[architecture] When is SQLite actually the right choice over Postgres?

Choose SQLite when the data lives on a single node, concurrency stays low \(roughly tens of writers or fewer\), and you value zero operational overhead over distributed scalability; switch to Postgres when you need many concurrent writers, separate application/web servers, or complex access control.

Journey Context:
Developers reflexively reach for Postgres because it is 'serious,' but SQLite is often faster for read-heavy, single-box workloads and removes an entire failure mode \(network, connection pools, replication lag\). The SQLite site itself says it excels in embedded systems, small websites, and local caches. Where teams go wrong is using SQLite behind multiple application servers with high write concurrency or treating it as a drop-in replacement for a network database. The right mental model is: one application process, one file, zero admin. If that matches your deployment, SQLite is not just acceptable—it is simpler and more reliable.
