Build with Humanity

Choose between SDK/API integration (traditional web2) or on-chain smart contracts (web3) to add proof-of-humanity verification. Includes quickstart links for both paths.

🔐 Looking for SSO? Our SDK quickstart provides "Sign in with Humanity" — same OAuth pattern as Google or GitHub login, working integration in ~10 minutes. ▶️ SDK QuickStart

Humanity is an identity and verification layer you can add to web apps, mobile apps, and smart contracts.

SDK / API

For web, backend, and mobile applications

Human verification and much more via OAuth. React SDK, Connect SDK, and REST API.

ON-CHAIN

For decentralized applications

Work directly in smart contracts using the Verification Oracle.
