This is very cool. My only comment, i would consider changing or adding to your description, "Present any website without additional software!" something like, "remote website presentations - nothing to install". It took me a bit to grasp why this tool would be useful. It's for doing remote website-only presentations.

I can see this working well with online presentation services such as http://www.rvl.io/, https://presentate.com/, https://speakerdeck.com/, https://www.lucidchart.com/, http://www.slid.us/ etc. Or build-your-own tools like http://jmpressjs.github.io/customize/, http://flowtime-js.marcolago.com/, http://imakewebthings.com/deck.js/, etc.

There is no need for VNC or Teamviewer any more if you just want to show someone a website. Copy the bookmark, go to your site, click onto the bookmark. A window opens and the site you are looking at will be rendered. There is a link which you can provide to your customer to see what you see.

Awesome tool - love it! Reminds me of https://lilnub.com
