CloudFlare protects and accelerates any website online. Once your website is a part of the CloudFlare community, its web traffic is routed through our intelligent global network.
We automatically optimize the delivery of your web pages so your visitors get the fastest page load times and best performance. We also block threats and limit abusive bots and crawlers from wasting your bandwidth and server resources. The result: CloudFlare-powered websites see a significant improvement in performance and a decrease in spam and other attacks.
CloudFlare designed its CDN (Content Delivery Network) without the legacy of the last 15 years. Our proprietary technology takes advantage of recent changes to hardware, web server technology and network routing. In other words, we’ve built the next-generation CDN. The result is a CDN that is easier to setup, more affordable, and performs better than any legacy CDN you've tried before.
No configuration necessary
You do not have to spend time designating which files to cache. CloudFlare’s technology builds the cache for you based on your traffic and what objects on your site are safe to serve from the edge.
Works with static and dynamic content
If your server ever goes offline, CloudFlare will serve a limited copy of your cached website to keep it online for your visitors. CloudFlare builds the Always Online™ version of your website, so your most popular pages are represented.
Protect against traffic surges
If you get a surge in traffic, CloudFlare’s CDN will absorb the effect so your server stays online. On average, you'll see 65% fewer requests to your servers and save 60% of your bandwidth, even with CloudFlare's free plan.
Rock solid reliability. With CloudFlare’s distributed network, if there is an issue in one of the data centers, visitors to the other data centers are unaffected. If the issue persists, our system can easily reroute visitors to the next closest data center. The end result is a seamless experience for your visitors. Check out our network map to learn more.
Works with other CDNs
If you’re already using a CDN, CloudFlare works as a complement. You have the choice of routing CDN traffic through CloudFlare first (saving you bandwidth & money) or bypassing CloudFlare altogether for your CDN traffic.
