What's Good
MIT. Server and browser helpers for registration/authentication ceremonies. You own sessions and users. No hosted IdP tax for the library itself.
The Catch
Passkeys ceremony lib — not Hanko/Better Auth/Auth.js IdP or auth framework. You still store credentials and issue sessions. Distinct from Hanko, Better Auth, and Auth.js.
Verdict
MIT WebAuthn helpers. Library only; bring your own IdP.
