Chat2DB

Chat2DB, open-sourced from day one under Apache 2.0 and maintained by codePhiliaX with 1 million+ users, converts natural-language questions into SQL and provides a unified interface for connecting to, querying, and managing 30+ database types including MySQL, PostgreSQL, MongoDB, Snowflake, and Oracle. Beyond text-to-SQL, it offers visual GUI-based data management, import/export handling CSV, XLSX, and SQL files up to millions of rows, AI-generated dashboards and charts with "chain reasoning," and security features including SSH tunneling, AES/RSA encryption, two-factor authentication, and SQL audit logs. A working web platform (app.chat2db-ai.com) and downloadable desktop clients are both available; the core project is free and open source, with pricing tiers referenced (including a mentioned student discount) for hosted/premium features. Good fit for a developer or analyst who works across multiple database types and wants natural-language querying and visual management in one open-source tool rather than a separate client per database.
