Supported TMS/variables include: - Google Tag Manager dataLayer variable - Adobe Launch rules and data elements - Adobe DTM page load rules and detection - Tealium data layer - TagCommander data layer - custom data layers (any variable represented as a JavaScript object) dataslayer supports multiple data layers / GTM containers on a single page, including those in embedded iframes. dataslayer also decodes and displays tags (including pageviews, variables, and click events) from: - Google Analytics (including Universal Analytics / analytics.js, dc.js, and ga.js) - Adobe Analytics / Omniture SiteCatalyst - Floodlight If you're using a beta or dev channel of Chrome, you can optionally enable blocking of captured tags to prevent data pollution.

  • (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 cornelissen: 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 Suter: 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
  • (2015-06-09) Brian Katz: Simply Great
  • (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!

  • (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.
  • (2018-07-02, v:0.10.15) Julie K': SLAYER
    How are you able to use Slayer's logo in your app???
  • (2018-02-26, v:0.10.15) Minli Xu: It is not showing sitecatalyst
    It is not showing sitecatalyst. But I have "sitecatalyst" box checked when installing. Why?
  • (2017-11-27, v:0.10.15) Kevin O'Connor: FireFox Quantum Support
    Would be great to have a version for FireFox Quantum using the WebExtensions API

    since the update of chrome to version 55.xxx it's not possible to enter the settings of dataslayer anymore. BTW: great work, DataSlayer is my most used extension ever!

    Since while ago Google Chrome supports themes in the developer tools but the dalaslayer don't uses those styles.

    Hi guys, The add on doesn't seem to be showing up next to the address bar.Tried uninstalling and installing it again, doesn't help. Any tips on making it work are welcome! Thanks Alex
