About
Cloudflare D1 is a managed, serverless SQL database built on SQLite semantics for applications running on Cloudflare Workers and Pages. It is designed for horizontal scale across many smaller databases, making it well suited for per-user, per-tenant, or per-entity data isolation.
The service provides Worker and HTTP API access, built-in disaster recovery, and support for querying data directly from Cloudflare’s developer platform. It also includes Time Travel for point-in-time recovery and integrates with Cloudflare’s broader application stack.
