Which should you use?
BuildScore verifies against the seller's accounts, which FirstPass does not. Use FirstPass to decide which micro-SaaS listing deserves a $499–$1,499 audit; use BuildScore (or similar) on the one you intend to buy.
Whatever you use, nothing that reads only the listing verifies it. Before money moves, check revenue at the source (read-only Stripe, analytics, platform dashboards).
