SQLite vs PostgreSQL

Which database for your side project? A practical comparison.

SQLite: zero setup (single file), no server process, included in Python/Node.js, perfect for prototypes and apps with <1000 concurrent users. PostgreSQL: client-server architecture, handles millions of rows, concurrent writes, full-text search, JSON queries. For side projects: start with SQLite. When you need concurrent writes, real-time subscriptions, or row-level security, migrate to PostgreSQL (Supabase makes this easy). Migration is straightforward because both use SQL.
