FR-AI / ANALYSISWhy it is worth attention
It combines BBRv3 installation with per-region qdisc tuning (FQ_CODEL, CAKE, FQ) and Cloudflare edge-route analysis to auto-recommend the best settings, plus a stealth WAF bypass mechanism for certain cloud regions.
Who it is for
- VPS owners on Debian/Ubuntu wanting to optimize network performance
- System administrators managing web servers or proxy nodes in Asia-Pacific or transcontinental links
- Self-hosters looking for a turnkey BBRv3 solution with minimal config effort
- Networking enthusiasts experimenting with advanced tc qdisc profiles
Use cases
- Boost website and proxy speed on Asia-Pacific VPS (JP/SG/HK/KR) with low-latency tuning
- Maximize single-thread throughput on long-distance Europe/US links for VPN or proxy
- Quickly verify BBRv3 activation and qdisc status after kernel upgrade
- Safe upgrade to XanMod kernel while preserving fallback boot option via GRUB
Strengths
- Supports multiple Debian/Ubuntu LTS releases and automatically selects stable or mainline XanMod kernels
- Geolocation-aware menu highlights recommended qdisc scheme based on Cloudflare routing analysis
- Built-in stealth retry and UA spoofing to bypass Cloudflare 403 blocks on sensitive IPs
- One-click health check (option 5) cross-validates kernel version, sysctl params, and active tc qdisc
Considerations
- Only works on Debian 12/13 and Ubuntu 20.04+ LTS (not other distros or non-LTS Ubuntu)
- The Cloudflare-based region detection may fail if the VPS is not behind Cloudflare or uses a different CDN
- WAF bypass techniques (e.g., UA spoofing) could be considered aggressive and may violate some host ToS
README quick start
⚡ Debian / Ubuntu 一键安装 XanMod BBRv3 & 智能网络调优
一款专为 Debian 12/13 以及 Ubuntu 20.04/22.04/24.04/26.04 (LTS) 深度定制的 BBRv3 一键安装、升级与多场景网络队列调度（qdisc）双系统调优工具。
🌟 项目亮点
- 双系统完美适配：支持 Debian 12/13 和 Ubuntu LTS 常见版本（Debian 12 自动适配稳定 LTS 内核，Debian 13 及 Ubuntu 自动适配最新 Main 主线内核），稳定、高效、无后门。
- 高精度战区判定：集成 Cloudflare 边缘路由链路分析，100% 精准识别 VPS 出网物理归属，菜单自动高亮推荐最佳方案。
- 4 重静默冗余绕过 WAF：内置 UA 伪装、IPv4 降级与临时文件落地校验，并采用静默重定向技术。不仅能彻底解决阿里云香港、AWS JP等高危 IP 遭遇的 Cloudflare 403 证书阻断，还能保证终端界面无任何报错杂音，极致干净。
- 智能版本比对与热应用：若已是最新内核，自动跳过内核安装并立即热应用
sysctl网络参数，修改配置免重启，即改即用。 - 闭环一键体检 (5号选项)：实时核对
uname、sysctl及tc qdisc网卡调度层，完美闭环验证加速效果，并高亮输出内核与 BBRv3 运行状态。
🚀 极速一键运行
使用 root 用户登录您的 Debian 或 Ubuntu 服务器，复制并运行以下命令：
bash "Talk is cheap. Show me the code." —— 保持热爱，奔赴山海。
