I've outgrown SQLite for my web app. Is PostgreSQL the usual next step?

Yes — PostgreSQL is the most common “next step” after SQLite for a web app.

Why PostgreSQL is usually the move

• Works well under concurrent traffic: SQLite is great for a single-user app or light traffic, but it can struggle when many requests want to write at once.
• More robust for production: Better transaction handling, indexing, query planning, and reliability features.
• Scales farther: Handles larger datasets and more complex queries much better.
• Feature-rich: Support for JSON, full-text search, advanced constraints, window functions, extensions, etc.
• Easier to grow with your app: It’s a very standard choice for startups and production web apps.

When SQLite is still fine

SQLite can still be a good choice if:

• your app is small,
• writes are infrequent,
• deployment simplicity matters a lot,
• or you’re early-stage and don’t yet have concurrency pressure.

Other common options

• MySQL/MariaDB: Also common, especially if your team already knows it.
• Managed cloud databases: Like AWS RDS, Cloud SQL, Neon, Supabase, Render, Railway, etc. Often these are PostgreSQL under the hood and make operations easier.

Typical migration path

If you’re moving from SQLite, PostgreSQL is often the cleanest upgrade because:

• the SQL dialect overlap is decent,
• many frameworks support both,
• and the ecosystem is very strong.

If you want, I can also help you decide whether you need to move yet or outline a SQLite → PostgreSQL migration plan.
