Pros & cons
Cloudflare D1
- Ultra-low latency at the edge

- Replication / multi-region story still evolving
Firebase
- Dual NoSQL databases: Firestore + Realtime Database
- Mature mobile/web BaaS ecosystem
- Realtime + auth + storage out of the box
- Deep Google Cloud integrations
- NoSQL model — not SQL/Postgres
- Vendor lock-in concerns
- Query flexibility can frustrate SQL-first teams
