FAQ
Does Supabase's free plan pause my project?
Yes. Free projects are paused after one week of inactivity. Upgrade to Pro (from $25/month) for always-on projects.
Supabase or Firebase?
Choose Supabase for relational data and SQL; choose Firebase for mobile-first apps that benefit from its document model and Google integrations. See our Supabase vs Firebase comparison.
What if I only need a database?
Neon is serverless Postgres billed purely by usage with no monthly minimum. Pair it with an auth provider like Clerk.
