I have been looking for something like this for sometime. Right now I'm using YNAB with manual imports from bunq csv exports but I will give it a try and try out the bunq integration with firefly.

Does Firefly also support the features of YNAB, if you know by any chance?

It seems they do? Not compoletely polished.

--- EDIT: misread! I don't know about the _features_. They support importing, which doesn't imply supporting the features.

They claim they have budgets, 'categories', and something I wish YNAB had, 'tags'. Tags would be nice so that I could categorize expenses normally, e.g. 'restaurants', but also group them, e.g. 'trip to X'.

Bunq just introduced exactly that a week ago.

I have no idea what YNAB is but yes it is supported:

> You can also import from bunq, from YNAB, using FinTS or simply by uploading CSV files. [1]
