SQLitevsPostgreSQL

SQLite vs PostgreSQL ComparisonA file-based embedded database vs the production SQL standard

SQLite is a file-based, serverless database: no setup, no daemon, no configuration. PostgreSQL is a full client-server relational database built for multi-user, high-concurrency production workloads. For traditional web applications, PostgreSQL is the default. SQLite's renaissance comes from edge deployments: Cloudflare D1, Turso, and LiteFS make SQLite viable for distributed, low-latency, local-first applications that don't need central server writes.

Detailed comparison

Setup & operations
SQLite
Zero setup: it's a file. Open it and query. Perfect for development.
PostgreSQL
Requires a running server process, user management, connection pooling, and ongoing maintenance
Concurrent writes
SQLite
Single-writer model: concurrent writes are serialized, a bottleneck under load
PostgreSQL
Full MVCC concurrency: thousands of simultaneous readers and writers with row-level locking
Edge & serverless deployment
SQLite
Native fit for edge: Cloudflare D1, Turso, LiteFS, and local-first apps are all SQLite-based
PostgreSQL
Can run at edge via Supabase or Neon, but the architecture adds latency that SQLite avoids
Advanced SQL features
SQLite
Full SQL support including CTEs and window functions, but limited types and no stored procedures
PostgreSQL
Best-in-class SQL: JSON, arrays, full-text search, custom types, extensions, stored procedures
Production reliability
SQLite
Extremely reliable for read-heavy, embedded, or single-writer workloads
PostgreSQL
Battle-tested for high-traffic production workloads: financial systems, SaaS, large-scale web apps
Local development
SQLite
Ideal: no Docker, no process management. Clone the repo, the database is already there.
PostgreSQL
Requires Docker or a local Postgres install, which adds friction to onboarding new developers
Hosting costs
SQLite
Free: it's a file. Turso has a generous free tier. Cloudflare D1 is nearly free at moderate scale.
PostgreSQL
Managed Postgres (Supabase, Neon, RDS) costs $20–100+/month at production scale

Our verdict

We recommend: PostgreSQL

PostgreSQL is the right default for traditional web applications: multi-user, concurrent writes, production hardening that SQLite can't match. SQLite wins for edge deployments, embedded tools, local-first applications, and development environments where you want zero infrastructure.

When to choose each

Choose SQLite when:

  • You're building a local-first application where data lives on the user's device and syncs occasionally
  • You're deploying to the edge via Cloudflare Workers, D1, or Turso for low-latency globally distributed reads
  • You're building a CLI tool, desktop application, or embedded system that needs a local database
  • You want zero-infrastructure development environments: no Docker, no Postgres setup for new contributors

Choose PostgreSQL when:

  • You're building a traditional multi-user web application with concurrent reads and writes
  • You need advanced SQL features: JSONB columns, full-text search, custom types, or PostGIS
  • You're deploying to a central server or cloud and need production-grade RDBMS reliability
  • Your application uses Supabase, Neon, or another managed Postgres platform
