Why a free proof-of-human toolkit?

Prove, don't guess

Bot detection scores traffic and guesses. A 5arz credential is a real signature anyone can verify — the affirmative proof layer.

Own the verification

Credentials verify against a public JWKS with any JWT library. No lock-in, no 5arz SDK required downstream.

Free to start, built to scale

Verify and test for free. Meter live verifications per credential when you're in production. See pricing →
