Which plan to pickBuild 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.Don't start here for a weekend project; Neon or Supabase are free. When a product has paying customers, the $15 high-availability Postgres is the sensible entry point. Only go to Metal once Insights shows the disk is the slow part.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.
