How it works
Set your bandwidth
Select your monthly bandwidth: 10 GB for a small site up to 100 TB for large-scale media delivery. Bandwidth is the primary cost driver for metered CDNs.
Choose your traffic region
US and Europe have the lowest CDN rates globally. If you serve Asia, LATAM, or the Middle East, metered CDN costs increase by 50-200% for those regions.
Filter by features you need
Need WAF? Edge compute? Image optimization? Filter to only show CDNs that include those features, and see which one costs the least.
