| 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. | Free covers more than you'd expect, including several small live apps. Move to Launch when a project needs more than 100 compute hours a month or a longer restore window. Scale is for teams that need an SLA, not for individuals. | 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. |
