The budget spreadsheet nobody keeps up to date
Almost everyone has started a budget spreadsheet. Almost nobody keeps it: formulas break, categories don't fit, and the simple question — “are we on track this month?” — takes ten minutes of reconciliation.
Banking apps sort automatically… into their own categories. “Miscellaneous” swells, the couple's shared expenses blend into personal ones, and you still don't know who owes whom what.
Your way of counting, described then generated
Describe your setup: “We want to track the couple's budget. Some expenses are shared (rent, groceries, outings), others personal. Each expense has a category, an amount, a date and who paid. I want a monthly budget per category, to see what's left, and who fronted the most so we can rebalance.”
Blueprint Maker generates the matching application: expenses with their categories, the shared / personal distinction, per-category budgets, and a dashboard answering your questions — left to spend, balance between the two of you, categories running over.
Your categories, your accounts, your sharing logic become the structure of the application.
- Expenses with category, amount, date, payer
- Shared vs personal expense distinction
- Monthly budgets per category
- Who fronted what — couple balance
- Dashboard: left to spend, overruns
Private, on your URL, no bank connection
The application doesn't plug into your bank accounts: you enter what you want to track, and nothing else leaves. No aggregator, no sharing of your banking credentials with a third party.
It's a web application at your dedicated address: reachable from the phone, shareable within the couple, the same data for both of you.
Free to start, genuinely owned
The Discovery plan (€0) generates a first complete application. Paid plans are for iterating, with the cost shown before each generation.
The code is exportable: your budget tracking belongs to you. No reselling of your financial data, no ads — a tool, not a loss leader.

Frequently asked questions — budget tracking
Does the app connect to my bank?
No, by design: you enter what you want to track. No banking credentials are requested or shared with a third-party aggregator.
Can two people use it, for a couple's budget?
Yes: it's a centralised web application, the same data for both of you. The shared / personal distinction and “who paid” are described in your request.
Do I need technical skills?
No. You describe your way of counting in plain language, validate a plan, and the application is generated — without writing code.
Can I adapt the categories to my situation?
Yes: it's YOUR categories that structure the application, since it's your description that generates it — not an imposed list.
Is my financial data safe?
The application belongs to you (exportable code). You can keep it as is or self-host it; there is no data reselling and no ads at the core of the model.
