All kinds of stuff. I use it when I need a way to structure my data:

• I use it to keep track of software / libs that are of interest, what they are an alternative to. See example here: https://ibb.co/ncsdt0W
• I’ve also tried to recreate the functionality of a personal relational management (a la MonicaHQ, or per this post: https://medium.com/@rklau/my-homegrown-personal-crm-87dffbcf54d7) but found it to be an overengineered solution.
• I also used it to interact and store data through my python apps, to avoid dealing with it directly in python.
• You can also use it as a Kanban board
• Also, I’ve been trying to use it as an excel replacement - which is an overengineered solution but you get impeccable dataquality.

Nocodb is a bit wonky, but it is quite easy to work with (front- and backend) and since everything is in the database format you choose - you’re in control of how you want your data.
