How does Cloudflare D1 SQL pricing compare to other serverless SQL databases like AWS Aurora Serverless or Supabase?

Cloudflare D1 generally aims for a simpler, more aggressive pricing model, particularly attractive for edge-native applications. Compared to AWS Aurora Serverless, D1 typically has a lower cost floor and a more predictable, usage-based fee for operations and storage, whereas Aurora Serverless involves more complex pricing for compute capacity units (ACUs) and I/O. Supabase pricing, while also usage-based, often bundles PostgreSQL hosting with other services like Auth and Storage, making direct comparisons tricky but generally putting D1 in a very competitive position for pure SQL database needs at the edge due to its simplicity and often lower per-operation cost.
