AI-assisted scores estimated from public website information only.
This FounderDeck estimate of $75,000 reflects a highly functional, polished, and privacy-focused tool that solves a real security problem. The v2.0.0 and comprehensive checks demonstrate strong execution and utility. However, the explicit 'free, open-source' and 'no data stored, no account' model means there is no visible direct monetization path, limiting its current valuation as a commercial startup. It holds significant value as a community resource or a strong personal project.
