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, 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.
