This wiki explain:

How to implement client-side (local) screen-sharing without involving any 3rd-party service or extension or addon.

First step

Chrome users: Make a ZIP of this:

Add localhost or here:

"matches": ["https://localhost:8080/*"]

Firefox users: Make XPI of this:

Add localhost or here:

var arrayOfMyOwnDomains = ['', '', 'localhost'];

Second step

  1. Chrome users: install above ZIP
  2. Firefox users: install above XPI

Third step

Download RTCMultiConnection codes:

Or via wget:

mkdir RTCMultiConnection-v3
cd RTCMultiConnection-v3
tar -zxvf rtcmulticonnection-v3.tar.gz
ls -a

Please check other options (e.g. NPM/Git/bower/etc.) here:

Fourth step

Run the server.js file and open https://localhost:9001 or

node server.js

# if you installed via NPM
cd node_moduels/rtcmulticonnection
node server.js

Last step

Try this demo:

First user should open the room, and rest should join.


  1. RTCMultiConnection is running top over which means that everything is in your own hands
  2. RTCMultiConnection is using 2-3 STUN/TURN servers however you can always remove/skip 3rd party URLs
  3. Screen sharing requires HTTPs in Firefox; however Chrome requires HTTPs for everything.
  4. RTCMultiConnection, by default, tries to use fake-certificate however you can use valid certificates as well
  5. Firefox addon or chrome extension is required to enable screen for your domain or localhost

Addon or chrome-extension is required only for the person who shares his screen. Other users don't need to install anything.
