Chat2DB
Chat2DB is an open-source, AI-powered database client that transforms the way teams work with SQL. Starting with plain-language questions, it generates optimized queries, explains results, and automates data analysis, while its GUI-based workspace handles data editing, sorting, filtering, import/export, and dashboard sharing. It is designed to become the single place where you connect to any database type, eliminating the need to jump between multiple database tools.
The AI capabilities go far beyond simple text-to-SQL: a context-aware chatbot works across 10+ LLMs, fixes SQL errors in one click, and uses chain reasoning plus auto-generated charts for deeper analysis. Users can even teach the AI about their database by adding custom business terms in AI column comments, improving query accuracy over time. On the privacy side, Chat2DB emphasizes that data queries are processed locally and that only the database schema is referenced, not the actual data, so sensitive information stays under your control.
Built with an Apache 2.0 license, Chat2DB is one of the most popular open-source text-to-SQL tools on GitHub, used by over a million people. It supports relational and non-relational databases, handles large-scale data migration with millions of rows, and offers enterprise-minded security features such as encryption, SSH tunneling, two-factor authentication, least privilege access, and SQL audit. Whether you are a developer, data analyst, business manager, or total SQL beginner, Chat2DB provides a fast, collaborative, and secure way to turn data into decisions.
