It depends.

Have you tried GNU Cash?

I use Beancount All categorization is manual, but it is quite versatile. I like that it is just plain text.

For visualization there is Fava

For a while I was tracking my expenses in a LibreOffice Calc sheet since they are not complex, but I heard positive things about these two from other users:

For expense tracking: Actual Budget

For investments: Portfolio Performance, Ghostfolio

I just use a spreadsheet currently. No fancy template or anything basically just a monthly expenditures list into a few categories.

I used/liked Goodbudget (an app based simulation of an ‘envelope system’) for a while. I think it was especially helpful for developing budgets across moves if that makes sense. Not sure what their free features look like nowadays but before you could share it between people so your whole household could see how much was available in the “groceries” ‘envelope’ for example and move money from another ‘envelope’ if they needed more.

I must mention this FOSS app! https://github.com/danilkinkin/buckwheat

I use this to track my monthly spend with my cards that I manually swipe at stores. This is the only budgeting app that has stuck with me for quite some time.

I personally use Kitchenowl with my partner because you can share expenses between household members and set whatever percentages you want, and you can also create your recipes and shopping lists, so it's really handy for using with roommates etc.

I use a spreadsheet and write down everything I buy and manually categorize into about 8 categories. Simple and effective for keeping me on track w.r.t. my financial goals.

MyExpenses is what I use. Simple, allow for reconciliation with bank and to easily export if needed.

Sure, but I've only started recently so not sure how it'll hold up. I've managed to get my bank transactions in there and my investments as well, and for a brief period my crypto too. It all needs external integrations though (or you can do it by hand).

It does have tags and rules to automate some categorisation. There are a few people maintaining it but it obviously came with some tech debt too (it was originally developed by a company and called maybe, they open sourced it when they gave up on it).
