The RUM Diaries: enabling Web Analytics by default

What this post added

Introduces the initial phase of a major upgrade to Cloudflare's performance analytics suite by combining Web Analytics with network-level insights. This will enable developers to pinpoint performance issues from the visitor's browser through Cloudflare's network to the origin, while preserving user privacy. Web Analytics will be enabled by default for all free domains on October 15, 2025, collecting client-side metrics like Core Web Vitals and resource load times. Data is aggregated at the edge to reduce storage and minimize latency, removing personal information. The platform aims to provide a privacy-first approach to performance monitoring and debugging.
