I want to start a discussion about trusted identity verification services—especially those that work well for developers building customer-facing apps. Whether it’s for user onboarding, fraud prevention, or KYC compliance, a reliable API and solid UX can make or break the experience.
These tools are among the top-rated in G2’s Identity Verification Software category:
Incode provides an SDK-first approach to identity verification, which appeals to dev teams needing clean integration with mobile or web apps. According to G2 reviews, its real-time facial recognition and liveness detection are fast and accurate, with minimal drop-off in the user journey.
Sumsub is frequently cited on G2 for its multi-layered approach to compliance, handling KYC, KYB, and AML workflows within a unified platform. Developers note its flexible APIs and prebuilt verification flows as helpful when speed-to-market matters.
iDenfy is a lightweight and affordable solution that’s popular with smaller teams and early-stage apps. G2 users highlight its drag-and-drop interface, API responsiveness, and helpful customer support as reasons it’s easy to adopt without deep dev overhead.
Persona is built for customization at scale. Its dynamic verification flows let app teams tailor experiences based on user behavior or risk levels. G2 reviewers appreciate its strong privacy posture and the granularity it offers developers managing different user types.
Onfido combines biometric verification with global document checking. According to G2 feedback, it stands out for app developers thanks to its mobile-first SDKs, high success rates on ID checks, and clear, well-maintained API documentation.
