Is my data stored? Only the files it generates for you to download, for 1 hour; then they are deleted automatically. Nothing else is stored. See the privacy policy.
What can it not do?
- Up to 50 tables, 60 columns per table, 1,000 columns and 120 foreign keys in all, 200,000 characters of DDL
- Reads CREATE TABLE only; ALTER TABLE ... FOREIGN KEY and other statements are listed as skipped, not drawn
- A CREATE TABLE that does not parse in full is refused with the line number; it does not guess
- It does not connect to a database or run the SQL
- The PDF font covers Latin, Greek, Cyrillic and Vietnamese; Chinese, Japanese, Korean, Arabic, Hebrew and emoji show as ? in the PDF (the SVG, CSV and JSON keep them)
- Files of large diagrams are kept for 1 hour so the download links work, then deleted; download the files to keep them
