A solo dev built an ER diagram tool that never sends your SQL anywhere — then a data engineer said it isn't ER (sqltoerdiagram.com)
Tired of tools with paywalls, signups, or servers that swallow your schema, robhati built sqltoerdiagram.com: a client-side canvas where pasted DDL becomes an interactive diagram you can drag, auto-arrange, and export as PNG or SVG.
The engineering flex: tables are rasterized into cached bitmaps with viewport culling, and the SQL parser tracks source spans so a rename stays surgical. The pushback: tables aren't entities, so SQL alone can't give you a real ER diagram.
