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).
