FamilyJar – privacy-first budgeting app for couple
Goodbudget and Honeydue already serve couples with envelope budgeting features.

YNAB meets portfolio tracker in one dashboard, beautiful visuals, but early beta and unfamiliar brand.
Individual users, personal investors, people managing budgets and multi-asset portfolios simultaneously

I needed something that combined YNAB's envelope budgeting with what a multi-asset portfolio tracker does. For me, your budget and your investments are linked. Obviously, never invest more than you can afford to lose - but how are you supposed to know how much that is for you without understanding your spending habits?
So I built Finzen
Finzen = budgeting + portfolio tracking + rich visual reports and stats
Currently in free open beta.
Built with vue, vite, tailwind, typescript
AES-256 encrypted data storage, EU servers, No Bank Sync

I've been working on this since last July. Feels good to finally have something I can share! Feedback would be awesome. This is the first project I've ever actually finished!!!

German tax calculations with self-hosting when QuickBooks ignores Germany.
Offline-first bank import with ML categorization—real privacy, real product, shipped.
The YNAB import wizard is the product's strongest play — migrating your full history removes the biggest friction for switching. Keyboard-first shortcuts, shared budgets for up to five people, and a $40/yr base plan make it a practical, cost-focused alternative rather than a reinvention. It doesn't break new ground conceptually, but the feature set and migration tooling are exactly the pragmatic wins price-sensitive YNAB users care about.
Score budget redistribution for widget weighting beats manual dashboard config.
SQL API for AI agents, but YNAB and Monarch Money already handle AI-assisted finance.
