## What it is
PGlite is a WASM build of PostgreSQL packaged as a TypeScript client library that runs a full Postgres database in the browser, Node.js, Bun, and Deno with no other dependencies. It supports persistence to the filesystem or IndexedDB, reactive live queries, and Postgres extensions like pgvector and PostGIS.

## Use cases
- run postgres in the browser
- embed a local database in a javascript app
- fast postgres for unit and CI tests
- local-first app with realtime sync
- on-device vector search for RAG
- lightweight local postgres for development
- ephemeral in-memory sql database for edge functions

## When to choose
- you need real Postgres (SQL, extensions, pgvector) running client-side or at the edge without a server
- you want fast, isolated per-test Postgres instances in unit or CI testing
- you're building local-first or offline-capable apps with reactive queries
- you want a zero-install local Postgres for development

## When to avoid
- you need a production server-grade Postgres with multi-user concurrent access
- your app requires a database larger than browser memory/storage limits
- you need native Postgres performance or features not available in the WASM build
- your stack is not JavaScript/TypeScript
