Zapsnap

Zapsnap is a free and open source product for temporary screenshot sharing from your Mac. The images are being shared with other people as long as you keep your browser open. Once you close it, the sharing depends on other available peers, so the sharing stops once all the browsers are closed.

We support modern browsers with WebRTC support: Chrome, Opera and Firefox. We plan to keep Zapsnap free for everyone and we will soon be releasing Windows and Linux apps.
