-## Pricing that actually matters
+## Pricing: different meters
 
 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. |
+| **Entry paid** | Pro from $25/mo. 8 GB DB, 250 GB egress, and $10 compute credits covering one Micro instance. | Starter $10/mo. 1M operations, 10 GB, 10 DBs. |
+| **Scaling path** | Add per-project compute and usage. Team starts at $599/mo for org controls, compliance, and support features. | Pro $49/mo. 10M operations, 50 GB, 100 DBs. |
+| **Overage** | Per GB storage, per GB egress, per compute-hour, and feature add-ons. | $0.008 / 1k ops (Starter), $0.002 / 1k ops (Pro), storage from $2/GB on Starter and $1.50/GB on Pro. |
 | **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.
+1. **Supabase is easy to reason about for steady workloads.** If you know the compute size you need and want the broader backend platform around it, the model is familiar. For idle or highly bursty database-only workloads, reserved per-project compute can be less cost-efficient.
+2. **Prisma Postgres is friendlier to bursty and idle database workloads.** Operations-based pricing means an idle database does not keep accumulating compute charges. Preview branches, demos, and side projects can stay free while they are below the included limits.
 
 :::ppg
 **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're 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.
+- On **Supabase**, the free plan may be enough if pausing after inactivity is acceptable. If the project needs to stay online, Pro starts at **$25/mo** and includes compute credits for one Micro instance.
+- On **Prisma Postgres**, the same app can stay on the always-on free tier as long as it remains under the included operations and storage limits.
 
-When you do scale, $10/mo Starter covers 1M operations, more than enough for early traffic.
+When it does scale, $10/mo Starter covers 1M operations and 10 GB of storage before usage-based overages apply.

-Supabase has no first-party ORM. You get `supabase-js` and auto-generated REST/GraphQL via PostgREST, plus raw SQL. It's fine. It just stops at the client.
+Supabase does not try to be an ORM. You get `supabase-js` and auto-generated REST/GraphQL via PostgREST, plus raw SQL. That works well for SQL-first and API-first teams.

 ## 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.
