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.
“That you can self-host” Does a budgeting tool need to be a service that’s constantly running and not an application? I struggle to see how having it running as a service on some box somewhere is going to help. “It’s so you can access it on your phone elsewhere.” Oh great. It’ll have a garbagepuke mobile UI.
In this case, the mobile UI doesn’t even work properly.
That said, I find value in it because it makes it so much easier for my SO and I to see the same thing. Oh, and it supports importing transactions via SimpleFIN, which is really nice.
