## Postgres Sandbox

Postgres Sandbox (postgres.new) spins up real PostgreSQL databases directly in your browser using PGlite. Write SQL and a fresh database is created automatically — no install, no server. It pairs that sandbox with AI assistance for generating SQL, plus support for CSV import, charts, ER diagrams and semantic search experiments.

**Preise und Tarife:** Free. Postgres Sandbox runs in the browser at no cost — there is no install, no account requirement mentioned and no paid tier advertised. Just open the page and a PostgreSQL database is created as you start writing SQL.

- **Instant in-browser Postgres:** A new PostgreSQL database is created automatically in your browser via PGlite — no server, no installation, no configuration.
- **AI SQL generation:** An AI assistant helps generate and reason about SQL from natural-language prompts, lowering the barrier for schema and query work.
- **CSV import:** Load CSV data and start querying it directly, which makes the sandbox handy for quick analysis and data exploration.
- **Charts and ER diagrams:** Turn query results into charts and draw ER diagrams to visualise table relationships within the same workspace.
- **Semantic search and RAG:** Explore RAG and semantic-search style workflows against your data, using the sandbox to prototype AI data features.
- **Real Postgres semantics:** Because it is real PostgreSQL, SQL you write here behaves like SQL you write on a server, so results transfer.

**Stärken:** Runs real PostgreSQL with no install or server setup; AI assistance lowers the learning curve for SQL; CSV import, charts, ER diagrams and semantic search in one place; Genuinely free and instant to try in the browser

**Einschränkungen:** Data lives in the browser session, so it is not a persistent production database; Persistent storage depends on browser/IndexedDB and can be cleared; Not a substitute for a managed Postgres server for real applications; AI-generated SQL should still be reviewed before running
