Platform apps blue
Build new applications on our serverless platform.

Create entirely new applications or augment existing ones without deploying infrastructure. Based on an isolate rather than a container model, there’s no need to select regions, manage scaling, or pay for capacity that you don’t use. Cold start times are eliminated, and your code runs across every data center in Cloudflare’s network, which is milliseconds away from virtually every Internet user.
