Not affiliated in any way with Actual Budget, but I can’t recommend it enough. It’s the FOSS version of YNAB pretty much so if you’re a fan of envelope budgeting it’s a great tool. I’d even say it has quite a few other strengths compared to YNAB (free bank syncing in the EU with more banks supported for example), and you can always be sure that your financial data stays within your reach.
Has worked really well for me. Like I mentioned I’ve had a couple instances where the banks change their login flow and I had to open a support ticket to get it fixed, but they (SimpleFIN) were very responsive in working on it when I opened a support request and had it fixed within a couple days. Two of my accounts also have to be re-authenticated every time I wanna pull data into Actual, but that’s also the banks’ fault and it’s not that big of a deal to do.
As for integration with Actual is basically flawless and just works. Setup is super easy, just paste in a token from SimpleFIN and boom you see all the accounts you have linked and can attach them to accounts in Actual. Sync is rock solid too, I don’t have any issues with it messing up transactions with duplicates etc.
