Cloudflare built Pingora, a Rust‑based HTTP proxy that processes over a trillion daily requests, to overcome Nginx's architectural limits, achieve higher performance, lower resource usage, and add features unavailable in the legacy stack.
Cloudflare has open‑sourced Pingora, a high‑performance Rust asynchronous multithreaded framework for building HTTP/1 and HTTP/2 end‑to‑end proxy services, detailing its features, runtime capabilities, and the company’s motivation to promote memory‑safe infrastructure while noting its pre‑1.0 status and limited OS support.
Cloudflare built Pingora, a Rust‑based HTTP proxy that processes over a trillion daily requests, delivering lower latency, higher connection‑reuse, and up to 70% CPU and memory savings compared to Nginx, while adding extensible features and stronger memory safety.
Cloudflare abandoned Nginx for its own Rust‑written Pingora proxy to overcome performance, scalability, and feature limitations, achieving higher throughput, lower CPU and memory usage, better connection reuse, and enhanced security while supporting non‑standard HTTP use cases and enabling faster feature development.
Cloudflare's top architects explain why they replaced Nginx with the Rust‑based Pingora proxy, detailing architectural limits of Nginx, design decisions, performance gains, resource efficiency, and new capabilities that make Pingora faster, more efficient, and safer for massive internet traffic.
This article explains how Cloudflare replaced NGINX with Pingora, a Rust‑written HTTP proxy that processes over a trillion daily requests, offering superior performance, efficiency, and security through a multithreaded design, custom HTTP library, and programmable request lifecycle.
The article explains Whistle, a Node.js‑based cross‑platform HTTP proxy, by first showing a simple proxy implementation and then detailing its full architecture—five core modules for request entry, tunneling, processing, rule management, and plugin handling—along with its extensible, isolated plugin system.
