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.

use the first four words from your title as search terms in the search field and you'll get plenty of threads

ActualBudget has auto import for banks and works well in general if you‘re into envelope based budget‘ing :)

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).
