mcdview turns database schemas into shareable diagrams

Field notes

The tool accepts database model files or pasted SQL, then produces an interactive diagram that can be shared by link. The homepage lists a 5 MB upload limit and support for SQL, pgModeler, Prisma, DBML, Mermaid, Drizzle, and other formats. It distinguishes seven-day ephemeral pages from stable links intended for CI pipelines, where diagrams are regenerated during builds and can expose diagnostics or schema drift.
