CloudFlare’s pricing is based on features rather than how much bandwidth you use. CloudFlare operates out of 28 data centers around the world and uses a technology called Anycast to route your visitors to the nearest data center.
CloudFlare doesn’t charge for bandwidth usage on the basis that if your site suddenly gets popular or suffers an attack, you shouldn’t have to dread your bandwidth bill.
According to CloudFlare, on average a website using the CDN will load twice as fast, use 60 per cent less bandwidth, have 65 per cent fewer requests, and is more secure.
Pricing: Free to use (with limited features). Paid plans start at $20/month for your first website and $5 per month for each subsequent website.
