DB-MAIN vs SchemaCrawler

Both stand on data modeling software. Which one you can start free with, which one lets you read the code, and what each costs once you pay.

SchemaCrawler provides a broad set of schema discovery, documentation, comparison, and diagramming options at no software cost. Note that some drivers and templating engines must be downloaded separately, and its security guidance places responsibility for scripts on users.
