Are there any self hosted finance/budgetting tools to manage tour personal incoming, project planning, saving accounts and expenses, that ideally have some integration to read transactions from banks to speed up the process?

I haven’t found one that did not require something like Tiller to create spreadsheets you can then import. I work with a lot of bank API in my professional life and they are very picky about who gets access directly to their API. I find it very doubtful anything open source would be able to do much without doing something like html screen scraping and that would severely limit how many banks would be usable as well as ensure it broke every time the html changed.
Plaid does offer developer access for personal accounts, so it’s possible. Plaid doesn’t cover all, but most. I’m building my own right now to self host since mint is going away…
Firefly III has some integrations, though requires some setup first plus third-party services. It should be possible to create a module to import via plaid though too (which I’ve found to be the most reliable of the lot so far).
