This is very nice :) I was working on a proof of concept similar to this to have a quick search functionality for FrankenJura (german hiking database) but it was lost in a drawer due to lack of time 😁 Great work and thanks for sharing it :)
Did you see this already? :)
Fintunes is also nice :)
ActualBudget has auto import for banks and works well in general if you‘re into envelope based budget‘ing :)
Not really self hosted, but maybe splid.app is what you‘re looking for :)
Ghostfolio perhaps? :)
Kudos to the developer. It really is the right thing to do when services shut down.
If you don‘t mind, you could share the solution in the ActualBudget community once you have it :)
If I recall correctly, I couldn‘t find API endpoints back then and had to browse/prse the pges based on the regions and the links on the landing pages 😅
