TestMu AI Tunnel is a secure and encrypted tunneling feature that allows developers and QA professionals to test their locally hosted web applications or websites on TestMu AI's cloud-based real machines. It establishes a secure connection between the user’s local machine and the real machine in the cloud, enabling testing of internal applications on various browsers and devices.
