Support sql2erd

Last updated 3 September 2026

sql2erd is free, has no account, no ads, no analytics and no trackers — and it stays that way. Nothing on this page is required to use the tool, and the tool itself never asks. If it saved you an afternoon of drawing boxes, this is where you can say so.

Nothing on this page is loaded from a third party. The codes are images served from this domain and the links are ordinary links — no payment widget, no iframe, no tracker, no analytics. That is deliberate: a donate widget would let a payment provider see every visitor, which would make the privacy policy untrue. Opening a link takes you to that provider, and only then does it see you.

Bank transfer or MoMo

Scan with a Vietnamese banking app or with MoMo. Both codes follow VietQR, which is a domestic standard — an app from outside Vietnam generally cannot read them.

Nothing here is expected — the tool is free either way. The amount each code proposes is noted under it.
