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.
I’ve literally just switched to Actual (3 days in) after living out of a homemade Excel YNAB clone for years and years. Overall it’s great and the bank syncing works really work.
I love that it’s open source, E2E encrypted, self-hostable and the data lives in a SQLite database.
If I haven’t found any major snags, I’ll of course become a supporter in a couple of weeks.
