drawDB
drawDB designs database schemas and entity-relationship diagrams, then generates SQL for several database systems.
About drawDB
drawDB is an online tool for designing database schemas and entity-relationship (ER) diagrams. Users build diagrams on a canvas and generate SQL data definition language (DDL) for MySQL, PostgreSQL, SQLite, MariaDB, SQL Server, and Oracle. An existing DDL script can be imported to rebuild its diagram, and diagrams can be exported as SQL, DBML, JSON, or images.
The free editor runs in the browser without an account. Diagrams are stored locally in the browser, so they should be backed up before browser data is cleared. The homepage describes cloud storage, teams, and real-time collaboration as Pro features, and it lists an AI schema assistant without stating which plan includes it. drawDB is also open source and can be self-hosted with Docker on the user's own infrastructure.
