Open source: yes (MIT); self-hostable; pricing free. The honest read: the offline-first, dual-search design is a genuinely useful discovery primitive, but the ~3.48M-asset / 113k-server index counts are the maker's own figures, the local snapshot can drift out of date, and this is a 0-star launch-day project — treat it as a fast local index to refresh, not an authoritative live registry."
