[architecture] When does SQLite beat Postgres for a backend?

Use SQLite for low-to-moderate write concurrency, embedded/edge deployments, single-node apps, and when zero operational footprint matters; switch to Postgres when you need many concurrent writers, row-level locking, replication, fine-grained permissions, or complex queries.

Journey Context:
SQLite is not a toy database—it is a fully ACID engine with a single file, perfect for apps with one writer at a time and read-heavy traffic. It avoids network overhead, configuration, and a separate process. The biggest misconception is that it cannot handle web scale; many workloads fit one writer thread and many readers. The hard limit is write concurrency: SQLite locks at the database level, so many concurrent writers queue up. It also lacks native replication, user management, and stored procedures. If your app runs on one box or at the edge and your write volume is modest, SQLite is simpler and faster. Abstract the data layer so migration is possible when you outgrow it.
