Can you 'click together' CRUD apps with them though? Or you need to write XML? I did not check them for quite a while because everything that could've been 'no/lowcode drag & drop' was quite painful before.
I haven't tried their graphical builders, so I would definitely classify Odoo as "low code" not "no code". The Python and XML needed to produce a basic list/form type CRUD app is, IMHO, minimal when you consider the features that you get in the app (paging, filtering, sorting, grouping, spreadsheet import/export, comment thread, notification, etc.). And that's w/o considering the many plugins available that can be used together with your custom modules.
BTW, egow here. Spot of trouble with my password on that login name.
