TrackLayer vs Google Tag Manager.

A free, powerful tag manager. Still fundamentally client-side. Still your responsibility to keep running.

GTM is the industry default — and for good reason. Free, endlessly flexible, every agency knows it. But it's a tag manager, not a tracking platform. You still build triggers, debug variables, fight the preview panel, and fix the bad tag that silently stopped firing in March.

OUR VERDICT

GTM if you have a dedicated tag manager admin. TrackLayer if you don't.

§ 02

When to choose which.

CHOOSE TRACKLAYER WHEN

→ You only have ad platforms and not a tag zoo

For Meta + Google + TikTok + Klaviyo, you don't need GTM's general-purpose tag engine. TrackLayer ships the 12 platform integrations ready-to-go.

→ You don't want to debug GTM preview mode

No triggers to configure, no variables to debug, no preview panel to stare at. The coverage heatmap tells you what's firing.

→ You want ad-blocker resistance

Client-side GTM is the #1 thing ad blockers target. TrackLayer's server-side ingest survives.

CHOOSE GOOGLE TAG MANAGER WHEN

→ You have a dedicated tag manager admin

GTM's flexibility is unmatched if someone on the team knows it deeply. TrackLayer intentionally removes that flexibility — which is a constraint if you want arbitrary client-side scripts.

→ You need 20+ custom event triggers with complex logic

GTM's trigger editor handles conditions TrackLayer doesn't expose. If your tracking needs are highly custom, GTM is the right tool.
