| Which plan to pick | Build on Hobby. It's enough until you have customers who care about the Clerk branding or need multi-factor login, then move to Pro. Business only matters when a customer asks for 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. | 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. |
