[DEPRECATED] Build browsers and browser like applications with HTML, CSS, and JavaScript

Project README

Muon is a framework that leverages the full power of Chromium including extensions support, and allows you to build browsers and browser like applications with HTML, CSS, and JavaScript. Node is added into the browser process only for security reasons.

It may be a better fit than Electron for your application, if your application needs to leverage the full support of Chromium, needs tighter security, or needs support for things like autofill and extensions. See the Moving from Electron to Muon guide to help make the transition.

Some of Muons goals include:

  • use the Chromium source directly (eliminating electron's copy of chrome_src) with minor patches
    • make integrating chrome components less painful
    • faster and more streamlined end-to-end build process (see browser-laptop-bootstrap)
  • add support for Chrome extensions
  • add security focused features for the renderer:
    • remove node completely (from the renderer process)
    • full sandbox
    • scriptable window.opener support

Muon is a fork of the Electron framework which is currently used in the Brave web browser.
