Hackable GUI SQL-manager written in SQL itself

Maybe reconsider the wording ”purest HTML” when the files being edited are in fact Jinja2 templates and the app uses non-semantic Bootstrap.

... and Python. ;)

Can you add/show some screenshots of the GUI

Yes, but how about real demo https://malewicz.herokuapp.com ?

The demo is a good idea, but a screenshot on the repo home page is probably a good idea too.

That way, people can get a rough idea of things without needing to click on anything further. Something like this maybe:

Thank you! I will create screenshot

This looks so pretty! Did you use any CSS framework for the fonts and layout?

Thank you! I have used standard bootstrap 5.1.3, sketchy theme from botswatch, chart.js and mermaidjs for diagram
