[architecture] When should I use SQLite instead of Postgres for my application?

Use SQLite for single-server, low-write, embedded, or mobile apps where simplicity and zero-configuration matter. Use Postgres for multi-server, high-concurrency, complex queries, or when data integrity under concurrent writes is critical.

Journey Context:
Common mistake: using SQLite for web apps with many concurrent writes because it serializes writes \(single writer\). SQLite excels for read-heavy, single-process, or local storage \(e.g., desktop apps, mobile, IoT\). Postgres offers full ACID with MVCC, rich indexing, and horizontal scaling. Alternatives like DuckDB for analytics exist, but SQLite's simplicity and reliability win for embedded use. The official SQLite documentation clearly states its intended use cases.
