Me Encantaba el logo de Slayer como identificador de la extensión. Es una Herramienta Genial y simple!!!
i spent all day to find this extension. It works!
This is a must have ! I recommend it to my colleagues and clients :)
This dataLayers analyzer is unreadable and columns are too mashed
Really easy to use. Helpful tool for quickly confirming which events are sent with GTM.
We just identified an issue where this extension sometimes stops analytics tags from firing for Adobe Launched.
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!
Works well with Tealium
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.
nice and very helpful
