DbSchema vs QuickDBD

DbSchema is a desktop tool for designing, documenting and working with SQL and NoSQL databases on Linux, macOS and Windows. It connects to more than 70 databases through JDBC and can download the needed driver. Users can build interactive schema diagrams, split designs into subsystem diagrams, or create physical schemas while offline and save them as local.dbs files. For connected databases, schema synchronization compares the model with the database and can produce migration SQL for review. The SQL editor offers schema-aware autocomplete, and a visual query builder lets users arrange tables, joins and filters and inspect generated SQL before execution. DbSchema can also publish interactive HTML5 schema documentation that opens in a browser without an installation or license. Connections run directly from the user's computer to the database, with configured SSL and SSH tunnels available. Community Edition is free forever. Pro Monthly is $29.40 a month, and Architect Monthly is $47.04 a month, plus taxes. The shared installer requires no registration and includes a 15-day Architect trial that can be extended by 15 days.

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. After downgrading, existing diagrams become viewable but not editable, while a Free user can create one editable diagram limited to 10 tables. QuickDBD is made by Dublin-based Dovetail Technologies Ltd and uses HTTPS for browser-to-server communications.
