How It Works?

You don’t need to perform login or registration in order to make calls! Just enter your name and room name and click Start the button. Use the copy link feature to send out the link to your friends. As soon as they join the room, the call connects. As easy as that.

This is a one to one solution. Which means only two users can join at a time in the same room. But there is no restriction in room creation and number of calls.

Try the native app-like experience with CallCafe, thanks to PWA.

Progressive Web Apps(PWA) use modern web capabilities to deliver an app-like user experience. They evolve from pages in browser tabs to immersive, top-level apps, maintaining the web’s low friction at every moment.
