Account pricing

Start small. Scale the auth surface when it is real.

Questions

Practical billing details

Is billing per project or per account?

Billing is account-scoped. Projects under the account inherit the active plan and its limits.

Can I start free?

Yes. The Free plan is meant for evaluation and early integration work, with strict usage and project limits.

Why is Enterprise custom?

Enterprise depends on negotiated usage, security review needs, launch support, and rollout requirements.

Do you claim SOC 2 or HIPAA here?

No. We do not claim completed SOC 2, HIPAA, or external audit status on this pricing page.
