Cloudflare D1

Cloudflare D1 is a serverless relational database built on SQLite that replicates data globally to minimize latency for distributed applications.

D1 brings SQL to the edge by leveraging SQLite (the world's most deployed database engine) and integrating it directly into the Workers ecosystem. It eliminates the need for complex connection pooling or manual regional provisioning: you define your schema, and Cloudflare handles the storage and replication. With features like Time Travel for point-in-time recovery and a generous free tier (5 million rows read per day), it is the go-to choice for developers building high-performance, data-driven apps without the overhead of traditional RDS management.
