Microsoft Dev Tunnels for Mac

Overview: Secure remote access for local apps

Microsoft Dev Tunnels is a free utility that lets developers expose web services running on their local machines to the internet. It removes the need for complex network setup, making it easier to share development servers for collaboration and testing.

How it works

The tool establishes encrypted tunnels from a local service to a reachable endpoint, so teammates or external testers can access your app without changing router settings or modifying firewall rules. Connections are routed securely, providing a direct link to the running instance on your workstation.

Who benefits

Distributed development teams, contractors, QA engineers, and anyone needing to demo a work-in-progress will find this especially useful. It speeds up feedback loops by letting others connect to a live development environment without lengthy configuration steps.
