CloudflareSpeedTest is a utility that finds the fastest Cloudflare server IP address for your specific location. Cloudflare is a global network (called a CDN, Content Delivery Network) that many websites use to serve their content faster. However, Cloudflare has thousands of IP addresses across the world, and the one automatically assigned to you might not be the quickest option from where you are. This tool runs a speed test across a large range of Cloudflare IP addresses, measures both the latency (how quickly each server responds) and download speed, then presents you with the top performers ranked by speed. The README is primarily in Chinese, reflecting its audience, users in China in particular often experience poor performance with the default Cloudflare IPs, so finding a faster one makes a meaningful difference. For a founder or developer who has websites behind Cloudflare, this tool isn't something you'd typically run yourself, it's designed for end users who want to manually configure their network settings to route through a faster Cloudflare node. This is more of a power-user networking tool than a standard developer dependency. It runs on Windows, Mac, and Linux, and the basic use is simple: download the executable, run it, wait a few minutes for the scan to complete, and get a list of the fastest IPs. The results are saved to a CSV file (a spreadsheet format) that you can open in any spreadsheet app. Built in Go, a programming language known for efficiency.
