Is Supabase cheaper than Cloud SQL?
Short answer: it depends on your workload. Supabase bills around the clock; Cloud SQL 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.
Cloud SQL: Managed Postgres on Google Cloud, priced per vCPU and RAM. It bills per vCPU-hour + per GB-RAM-hour, 24/7.
So Supabase is cheaper than Cloud SQL 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.
