Which plan to pickSpark is enough until real users arrive. Move to Blaze when you need Cloud Functions or you're close to a quota, and set a budget alert the moment you do. There's no middle tier, so your bill goes straight from nothing to usage based.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.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.
