Cloudflare D1

Overview

D1 is Cloudflare's serverless SQLite database — runs at the edge alongside Workers. Zero connection overhead (it's in the same data center as your Worker), SQLite query syntax, automatic replication, and pay-per-query pricing. Perfect for read-heavy workloads, content sites, and applications where latency matters.

When to Use

• Building on Cloudflare Workers and need a database
• Read-heavy applications (blogs, content sites, APIs)
• Want SQLite simplicity with global distribution
• Serverless applications with no connection pooling headaches
• Edge-first applications where database latency matters
