VPN分流助手

About

厌烦了每次在国内外网站之间切换时都要手动开关 VPN 吗？KM VPN Auto-Switcher 是一款专为进阶用户设计的工具，旨在根据您访问的 URL 自动优化您的网络环境。

大多数 VPN 客户端缺乏针对特定区域应用的细粒度分流（Split-tunneling）或“智能模式”。本扩展通过拦截导航请求，并直接与 macOS 系统上的 Keyboard Maestro 通信，在页面加载前预先切换 VPN 状态，从而完美解决这一痛点。

核心功能：
智能拦截：根据您的自定义规则，自动检测目标 URL 需要 VPN 连接还是本地直连。

KM 触发集成：通过调用 kmtrigger:// 协议，执行您特定的 Keyboard Maestro 宏。

一键分类：利用直观的弹出界面，瞬间将当前网站加入“需要 VPN”（蓝色）或“国内直连”（红色）名单。

安全恢复：采用专门的热键握手机制（Shift+Alt+L），确保在系统级网络切换完成后才加载页面。

工作原理：
点击链接：您发起访问请求。

识别规则：扩展程序识别该域名的路由需求。

触发宏：自动触发指定的 Keyboard Maestro 宏来切换 VPN。

释放加载：宏运行完毕后，向 Chrome 发回按键指令，释放拦截并加载网站。

⚠️ 重要要求：
本扩展并非独立 VPN。它是一款专为 macOS 用户设计的桥接工具，要求用户必须安装 Keyboard Maestro，并已配置好用于切换 VPN 的自定义宏。

Tired of manually toggling your VPN every time you switch between international and domestic websites? KM VPN Auto-Switcher is a specialized power-user tool designed to automate your network environment based on the URL you are visiting.

Most VPN clients lack granular split-tunneling or "Smart Mode" for specific regional apps. This extension solves that by intercepting your navigation requests and communicating directly with Keyboard Maestro on your macOS system to switch VPN states before the page loads.

Key Features:

Intelligent Interception: Automatically detects if a destination URL requires a VPN or a direct local connection based on your custom rules.

KM Trigger Integration: Fires custom kmtrigger:// protocols to execute your specific Keyboard Maestro macros.

One-Click Categorization: Use the intuitive popup interface to instantly add the current site to "VPN Required" (Blue) or "Domestic" (Red) lists.

Secure Resumption: Uses a dedicated hotkey handshake (Shift+Alt+L) to ensure the page only loads after your system-level network switch is complete.

How it works:

You click a link.

The extension identifies the routing requirement.

It triggers your specific Keyboard Maestro macro to toggle the VPN.

Once the macro finishes, it sends a keystroke back to Chrome to release the link and load the site.

⚠️ IMPORTANT REQUIREMENT:
This extension is NOT a standalone VPN. It is a bridge tool specifically designed for macOS users who have Keyboard Maestro installed and configured with custom VPN-toggling macros.
