| Which plan to pick | Start on Free. Move to Professional when you launch, mainly for daily backups and the bigger limits. Business is a big jump aimed at teams of 50 or more, so most readers will never need it. | Build on Free. Switch to Pro the day you share the app with anyone outside your team, mostly so the project stops pausing. Team is a big jump that only makes sense once a client or auditor asks for SSO or a SOC 2 report. |
