Cloudflare D1 is Cloudflare's managed, serverless database built on SQLite's SQL semantics, with built-in disaster recovery and access via Workers and the HTTP API.

The Cloudflare D1 Wrapper brings your D1 databases into Postgres as queryable foreign tables. Read and write D1 data with plain SQL, join it against your application data, and use subqueries in table definitions for more flexible data access. The wrapper works with Supabase Vault for secure API token management and is built on WebAssembly (Wasm) for lightweight, sandboxed execution.
