Code hosting, package registries and developer communities. An address with a decade of commits reads very differently from one with no history anywhere - a strong signal for signup fraud scoring.
Developer platforms - code hosting, package registries, coding challenges and Q&A sites - carry some of the most reliable history on the internet, because real engineers keep the same account for a decade. A developer account lookup tells a SaaS or cloud business whether a new signup has any of that history. Free trials, credits and compute are expensive to give to bots and resold accounts, so a signup with no developer footprint anywhere is worth a second look before the credits flow. Digital Footprint checks every developer platform below from an email address or username in the same request as 800+ other platforms, and returns only what it can confirm.
