Cloudflare D1

SQLite at the edge.

What It Is

D1 is a serverless SQL database built on SQLite. It runs at the edge, close to Workers, with automatic replication and scaling.

How We Use It

D1 handles structured data queries:

• Index storage: Query indexes for Nomos event streams
• Metadata: User accounts, billing, and configuration
• Search: Fast lookups by various dimensions
• Analytics: Aggregated usage data

Why It Matters

SQLite’s simplicity combined with edge distribution means fast queries without managing database infrastructure. The familiar SQL interface makes development straightforward.
