QuickDBD is a web tool for drawing database diagrams by typing schema details. It supports SQL export, forward engineering and collaboration, with database support for MySQL/MariaDB, SQL Server, PostgreSQL and Oracle 12c+. The service is free to try without registration, and diagrams can be shared online. Diagrams made with a Free account are publicly accessible; Pro users can mark diagrams private. The Basic plan provides one diagram with up to 10 tables per diagram. Pro costs $7, paid once, billed once-off for one week, and includes 10 diagrams with any number of tables per diagram.
