Why serverless edge matters in a privacy-first world
As third-party cookies disappear and privacy regulations tighten, advertisers need new ways to maintain campaign performance without sacrificing compliance. Cloudflare Workers make it possible to run serverless code at the CDN edge, responding to requests locally and respecting user consent.
This edge-first approach helps businesses reduce latency, improve privacy, and adapt to the post-cookie era.
Introducing Blotout
Our first product built with Cloudflare Workers is Blotout. Blotout lets you send consented data directly from your domain to the Facebook Conversion API. Setup takes just two minutes and results in an average 30% increase in leads.
This is a game-changer for marketers who have struggled with pixel reliability after Apple iOS changes and Firefox’s tracking protections.
How Blotout leverages Cloudflare Workers
Blotout uses our patent-pending technology that transforms and replicates data at the CDN edge. With Cloudflare Workers, we can:
-Run lightweight microservices directly at the edge
-Ensure consent-based signal delivery
-Provide fast performance (sub-3ms pixel delivery)
-Deploy instantly via the Cloudflare App Store
In short, EdgeTag enables privacy-first marketing infrastructure without the need for complex server-side engineering.
Benefits for advertisers and developers

The road ahead: Google Conversion API and beyond
