Zaraz use Workers to make third-party tools secure and fast

This post details how Zaraz, a third-party tool management platform, was built using Cloudflare Workers. It explains the challenges of traditional third-party script execution in browsers (performance impact, security risks, data privacy concerns) and how moving this execution to the edge with Workers provides benefits such as faster website loading, better control over data sent to third parties, and continuous verification of code integrity. The post highlights the specific requirements that led to choosing Workers (JavaScript execution, security, programmability, speed, global distribution) and demonstrates a basic Workers implementation for dynamically generating JavaScript.
