| If you are… | Get | Why |

| Need security and support | Enterprise | Starts at $120/month and lists audit logs, SAML with group synchronization and 24/7 priority support with a 3-hour response. |

04Is Windmill worth the money?
Windmill’s free plan gives teams a way to evaluate or self-host a code-first platform without paying for executions, but it has user, workspace and storage limits. Enterprise starts at $120/month and lists security and support features, while Pro, Nonprofit and Teams prices are not published here. Seat and worker add-ons can change the bill, so count builders, other users, guests and workers before comparing plans. The price is hard to judge without a published Teams rate and full usage estimate.
