Nice! An actual competitor to Airtable. Impressive.
Grist
Modern, open-source self-hostable spreadsheet software usable as website or as desktop application that stores data in SQLite databases
Interesting. I use spreadsheets for a lot of quick and dirty stuff, and I wonder if the constraints would be a problem.
There is an "any" data type that allows anything you want, it can be strict but only if you want it to be unlike a normal SQL database.
Grist is a modern relational spreadsheet. It combines the flexibility of a spreadsheet with the robustness of a database.
Now I know that a lot of people use spreadsheets as databases, so is this playing to that anti-pattern?
Some people compare it to Microsoft Access but it doesn't really feel that way. You can create forms to add rows but those are just intended to be shared externally for surveys, not data entry. It is far better at linking data between tables and has a strong focus on creating charts for said data.
I personally use it for several things such as keeping track of items like cables etc.
