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.Build and test on Hobby. The day the site is for a business, move to Pro, since Hobby doesn't allow commercial use. One developer seat is enough for most small businesses because people who only review can join free as viewers. Turn on a spending limit straight away.
