Supabase Database vs Cloudflare D1
An honest, mathematical pricing and capability comparison for developers and engineering leaders.
What this comparison covers
One database without replication or embedded sync. D1 and Turso use SQLite-compatible engines; Supabase uses PostgreSQL. These are cost alternatives, not interchangeable runtimes. Supabase models one Micro instance; its performance is not inferred from row counts.

Cost breakdown and exclusions
- Monthly subscription: $25.00
- Database disk (8 included): $0
- Uncached data transfer (250 included): $0
- Includes first Micro instance through the $10 compute credit. Fixed compute capacity; row volume alone cannot prove this instance is sufficient. Pro subscription can be shared with Supabase Auth.
- Larger compute, replicas, point-in-time recovery, provisioned IOPS and other backend features.
Cloudflare D1
Managed SQLite with row-based metering.
$5.00 / month
Workers Paid + D1
