SQLite vs PostgreSQL: Why 'Just Use Postgres' Is Wrong
Most developers reach for PostgreSQL by default without asking whether the workload even needs a server. This video breaks down the real architectural difference between SQLite and PostgreSQL, why SQLite exists in the first place, and why it quietly runs more software than almost any other database on earth.
You will see the actual origin story: SQLite was written in the year 2000 by D. Richard Hipp for a US Navy guided missile destroyer, after a networked Informix server kept crashing and taking down damage control software in the middle of simulated combat. The fix was not a better server. The fix was removing the server entirely.
What is covered:
The core architectural split, serverless embedded file versus client server daemon over a network
Why SQLite is single writer with whole database locks while PostgreSQL uses MVCC for high concurrent multi writer traffic
Dynamic type affinity versus strict static typing with JSONB, arrays, and UUIDs
The exact scenarios where SQLite beats PostgreSQL, mobile and desktop apps, edge and local first deployments, data archiving, and rapid prototyping
Where SQLite is already running right now, inside Chrome, Firefox, Safari, iOS, Android, WhatsApp, Spotify, VS Code, Discord, Dropbox, automotive infotainment systems, and even Airbus flight software
The real question is never which database is better in the abstract. It is whether your workload actually needs a server at all.
