Tunneling tools make services running on private networks or local machines reachable from the internet. They create a path through firewalls and network address translation, letting developers share in-progress websites, test webhooks, or expose internal services without configuring public infrastructure. Depending on the setup, a tunnel may forward HTTP traffic, TCP connections, or SSH sessions, and can provide access controls or stable addresses.

Open source options range from lightweight command-line clients and SSH-based forwarding to self-hosted reverse proxies with dashboards, authentication, and support for multiple users. When choosing a tool, consider protocol support, security controls, deployment requirements, scalability, documentation, license, and maintenance activity. These tools can help individual developers, teams, and self-hosters who need temporary or persistent access to services behind a network boundary.
