Best alternatives to mcdview in 2026
Explaining a database to a new teammate, or just remembering how your own tables connect six months later, usually means either digging through raw SQL or opening a heavyweight desktop modeling tool. mcdview skips both: you drop a schema file in, and it turns it into a clean, interactive diagram you can share as a link, with foreign keys and relationships drawn out visually. It accepts several common formats — raw SQL, Prisma schema files, pgModeler exports, and MySQL Workbench files — via drag-and-drop upload up to 5MB, and generates a shareable URL for the resulting diagram. For teams, it also plugs into CI/CD: you can wire it to regenerate the diagram automatically on each schema change, keeping a stable URL that always reflects the current state of the database rather than a stale screenshot from months ago. There's also an API for programmatic generation. It's an open-source project with its code public on GitHub, and ships with example databases (Pagila, Chinook, Northwind) so you can try it before touching your own schema.
