Common questions

No hidden plan details.

Can a closed-source project use Authlib?

Yes. The BSD-3-Clause license permits use in open- and closed-source projects when its conditions are followed.

Do paid plans unlock protocol features?

No. Paid plans are for commercial licensing, sustainability, and support rather than a separate feature edition.

What counts as priority consultation?

Protocol guidance, implementation review, migration planning, and Authlib-related production questions can be handled through the Pro plan allowance.
