 **GoNavi** 是一款基于 **Wails (Go)** 和 **React** 构建的现代化、高性能、跨平台数据库管理客户端。它旨在提供如原生应用般流畅的用户体验，同时保持极低的资源占用。
 
 相比于 Electron 应用，GoNavi 的体积更小（~10MB），启动速度更快，内存占用更低。

+### Linux 启动报错缺少 `libwebkit2gtk` / `libjavascriptcoregtk`
+
+GoNavi 的 Linux 二进制依赖系统 WebKitGTK 运行库。不同发行版默认版本不同：
+
+- Debian 13 / Ubuntu 24.04 及更新版本：通常为 WebKitGTK 4.1
+- Ubuntu 22.04 / Debian 12 等：通常为 WebKitGTK 4.0
+
+如果启动时报错（如 `libwebkit2gtk-4.0.so.37: cannot open shared object file`），请按系统安装对应依赖后重试：
+
+```bash
+# Debian 13 / Ubuntu 24.04+
+sudo apt-get update
+sudo apt-get install -y libgtk-3-0 libwebkit2gtk-4.1-0 libjavascriptcoregtk-4.1-0
+
+# Ubuntu 22.04 / Debian 12
+sudo apt-get update
+sudo apt-get install -y libgtk-3-0 libwebkit2gtk-4.0-37 libjavascriptcoregtk-4.0-18
+```
+
+如果你使用的是 Release 中带 `-WebKit41` 后缀的 Linux 产物，请优先在 Debian 13 / Ubuntu 24.04+ 上使用；普通 Linux 产物更适合 WebKitGTK 4.0 运行环境。
