Databases: cheapest modeled plans
Eligible plans ordered by monthly equivalent at the workload below. A low subscription fee alone does not establish the cheapest total.
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.
Evaluating 4 products from 4 published in this category. USD monthly equivalents, before tax. Features and service compatibility need separate evaluation.
