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, and Web. 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).

Get started with the neu CLI.

 # Creating a new app
 npm i -g @neutralinojs/neu
 neu create hello-world
 cd hello-world
 neu run
 # Building your app (No compilation - takes less than a second)
 neu build

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.
