (2016-10-04) Kevin c: Very useful
• (2016-10-03) Alessandro V.: Not always trustful. In general a usefool tool, but right now we experience some discrepancies between dataslayer vs GTM-debugger and where dataslayer missed some important parts, which was misleading when testing.
• (2016-08-29) Rhian Lewis: Really useful - thank you for this!
• (2016-07-19) Phil Bergdorf: thanks for this!
• (2016-04-08) Anton Kharlamov: really helpful!!! plus one
• (2015-11-19) Kiril Kirov: This extension really helped me, clean and simple, amazing!
• (2015-10-14) Aleksey Oblozhko: looks like the only plugin to check GTM Events that is done well
• (2015-07-02) Eric Matisoff: I like this extension because it requires less clicking to view page load tags - very nice. The only thing it's missing is the ability to capture onClick tags, which is a pretty big miss. Hopefully the dev is working on this now :)
• (2015-07-02) mannbarry2: love it
• (2015-04-14) Rutger Meekers: Very good! Finally an extension with the possibility to visualise the CEDDL dataLayer (digitalData).
• (2015-03-27) Anton Abreu: Very helpful.
• (2015-02-23) Andrew Kerr: Great tool to save time when testing tagging specs, thanks!
• (2014-10-05) Cornel Coman: Great tool!
• (2014-08-12) Paul G: A very good extension, even if it doesn't handle two different dataLayer on the same page :-(

• (2023-06-08, v:1.5.1) Duoplus Team: How to view datalayer events for events ajax form submissions
  When I use Dataslayer it only seems to show the datalayer events on the initial page load. When I submit a form that is submitted with ajax, dataslayer doesn't provide any information about the datalayer events that happened during the form submission. Is there any way to view the datalayer events for ajax form submissions?

• (2022-04-20, v:1.5.1) Leah Ferguson: Dataslayer not working
  Hello - I've noticed dataslayer is not working consistently for the past couple of weeks. Could this be because I've updated to a new version of Chrome?
• (2022-04-18, v:1.5.1) Ben Claflin: Dataslayer no longer appearing on some sites

• (2022-03-23, v:1.5.1) Eric King: Edge
  Any chance of getting this added to Microsoft Edge add-ons since it is largely Chrome driven now? Also, I may undertake trying to get approval to use this inside my company's network. I am not sure if they reach out to the developer if they do that or not but they may.
• (2022-03-22, v:1.5.1) Megan Deppen: Dataslayer removed from chrome developer tools
  Dataslayer is not appearing in chrome developer tools even though it is added as a chrome extension. I have tried removing it and re-installing.
• (2022-03-18, v:1.5.1) 문찬기: serverside

  hey guys, When I loaded up dayaslayer it just had the url with a red 'x' next to it but I tried the same website yesterday and it worked. Do you have any troubleshooting advice? I re-installed the plugin but got the same result. Thanks! Tom
• (2021-03-19, v:1.4.0) Kevin Gutierrez: VM326:82 Uncaught (in promise) TypeError: Cannot read property 'then' of null
  I'm getting an error in some sites: Seems like in some cases let cleanValue = window._satellite.getVar(elementName); returns null as typeof null is also object, it would be good to validate that case: ``` if ( cleanValue !== null && typeof cleanValue === 'object' && typeof cleanValue.then === 'function' ) ```
• (2021-02-23, v:1.4.0) World Vision New Zealand: Events Not Showing Up
  Hi there, My colleague and I both have Dataslayer. When clicking on the same element on the same webpage, I am seeing the event catagory, action and label, but she is not. Our settings look the same. What does she need to do in order to see events? Thanks.
• (2020-11-16, v:1.3.0) Валерия Нечаева: Pageview display problems
  The data on the google analytics counter has ceased to be displayed. There is data about events, but there is neither the fact of sending a pageview, nor custom parameters. The problem is observed for analytics.js
• (2020-08-26, v:1.3.0) Matthias Borchert: A+W Support
  Hi! Will the dataSlayer support App+Web Analytics soon? This would be perfect. Thanks for your great work!
• (2020-06-26, v:1.3.0) Trevor Rapp: dataSlayer disappearing
  I have been having problems where dataSlayer will be showing up in my Chrome console, but then suddenly disappear or become invisible. Really love the tool, but it's starting to become inconsistent and unreliable.
• (2020-06-17, v:1.3.0) Brian Katz: dataSlayer not appearing in Chrome Dev Tools
  Thank you for dataSlayer Using Version 83.0.4103.106 (Official Build) (64-bit) on Windows 10 (Version 10.0.18363 Build 18363 - just updated twice in the last 2 days) Console shows "** dataslayer: injecting Launch monitors **" but dataSlayer does not appear - regardless of site
• (2020-06-08, v:1.3.0) Kacper Czubak: Invisible spaces
  Spaces are invisible in variables - there should be a mark where a variables holds a value with space in the beginning or in the end.
• (2020-06-08, v:1.3.0) Kacper Czubak: Dataslayer not showing up in console
  Since last update i have to open console and dataslayer before I open the webpage. Opening a webpage and then going to console makes dataslayer invisible.
• (2020-02-05, v:1.3.0) Jannette Pazer: Dataslayer not showing events triggered again
  Been using dataslayer for over a year, love it, but in some recent testing, I'm seeing events being triggered in the GTM preview box, but not showing up in dataslayer. I think I've narrowed it down to when I click a button that triggers an event (which I can see in GTM preview and in dataslayer), and then repeat the same action (and it shows up in preview but not in dataslayer). Or an action that takes me to a new page, hit the back button, and the 2nd time I do that action, the event shows in GTM preview, but not in dataslayer. Any idea what could cause this? Thanks!
• (2019-12-18, v:1.3.0) Bharti Yadav: What is the meaning of Join ID?
  When we checked analytics code process using data slayer - we get a 9 digit number called 'Join ID' - what does this mean?
• (2019-03-05, v:1.0.1) Release 1.0.1 - Variable Naming Option
  Amazing tool and great update. It would be really helpful to have an option to set the variable naming for the GA hits. e.g. Friendly naming e.g. "Document Location" or the actual variables names as on the network hit. e.g. "dl".
• (2019-02-07, v:0.10.15) Red cross
  Why with dataslayer I can see som hit I can't see in the browser console > Network ? These hit in Dataslayer have a little red cross and is a little lighter than a hit where we can see in the browser consoler > Network. Thanks
• (2018-10-25, v:0.10.15) Martin Vinter: Search function
  Hi Sean, Thanks for a great tool. I use it every day - love it :o) The list of variables can be quite long at times. It would be really nice with a simple search- or even better, a filter-function similar to the one that can be found elsewhere in the Chrome debugger.
