Which plan to pickStart 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.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.Use the trial to get your app running, then move to Hobby. Many small apps stay within its included $5. Switch to Pro when a team works on it or it needs more power, and set a usage limit either way.
