Handling 9B Daily Requests: Cloudflare Migrates cdnjs to Its Developer Platform
JeremyCMorgan · x · 2026-08-07
Cloudflare has completely migrated cdnjs, one of the internet's busiest open-source CDNs, to its own Developer Platform. Serving around 12% of all websites, cdnjs processes a staggering 9 billion requests per day.
This massive dogfooding exercise not only proved the readiness of Cloudflare’s platform but also surfaced critical limits when dealing with extreme real-world traffic. Consequently, Cloudflare raised the limits for Workers and Workflows. The engineering post details what breaks first when serverless architecture meets massive scale and the corresponding optimizations applied.
