Pinned on this launch
I'm the founder of dbdiagramr. I built it because getting an ER diagram from a real Postgres database still means drawing tables by hand or opening a desktop app. Paste a read-only connection string and it maps your tables, foreign keys, and Supabase RLS status in under 10 seconds. No signup, nothing stored. This is v1. Try it on a real schema and tell me what's missing or confusing. I'll be in the comments.
About dbdiagramr
