Neutralinojs is a lightweight and portable desktop application development framework. It lets you develop lightweight cross-platform desktop applications using JavaScript, HTML and CSS. Apps built with Neutralinojs can run on Linux, macOS, Windows, Web, and Chrome. Also, you can extend Neutralinojs with any programming language (via extensions IPC) and use Neutralinojs as a part of any source file (via child processes IPC).

Why Neutralinojs?

In Electron and NWjs, you have to install NodeJs and hundreds of dependency libraries. Embedded Chromium and Node make simple apps bloaty. Neutralinojs offers a lightweight and portable SDK which is an alternative for Electron and NW.js. Neutralinojs doesn't bundle Chromium and uses the existing web browser library in the operating system (Eg: gtk-webkit2 on Linux). Neutralinojs implements a WebSocket connection for native operations and embeds a static web server to serve the web content. Also, it offers a built-in JavaScript client library for developers.

Windows 无地址栏弹窗

Windows WebView2 支持通过 window.open("", "neutralino-popup:editor", "width=1000,height=700") 创建无地址栏的空白弹窗。仅名称以 neutralino-popup: 开头且地址为 about:blank 的请求使用该行为；其他请求仍交由 WebView2 默认处理。

弹窗使用系统标题栏，与主窗口处于同一进程，保留浏览器 Window 引用、同源文档访问、页面标题及 window.close() 行为。弹窗不额外初始化 Neutralino 原生 API，也不创建业务后端通信。通过根目录 编译.bat 构建 Windows 运行时。
