Proprietary AuthKit: first 1M MAUs Free, not OSS
Auth / Auth · Freemium
Reviewed 2026-09-04
What's Good
AuthKit first 1M MAUs Free; staging free. SSO, Directory Sync, Audit Log paths when you outgrow DIY. Polished Next.js integration. Check current Enterprise monthly prices on the vendor site.
The Catch
Proprietary — not OSS. Vs Clerk/Logto/Kinde/Hanko/Better Auth. Free MAU band is the pitch; paid enterprise features exist — check current pricing. Distinct from Clerk, Logto, Kinde, Hanko, and Better Auth.
Verdict
Proprietary AuthKit. First 1M MAUs Free; not open source.
