Cloudflare D1

SQLite on Cloudflare Workers

Free tier + paidDatabases & backenddevelopers.cloudflare.com

What it is

A SQLite database built into the Cloudflare Workers platform and queried through a Worker binding rather than a connection string. The free plan allows 10 databases, 5 million row reads per day and 5GB total storage. Workers Paid at $5 monthly raises this to 25 billion reads.

Why it earns a slot

If your app already lives on Workers or Pages, D1 adds no extra vendor, no connection pooling and no cold start. Cloudflare ships a fleet of official remote MCP servers, including one for Workers bindings.

Know before you commit

A hard 10GB ceiling per database that cannot be raised, and free databases cap at 500MB each. D1 is only reachable from Workers, so no psql, no BI tool and no generic driver.
