All your data in one place.

TAGGRS collects, enriches, and distributes consented first-party data through Server-side Tracking.

See the events the browser would have lost

Your tags send events to your own subdomain first. Ad blockers and browser restrictions no longer drop them before they reach Google and Meta.

Optimize your campaigns and ROAS with clarity.

Consent travels with every event
