  About The Team

  
  

  Cloudflare’s Front Line (FL) group is responsible for maintaining and developing the main Cloudflare web server, processing over 100 million HTTP requests per second. In other words, we own the largest web server in the world.

  
  

  The Product Team is responsible for creating new customer-facing features, improving efficiency & safety, and building the next iteration of Cloudflare products. The platform is mostly in Rust, and most of our API is in Golang.
