On October 15, 2026, Cloudflare added a Forward action and Custom Functions to Cloudflare Gateway, running your own code at the exact moment a security policy makes its decision. If you maintain NGINX proxy pools for header injection or Logpush pipelines for alerting, replace them with a single Worker.

On October 9, 2026, Cloudflare made on-demand CPU and memory profiling generally available for Workers and Durable Objects, with interactive flamegraphs generated directly in production. Use it to chase memory leaks and hot functions instead of guessing from logs and aggregate metrics.

Cloudflare is absorbing Ryan Dahl’s Deno team and merging the workerd runtime with celld, Deno’s open-source implementation of Workers and Durable Objects released in August. If you want to run Worker-style apps on your own infrastructure, celld is now the path to watch.
