I’ve been using it daily for about 2 weeks now and have found it’s very easy to use and a very useful tool. In my current work, I am full time pairing with a teammate, and CoScreen is the best pairing tool we’ve used so far.

Anthony Marchante,
Sr. Platform Engineer

CoScreen is probably the easiest way to do pair programming and dev collaboration that there is.

Multi User
Remote Control
  • Alice and Bob can interact with Alice's window.
  • Alice and Bob can interact with Bob's window.
Cross-User Copy & Pasting

Mob Collaboration
With More Than 2 Users
  • Chris, Dennis and Eve join Alice and Bob's to collaborate, share and contribute just like they do.

Seamlessly collaborate on whatever app you prefer

Collaborate with your team on any IDE, dev tool, desktop and web application.

Remote debugging is not only about sharing your IDE

Collaborative IDEs are helpful tools for pair programmers. But you often need to collaborate on much more than code, e.g. on emulators, command line tools and issue management systems. CoScreen enables you to collaborate across all of them and also any other desktop applications.

This illustration was inspired by Clemens Mewald's presentation at the TensorFlow Dev Summit 2018.

Because CoScreen enables you to share and collaborate on any desktop and browser application, it enables the perfect combination for users of collaborative IDEs like Virtual Studio Code Live Share,, TeleType for Atom, and GitDuck as you can now work together on more than just code.
