Hey everyone! 
I’ve been searching for a way to track my finances without relying on third-party paid services. When I found “Maybe Finance”, an open-source personal finance app that does exactly what I wanted! Since it wasn’t available for Home Assistant, I ported it as an add-on to host alongside HA.
Why Maybe Finance?
There’s already Actual Budget (forum post here), which is great for envelope budgeting. But I was looking for a different feature set.
Maybe Finance vs. Actual Budget – Feature Comparison
| Feature | Maybe Finance | Actual Budget |
|---|---|---|
| Self-Hosted |  Yes |
Yes |
| Multi-Currency Support | Yes (Didn’t test it) |
 |
| Credit Card Handling | Handles balances & payments |
 Basic support |
| Investment Tracking (Stocks, Crypto) | Yes |
No investment tracking |
| Budgeting |  Basic budgeting (Very new feature) |
 Designed for envelope budgeting |
| Net Worth Tracking | Historical tracking |
No built-in net worth tracking |
| Financial Insights & Ratios | Debt-to-income, runway, etc. |
Limited financial metrics (Although the graphs are better at the moment.) |
| CSV Import | |
|
| Automated data import (All provider need manual setup if selfhosted) | Using Plaid (Supports US & EU, but not UK yet |
GoCardless (European Banks) & SimpleFIN Bridge (North American Banks) |
Keep in mind that Maybe is a very new player and is still a WIP. So some features are not stress tested/finished.

Feedback
This is my first Home Assistant add-on! It works on my dev machine and my main instance, but I can’t guarantee that:
It works perfectly for all setups
It follows best security practices (especially for backups)
