cf_speedtest

What is this?

cf_speedtest is an unofficial, cross-platform, command-line internet speed test tool, powered by https://speed.cloudflare.com. cf_speedtest leverages Cloudflare's own Speedtest API, it can achieve much higher speeds than other tools. Here is an example of cf_speedtest running on an AWS m5zn.6xlarge instance (advertised as 50Gbit capable):

Installation:

$ cargo install cf_speedtest

Usage:

$ cf_speedtest

TODO:

• Use rustls instead of ureq for download tests, to avoid TLS decryption cost
• Support for proxies (HTTP/SOCKS5)
• Option to output results to CSV file

Disclaimers:

• This tool works entirely over HTTPS, which has some overhead
• This tool is completely unofficial, Cloudflare can block this tool at any time if they wanted to (I suspect they won't, because they chill like that)
