The free version of Cloudflare is great! DDoS protection and CDN are completely sufficient and are a must for small sites.

I had been attacked before. After turning on Cloudflare's protection, the attack traffic dropped directly to 0, and the effect was immediate.

The Workers platform is so powerful that it can execute code directly on the edge and the response speed is very high.

Workers AI is online, running AI inference directly on the edge with very low latency!

Domestic access speed is still a bit slow, so it is recommended to use a domestic CDN.
