Documentation Blog Guide Cloudflare D1 is a natively serverless SQL database built on the SQLite engine. It allows developers to create and manage relational databases that integrate directly with Cloudflare Workers, providing a complete stack for building full-stack applications on a global network. Cloudflare D1 offers a low-cost, usage-based pricing model that only bills for storage and the specific queries you run, with no charges for idle time or data egress. Developers can also get started for free with the Workers Free plan, which includes daily limits of five million rows read, 100,000 rows written, and up to 5 GB of total storage. D1 is built to support production-scale needs, allowing for individual databases up to 10 GB in size. Additionally, users can manage up to 50,000 separate databases within a single account, facilitating highly modular or per-tenant architectures. You can manage D1 through both the Cloudflare dashboard and the Wrangler command-line interface. These tools provide parity for essential tasks such as bootstrapping data, creating tables, and triggering backups, making the database accessible regardless of your preferred workflow. Developers can use Hyperdrive in combination with Workers to connect their applications to legacy cloud databases. This allows for a hybrid approach where you can maintain globally distributed applications while still querying existing data stores. Time Travel is a built-in restoration tool that provides always-on backup capabilities. This feature allows you to roll your database back to any specific minute within the last 30 days, ensuring you can quickly recover from mistakes or unexpected issues.
