cfnb

这是一个全自动的 Cloudflare CDN 节点优选工具。它通过 TCP 延迟筛选 + IP 可用性二次检测 + HTTP 延迟及抖动检测 + 真实带宽测速 多重机制，从多个公开数据源中聚合节点，自动识别并解析任意格式（标准代码、中文名、emoji国旗、JSON等），筛选出当前网络环境下速度最快、延迟最低、抖动最小的 Cloudflare IP，并支持自动更新至 Cloudflare DNS 以及同步至 GitHub 仓库，同时支持微信实时通知。

What it does

自动挑选并更新最快的 Cloudflare CDN 节点到你的 DNS，让网站访问速度在当前网络环境下最优。

When to use it
  • •你的站点已经使用 Cloudflare，但在某些地区访问慢，想自动找出最优 IP 替换。
  • •需要在 CI/CD 流程里保持 DNS 记录始终指向最低延迟的节点。
  • •想把节点选择结果实时推送到微信，以便团队第一时间获知更新。
Ready-to-paste prompt
python main.py --mode auto --notify wechat --sync-github
Heads up: 首次运行前必须在 Cloudflare 为目标域名创建一个可编辑的 A 记录，并在 config.yml 中提供拥有 "Zone DNS Edit" 权限的 API Token；没有此权限脚本会因授权错误而退出。
