What it does

Chat2DB gives you a visual SQL editor and AI‑assistant that can generate, explain, and optimise queries for any of 40+ databases, all running locally on your machine or in Docker.

When to use it
  • •You need a quick UI to explore a new database without writing SQL by hand.
  • •Your team wants AI‑generated queries or explanations directly in the query editor.
  • •You prefer a self‑hosted, free tool that works on Windows, macOS, Linux, or via Docker.
Ready-to-paste prompt
Generate a SQL query that returns order_id, customer_name, and total_amount for all orders placed in the last 7 days, sorted by total_amount descending.
Heads up: AI features require an LLM key; set the environment variable `CHAT2DB_OPENAI_KEY` (or configure another model) before using the assistant, otherwise the AI tab will stay disabled.
