Report #7405

[architecture] When is SQLite actually the better choice over PostgreSQL for a production web service?

Choose SQLite for read-heavy, low-write-concurrency, single-node deployments under 100GB where operational simplicity \(zero config, no network latency\) outweighs the need for concurrent write scaling or complex access control.

Journey Context:
The 'SQLite is only for testing' myth persists. For many web apps \(blogs, CMS, analytics dashboards\), SQLite's in-process nature eliminates network round-trips \(faster than Postgres for single-node\), simplifies backups \(single file\), and reduces DevOps burden. However, it fails at high-write concurrency \(WAL mode helps but has limits\), lacks fine-grained user permissions, and complicates horizontal scaling. The 'litefs' pattern \(SQLite with FUSE replication\) or Litestream for streaming backups makes it viable for production. Crucially, if you need multiple writers or row-level security, Postgres wins; if you have a single app server and can tolerate brief locks, SQLite's simplicity is a superpower.
