Paid plans start at $20/mo. There's also a free plan.
Clerk has a free Hobby plan, while paid plans start at $25 per month for Pro or $20 per month with annual billing. Hobby includes 50,000 MRUs per app, but caps dashboard access at three seats and application log retention at one day. Pro adds MFA and custom session lifetimes; Business is $300 monthly or $250 per month billed annually. The plan price is only the baseline: MRU overages, extra connections, seats, domains and usage-based add-ons can raise the bill.

03Which plan should you buy?
| If you are… | Get | Why |

| Projects starting out | Hobby | Free, with unlimited applications and 50,000 MRUs per app; account for the three-seat and one-day log-retention caps. |
| Growing products | Pro | Adds MFA and custom session lifetime, with 50,000 MRUs and one SSO and Directory Sync connection included. |
| Teams needing compliance | Business | Includes 10 dashboard seats, 30-day application and admin log retention, a SOC 2 report and advanced protections. |
04Is Clerk worth the money?
Clerk's free Hobby tier and included authentication features make it a credible starting point for apps that need sign-in, session controls and organization management. Pro and Business add specific capabilities, but the listed prices do not tell the whole cost story: MRU overages, extra connections and metered add-ons can push spend higher. We would model expected usage before choosing a paid tier. Enterprise pricing is not published, so teams needing custom terms must contact Clerk.
