Bundled features: Edge-first Workers integration

What it is

D1 is Cloudflare's SQLite-based serverless database. Tight Workers integration, free tier with 5GB storage and 25M row reads/day, low pricing past the free tier. Read replicas across Cloudflare's network for low-latency reads.

Best for

  • Cloudflare Workers apps wanting database in the same runtime
  • Cost-sensitive deployments — D1 is among the cheapest at scale
  • Edge-first architectures where data lives close to compute

When not to pick it

Skip D1 if you are not on Cloudflare Workers — the integration is the value. Skip for write-heavy workloads; Cloudflare's SQLite is read-optimised.

My take

D1 is the right fit for Cloudflare-stack apps. Outside that ecosystem, Turso is more flexible and Supabase / Neon are stronger for full-stack briefs.
