Is Cloud SQL cheaper than Supabase?
Short answer: it depends on your workload. Cloud SQL bills around the clock; Supabase bills around the clock. The two cases below flip the answer.
Cloud SQL: Managed Postgres on Google Cloud, priced per vCPU and RAM. It bills per vCPU-hour + per GB-RAM-hour, 24/7.
Supabase: Postgres plus a backend (auth, storage, realtime), always on. It bills $25/mo Pro floor, then compute add-ons and usage.
So Cloud SQL is cheaper than Supabase for bursty or idle 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.
