Marketplaces & gig

One stable visitor ID across web and apps. Detect anti-detect browsers, multi-account farms, and scripted onboarding.

The marketplace problem

Identity at the device — across surfaces.

Marketplaces typically run web + iOS + Android with shared accounts. Burein is the only SDK that produces a unified visitor_id schema across all three, with the same risk engine and the same threat taxonomy.

Multi-account farms

Anti-detect browsers and app cloners — both named with named threats, both correlate at the hardware-fingerprint layer.

Scripted onboarding

Bot, agent, and AI-driven signups — caught at the cadence and stack layer.

Listing & review fraud

Same device under different identities — visible the moment your risk model joins on visitor_id.
