Cloudflare acquires Zaraz to enable cloud loading of third-party tools

This post announces the acquisition of Zaraz and the launch of Cloudflare Zaraz (beta), a product that manages and loads third-party tools in the cloud. It addresses the problems of third-party bloat, performance degradation (average 40% slowdown), and security/privacy risks associated with traditional tag managers. Zaraz aims to improve website speed, privacy, and security by running third-party scripts in the cloud instead of the browser. It offers backward compatibility with Google Tag Manager's dataLayer and includes a library of 18 third-party tools. The post highlights Instacart's success with Zaraz, achieving 0 ms Blocking Time and increased security by proxying requests through their own subdomain using Cloudflare Workers.
