Tuna 0.32.0, published by yuccastream, is a lightweight network utility designed to create secure HTTP, TCP, and SSH tunnels from a publicly reachable server into a local network. Built for developers, system administrators, and DevOps teams, the program removes the need for complex VPN configurations by exposing local services through encrypted reverse connections that originate inside the firewall. Typical use cases include sharing a work-in-progress web application with remote testers, providing stable webhook endpoints for continuous-integration pipelines, accessing SSH shells on home-lab machines from external locations, or letting mobile devices reach an internal REST API during prototype demonstrations. Because connections are tunneled over standard ports, Tuna avoids ISP blocks and corporate proxy restrictions while keeping the local IP address hidden. The command-line client automatically negotiates endpoints on the provider’s relay infrastructure, supports custom sub-domains, and can multiplex several simultaneous tunnels through one launched process. Configuration is file-based, allowing profiles to be version-controlled alongside source code, and optional token-based authentication prevents unauthorized forwarding. Since its first public build, the project has released twenty-six incremental versions, each refining connection stability, lowering idle latency, and tightening TLS cipher selection. The current 0.32.0 branch introduces keep-alive optimizations for long-lived SSH sessions and improves compatibility with recent OpenSSH releases. The utility is classified within the “Network Tools / Remote Access” category and is distributed as a portable Windows executable that requires no administrative rights. Tuna is available for free on get.nero.com, with downloads provided via trusted Windows package sources such as winget, always delivering the latest version, and supporting batch installation of multiple applications.
