How this stays local: Watchpost's Python code runs in WebAssembly via Pyodide, served from this site. There is no upload endpoint, and the page's content security policy blocks sending data to any other site.

Observations, not a security verdict. Only compare scans of networks you are authorized to test. Prefer a terminal? pip install watchpost-cli · Source · Wiki
