What is Neutralinojs?#

Neutralinojs is a lightweight and portable application development framework. It lets you develop cross-platform applications using JavaScript, HTML and CSS. Neutralinojs applications will work on Linux, Windows, macOS, and Web.

Why Neutralinojs?#

In Electron and NWjs, you have to install Node.js 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.
