Frequently Asked Questions

Is this real PostgreSQL?

Yes, PGlite is PostgreSQL compiled to WebAssembly, supporting real PostgreSQL syntax including advanced features like CTEs, window functions, and JSON operations.

How much data can I store?

Browser memory limits apply (typically 2-4GB). This is ideal for learning and testing, not production data storage.

Are PostgreSQL extensions available?

Basic PostgreSQL is available. Some extensions may not be supported in the WebAssembly environment.

Is my data saved?

Data persists in your browser session. Closing the browser clears the database. Export your data or schema to save it.
