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.

A new PostgreSQL database is created automatically in your browser via PGlite — no server, no installation, no configuration.
An AI assistant helps generate and reason about SQL from natural-language prompts, lowering the barrier for schema and query work.
Load CSV data and start querying it directly, which makes the sandbox handy for quick analysis and data exploration.
Turn query results into charts and draw ER diagrams to visualise table relationships within the same workspace.
結合自訂軟體與專門的專家團隊來處理複雜業務，但屬於量身訂製的服務。
提供先進的多模態資料策展與標註基礎設施，但標註工作需要自備人力。
