Is Supabase cheaper than Amazon RDS?
Short answer: it depends on your workload. Supabase bills around the clock; Amazon RDS bills around the clock. The two cases below flip the answer.
Supabase: Postgres plus a backend (auth, storage, realtime), always on. It bills $25/mo Pro floor, then compute add-ons and usage.
Amazon RDS: Managed Postgres on AWS, billed around the clock per instance. It bills per instance-hour, 24/7, no scale-to-zero.
So Supabase is cheaper than Amazon RDS for steady, always-on databases, and more expensive for the other. Your real answer depends on your compute size, how many hours a day the database is active, and your storage.
