+
+Picking a database for your next app? Here is how [Supabase](https://supabase.com) and [Prisma Postgres](https://www.prisma.io/postgres) stack up, head to head.
+
+Quick note before we start: Supabase is also an Auth, Storage, Realtime, and Edge Functions platform. This post focuses on the **database layer**, because that is where the actual choice usually happens.
+
+## The snapshot
+
+| | Supabase | Prisma Postgres |
+|---|---|---|
+| **Cold starts** | Free projects auto-pause after inactivity | **Zero cold starts. Always-on, even on free.** |
+| **Pricing model** | Plan tier + compute add-ons + storage + egress | **Operations + storage. No compute, no egress.** |
+| **Free tier** | 2 projects, 500 MB DB, 5 GB egress, auto-pause | **5 databases, 100k operations, always-on.** |
+| **Query diagnostics** | `pg_stat_statements` views in the dashboard | **Query Insights, built in, with AI fix suggestions.** |
+| **AI / MCP** | MCP server available | **Native MCP, `npx prisma init --db`, `npm create db`.** |
+| **Core offering** | Full BaaS (DB, Auth, Storage, Realtime, Edge Functions) | Focused Postgres with ORM, Studio, Query Insights |
+| **Postgres version** | Postgres 17 on new projects (15 on older ones) | Postgres 17 |
+| **Architecture** | Dedicated Postgres instance per project | Unikernels on bare metal, thousands of DBs per host |
+| **ORM integration** | Any ORM, no first-party | First-party Prisma ORM |
+| **Direct Postgres protocol** | Yes, via pooler and direct connection | Yes, GA. `psql`, TablePlus, Hyperdrive, Kysely |
+
+## Architecture under the hood
+
+Supabase provisions a dedicated Postgres instance per project. You pick a compute size. Familiar, predictable.
+
+Prisma Postgres runs each database inside a [unikernel](https://www.prisma.io/blog/announcing-prisma-postgres-early-access) on Firecracker microVMs, on bare metal. The unikernel image is tiny (~61 MB vs. ~280 MB for stock Postgres), so thousands of databases share a host without fighting over resources. That is how Prisma Postgres delivers zero cold starts and an always-on free tier without charging for it.

+
+## Pricing that actually matters
+
+Supabase and Prisma Postgres price on different axes. Your workload shape decides which model is friendlier.
+
+| Tier | Supabase (approx.) | Prisma Postgres |
+|---|---|---|
+| **Free** | $0. 2 active projects, 500 MB DB, 5 GB egress, auto-pause. | $0. 5 DBs, 500 MB, 100k operations/mo, always-on. |
+| **Entry paid** | Pro $25/mo. 8 GB DB, 250 GB egress, small compute. | Starter $10/mo. 1M operations, 10 GB, 10 DBs. |
+| **Growth** | Team $599/mo + compute add-ons. | Pro $49/mo. 10M operations, 50 GB, 100 DBs. |
+| **Overage** | Per GB storage, per GB egress, per compute-hour. | $0.008 / 1k ops (Starter), $0.002 / 1k ops (Pro), $2/GB. |
+| **Cost control** | Spend caps available. | Spend limits on every plan, including free. |
+
+Two patterns:
+
+1. **Supabase rewards steady workloads.** A known compute size running 24/7 is easy to reason about. Bursty traffic or idle projects punish you.
+2. **Prisma Postgres rewards bursty and idle workloads.** Operations-based pricing flatlines to $0 at idle. Preview branches, demos, side projects stay free.
+
+**A concrete example.** A small startup launching an MVP with ~200 active users and a demo that idles overnight and on weekends. On Supabase, you are on Pro for $25/mo flat, even when nothing is happening. On Prisma Postgres, the same app sits inside the free tier (100k operations/mo is generous for an MVP), so your database bill is **$0** until you actually have traction. When you do scale, $10/mo Starter covers 1M operations, more than enough for early traffic.
+
+Numbers change. Check the live [Supabase pricing](https://supabase.com/pricing) and [Prisma pricing](https://www.prisma.io/pricing) before deciding.
+
+## Developer experience: ORM, schema, and queries
+
+Supabase has no first-party ORM. You get `supabase-js` and auto-generated REST/GraphQL via PostgREST, plus raw SQL. It is fine. It just stops at the client.
+
+Prisma Postgres is built around Prisma ORM. One declarative schema. Generated, type-safe client. Migrations in the same workflow. It is the whole package in one install.
+
+Here is the same query ("get a user with their five most recent posts") in both clients.
+
+```ts title="prisma-client.ts"
+const user = await prisma.user.findUnique({
+  where: { id: userId },
+  include: {
+    posts: {
+      take: 5,
+      orderBy: { createdAt: "desc" },
+    },
+  },
+});
+```
+
+```ts title="supabase-js.ts"
+const { data: user } = await supabase
+  .from("users")
+  .select("*, posts(*)")
+  .eq("id", userId)
+  .order("created_at", { foreignTable: "posts", ascending: false })
+  .limit(5, { foreignTable: "posts" })
+  .single();
+```
+
+Rename a column in `schema.prisma` and the generated types update everywhere. Your editor lights up the five places you forgot. Your CI refuses to build until they are fixed. That is the difference, and it compounds as the codebase grows.
+
+## Migrations: the quiet differentiator
+
+Supabase migrations are SQL files, run through the `supabase db` CLI, with git-tied branching and Vercel Previews. Straightforward for SQL-first teams.
+
+Prisma Migrate is schema-first. Change `schema.prisma`, run `prisma migrate dev`, and a reversible migration pops out. In CI, `prisma migrate deploy` applies pending ones. It feels obvious once you have it.
+
+The [new migration engine](/blog/rethinking-database-migrations) goes further: graph-based, with verifiable `from` / `to` schema hashes, idempotent operations, and automatic conflict resolution across branches. It is explicitly designed to stay safe when AI agents are the ones generating your migrations, which is increasingly the reality.
+
+## Query Insights and observability
+
+This is where the gap opens up.
+
+Supabase gives you a query performance view built on `pg_stat_statements`, plus a slow query log. Baseline Postgres observability. You read it yourself.
+
+Prisma Postgres ships [Query Insights](https://www.prisma.io/blog/announcing-query-insights-for-prisma-postgres) directly in the console. It tracks latency percentiles and frequency, surfaces N+1 patterns, missing indexes, over-fetching, and offset pagination bloat, and hands you an AI-generated fix with a copyable prompt for your editor. No extension, no setup, included on every plan.
+
+![Query Insights dashboard showing grouped queries and latency metrics](/supabase-vs-prisma-postgres/imgs/query-insights-dashboard.gif)
+
+If you care about making your app faster without reading `EXPLAIN ANALYZE` plans yourself, this is a real advantage.
+
+## Connection pooling and the edge
+
+Supabase uses Supavisor for transaction and session pooling, and exposes direct database connections plus PostgREST as an HTTP layer. Edge Functions run at points of presence globally.
+
+Prisma Postgres bakes pooling in, no separate config step. For edge runtimes like Cloudflare Workers, Vercel Edge, and Deno, the `@prisma/ppg` driver speaks HTTP and WebSockets, so you skip the TCP connection limits that trip up serverless.
+
+Both work at the edge. Prisma Postgres just has fewer moving parts.
+
+## Studio and data browsing
+
+Supabase's Studio is broad: Table Editor (spreadsheet UI), Monaco SQL editor with autocomplete, a visual Row Level Security policy builder, plus integrated UIs for Auth, Storage, and Logs.
+
+Prisma Studio focuses on the data itself, and ships two ways: online in the Prisma Console, and locally via `prisma studio`. Full CRUD, advanced filters, relationship-aware navigation, and multi-tab workflows. The fun part for Prisma Postgres users: Studio is **embeddable into your own app**, so you can expose a polished data editor to your team or customers without building one. See [Studio for Prisma Postgres: view and edit your data online](/blog/studio-for-prisma-postgres-view-and-edit-your-data-online).
+
+## AI and agent integration
+
+Both have jumped into AI tooling. The depth of integration is different.
+
+Supabase publishes an MCP server, supports pgvector out of the box, and has AI SDK integrations.
+
+Prisma Postgres was built around AI agents from day one. The native MCP server ships with the Prisma CLI and works with Cursor, Claude Code, Windsurf, and the OpenAI Agents SDK. Scaffold a schema and provision a database from a single prompt with `npx prisma init --db`. Spin up a throwaway DB for an AI-generated app with `npm create db` in seconds. See [Announcing Prisma's MCP Server](/blog/announcing-prisma-s-mcp-server-vibe-code-with-prisma-postgres) and [Prisma Postgres for AI Coding Agents](/blog/announcing-prisma-postgres-for-ai-coding-agents).
+
+The density model is what makes "provision a database from a prompt" economically viable. Feature and architecture working together.
+
+## When to pick which
+
+| Pick **Supabase** if | Pick **Prisma Postgres** if |
+|---|---|
+| You want bundled Auth, Storage, Realtime, and Edge Functions from one vendor. | You want the fastest Postgres setup with zero cold starts. |
+| Your team prefers SQL-first workflows and Row Level Security policies. | You want first-class, type-safe ORM integration and migrations. |
+| You need PostgREST-style auto-generated REST and GraphQL APIs. | You want operations-based pricing that flatlines to $0 when idle. |
+| You want database branching tied to Vercel Previews today. | You are building with or for AI agents via MCP and instant provisioning. |
+| | You want Query Insights with AI fix suggestions out of the box. |
+
+## Wrapping up
+
+Both are solid choices for Postgres-backed apps.
+
+Pick Supabase if you want a full BaaS in one login.
+
+Pick Prisma Postgres if you want a database that stays out of your way, with honest always-on pricing, first-class type-safe tooling, Query Insights on day one, and an AI-ready story from the start.
+
+Try it in less than a minute:
+
+```shell
+npx create-db@latest
