Microsoft Dev Tunnels

Dev tunnels let developers expose a locally running web service to the public Internet without opening firewall ports or configuring external proxies. The tool creates a secure tunnel that forwards traffic from a public endpoint to the developer’s machine, and it enforces access control so only authorized users can reach the service. This enables testing, debugging, and demonstration of web applications from any location.

The command‑line interface provides quick creation and management of tunnels, supporting configuration of group policies for enterprise environments. Documentation includes step‑by‑step guides, reference material, and video demos to help users get started and explore advanced features such as custom access rules.

Targeted at developers who need to share local services for remote collaboration, troubleshooting, or client reviews, the software runs on macOS and is marked as stable, indicating it is ready for production use.
