Code Everywhere: Why We Built Cloudflare Workers

The speed of light limits latency in internet applications, but Cloudflare's network of 117 data centers has reduced this by moving closer to end users. However, the code that makes these applications work is still located on servers or devices. Cloudflare Workers aims to create a third place where code can run: neither on the device nor in the backend server. This approach allows for faster and more efficient applications by reducing latency between users and servers. The platform enables developers to write JavaScript code that runs on every single one of Cloudflare's servers worldwide, allowing for instant updates and multiple versions available for testing and deployment.
