Shares YNAB's exact profile: budgeting logic is clear, well-specified arithmetic. Live bank-account sync is the one piece worth respecting rather than hand-rolling.
VIBE SCORE 82/100
The parts this build actually needs, each rated on its own — the average is the Vibe Score above.

Two real costs, not just "free": the AI agent's own usage, and hosting once it's running. Both are estimated from this app's own effort rating and component list — see the assumptions on the method page.
| AI agent — with a subscription (Claude Pro/Max, Cursor, etc.) | $0 marginal |
| AI agent — pay-per-use API, no subscription | $43–$86 one-time |
| Hosting, once it's running | $10–$20/mo |
| Domain name, if you want your own | ~$12/yr |
Monarch Money costs $14.99/mo, but hosting alone could run $10–$20/mo — that can eat the whole subscription saving before the agent cost even comes into it.
Don't feel like building it? These are already made, open-source, and free.
Borderline. Shares YNAB's exact profile: budgeting logic is clear, well-specified arithmetic. Live bank-account sync is the one piece worth respecting rather than hand-rolling.
Monarch Money costs $14.99/mo (about $180/yr) as of 2026-08. That's what a working rebuild would save you.
Live bank-account sync (Plaid-style aggregation) is a serious integration and security surface — the same caution applies here as to every finance app on this register Shared household budgets with multiple users editing the same data add real multi-user complexity Automatic transaction categorization using machine learning is a real, separate feature beyond rule-based categorization
Yes — Actual Budget are open-source options worth trying before you build your own. Details are in the standard parts section on this page.
