Supabase vs Prisma Postgres

SEPT 2026 audit

A comparison of Supabase and Prisma Postgres built from values read directly from each provider's own documentation, with the source recorded against every figure.

Reviewed by Palash BagchiUpdated 28 criteria comparedSources last checked

The short answer

Choose Supabase if…

Teams who want Postgres plus auth, storage and generated APIs from one vendor on a fixed monthly bill, and who would otherwise assemble those pieces themselves.

Editorial · Palash Bagchi · approved

Choose Prisma Postgres if…

Prisma ORM users who want the database and the client from one vendor, with a pooled connection limit stated per plan rather than left to be discovered.

Editorial · Palash Bagchi · approved

Consider something else if…

  • Supabase: You want only a database. Much of the $25 covers a platform you may not use, and free projects are paused after a week of inactivity, which is not the same as scaling to zero.
  • Prisma Postgres: Four separate meters — requests, memory, vCPU and bandwidth — sit on top of the plan fee, so the monthly number is a floor rather than a bill.

Documented by only one.

These criteria are published by one provider and not the other. An absence here means we have not found a source, not that the feature is missing — except where we say we read the other provider's own page on a given date and it does not state it. Those rows lean, and the provider can correct them with a link.

Credit card to startPrisma Postgres: No
When the free offer endsPrisma Postgres: Never — the free tier has no time limit.
Egress over allowanceSupabase: $0.09 per GB for uncached egress and $0.03 per GB for cached, charged only above the plan's quota. Egress restrictions clear at the next billing cycle, or immediately on upgrading or disabling the spend cap.
Startup credit programPrisma Postgres: Prisma for Startups: database bill covered up to $10,000 for one year, plus 1:1 guidance. Venture-funded track requires pre-seed/seed/Series-A funding raised in the last 12 months and founded in the last 5 years; bootstrapped track requires ≥5k MRR for 6 months and 2 full-time team members.
Included bandwidthSupabase: 250 GB uncached and 250 GB cached egress a month on Pro and Team, pooled across Database, Auth, Storage and every other service as one Unified Egress Quota
RegionsSupabase: 17 specific AWS regions across the Americas, Europe, Asia-Pacific and South America, plus broader 'general region' groupings that place the project on an available AWS region within an area. General regions do not support read replicas or API management.
Uptime SLASupabase: Uptime SLAs are an Enterprise line item. No uptime percentage appears anywhere on the pricing page; Team lists "priority email support & SLAs" without a figure.
Database branchingSupabase: Supported
Point-in-time recoverySupabase: Point-in-time recovery is a paid add-on on Pro, Team and Enterprise, and needs at least a Small compute add-on alongside it. Worst-case recovery point is 2 minutes. Without it, restores go back only to a daily backup.
