This repository is a stub. The current file tree contains no application source code—only a README and seven screenshots. The README explicitly states that the open-source project has been discontinued and transitioned into a commercial service at tunnl.to. There are no entry points, no executable files, no build configuration, and no code to analyze; the repo exists primarily as a notice and redirect for former users. The README explains that the old open-source version is still available for personal use but is not licensed for commercial use, and that the source was removed to avoid misleading users now that the application is closed-source. It also describes the rationale for the new UI, but none of that functionality exists in this repository. From a software engineering perspective, this is not a usable or reusable codebase; it is a deprecated project marker with screenshots and marketing/FAQ content.
