The most painful thing about taking over someone else’s project: opening the database, hundreds of tables, no documentation, no comments, and table names are pinyin abbreviations.
ChartDB solves this. Run a single SQL query to export the entire database structure and automatically generate an ER diagram — you can see at a glance which tables are related, how foreign keys connect, and so on.
No database password needed, no software installation, no account registration. It also comes with built-in AI — just ask in natural language, like “How are the user table and order table related?” and get the answer.
Supports MySQL, PostgreSQL, SQLite, and Oracle. Open source and free.
