hi michael, plato does look interesting, but probably won't fit my needs. i'm replying here rather than over email because the reason why brings up another interesting point - pretty much all the datagrid tools in the low/no-code space seem to be focused on the "company's internal tools" use case, where you have a few admins who need access to the raw data in the database and want a nice UI to edit it with.

what i'm trying to build is a multi-user version of a desktop app, so while i'm not really opposed to paying for a good tool (albeit at a nonprofit-friendly tier :)), per-user pricing is a non-starter, as is the high cost of self-hosting.

by way of comparison, the current "product" is a google sheet with an attached script file, and when someone wants to use it, i just send them a link to clone the sheet, and they have their own instance that they can share with whoever they like, setting read/edit permissions entirely by themselves. even if the non-google-sheets version ends up being something i need to host myself, i would like to replicate that level of ownership, where a group of users can create their own isolated instance and control its sharing and lifetime themselves.

what i'm looking for is not so much low-code, but a collaborative grid component that i can use as a primary user interface, either to drop into my app (if sufficiently modular) or build the rest of my app around (if sufficiently extensible). i am just a bit astonished that no one else, open source or otherwise, seems to have had the same need.
