    Where it stands

    Rank, growth pace and release cadence relative to everything GStars tracks.

    No releases in the last 90 days; the most recent was 186 days ago, with 16 contributors on GitHub.

    Peaked at #25 in the weekly ranking the week of Dec 21, its best in the past year.

    Use Cases & Benefits

    • Tests latency and download speed of Cloudflare CDN and other CDN IPs to identify the fastest IP addresses (IPv4 and IPv6).
    • Enables precise selection of optimal IPs by combining latency and download speed tests with customizable filtering parameters.
    • Use for optimizing Cloudflare CDN IP selection to reduce latency and improve speed for users in mainland China.
    • Use for benchmarking and comparing multiple CDN providers or websites with multiple resolved IPs to find the best performing endpoints.
    • Use for network administrators or developers needing automated, configurable IP speed testing on Windows, Linux, or embedded devices.

    From the README

    国外很多网站都在使用 Cloudflare CDN,但分配给中国内地访客的 IP 并不友好(延迟高、丢包多、速度慢)。 虽然 Cloudflare 公开了所有 IP 段 ,但想要在这么多 IP 中找到适合自己的,怕是要累死,于是就有了这个软件。

    「自选优选 IP」测试 Cloudflare CDN 延迟和速度,获取最快 IP (IPv4+IPv6)!好用的话点个⭐鼓励一下叭~
