Azure Front Door vs KeyCDN

The short answer
- Pick Azure Front Door if
- Teams on Azure that want CDN, global load balancing and WAF as one combined entry point rather than separate products.
- Pick KeyCDN if
- Low-commitment testing or small sites — no free tier, but the $4/month floor and no-commitment billing make it cheap to try against real traffic.

Consider something else if…
- Azure Front Door: Budget-sensitive at small scale — no free tier and a $35/month base fee before any traffic is a higher floor than most pay-as-you-go CDNs in this category.
- KeyCDN: Bandwidth volume is large — $0.04/GB is the highest entry-tier bandwidth rate of the CDNs sourced here for North America/Europe.
