CrossLoop – Simple Secure Screen Sharing

What is Crossloop?

CrossLoop is a FREE secure screen sharing utility designed for people of all technical skill levels. CrossLoop extends the boundaries of VNC’s traditional screen sharing by enabling non-technical users to get connected from anywhere on the Internet in seconds without changing any firewall or router settings. It only takes a few minutes to setup and no signup is required.

CrossLoop’s underlying technology was created to simplify the process of securely working with others located in different physical locations across diverse network environments. CrossLoop enables you to see the screen and control the mouse and keyboard on a remote computer. It is as if you are working side by side at the same PC. CrossLoop is a powerful productivity tool that enables you to quickly collaborate in with anyone in the world.

CrossLoop is powered by the proprietary CrossLoop VIP Tunnel, a secure peer-to-peer data transmission system. CrossLoop encrypts all files and messages exchanged on our network to ensure user privacy. Only you and your invited friends or family can view or share control of your computer. A CrossLoop session can only begin on your computer by explicitly inviting them to begin a session. All data sent over the CrossLoop network is encrypted at the endpoints using a 128-bit Blowfish encryption. For more detailed information on CrossLoop security, visit our security page.

We have gone to great lengths to ensure that CrossLoop is secure and have designed the application from the ground up with security in mind. If you have any questions regarding CrossLoop security please contact us at

The Windows version of CrossLoop uses the TightVNC software plug-in for screen sharing. We have included a binary distribution of the TightVNC program in the installation software of the Windows version of CrossLoop to save you the trouble of separately downloading and installing TightVNC. If you have any questions about your rights related to TightVNC (which is licensed under GPL), please see our detailed description of how we use VNC.

Starting a Session

After installing CrossLoop, you will see a welcome screen with two tabs. Select the Join tab if you would like to connect and control a friend’s PC. Select the Host tab if you would like to temporarily share access to your PC.

If you have not already done so, download CrossLoop.
