Lunch Money

A competent developer can recreate a useful CSV/manual-import budgeting app and dashboards in ~30 hours, but reproducing Lunch Money’s bank sync, crypto tracking, polishing, and hosted convenience makes keeping the paid product reasonable.

Open-source builds that already do this

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All Lunch Money alternatives, with the arithmetic →

What a replacement has to do

  • A minimal self-hosted replacement would ingest transaction data, store and categorize it, present simple analytics and budgeting, and allow CSV imports and manual entry.

What it still won’t have

  • Automatic bank sync / account aggregation
  • Crypto portfolio live sync
  • Mobile companion apps and polished UI
  • Hosted backups, dedicated support, and community programs
  • Long-term feature roadmap and price-lock guarantee

Runnable build prompt

Build a minimal single-tenant personal-finance web app using Next.js (React) frontend, Node/Express API, and Postgres database deployed to Vercel/Heroku. In scope: CSV and manual transaction import, transaction schema and category/tag model, simple rules engine for auto-categorization, per-user budgets, monthly spend/net-worth dashboards, basic multi-currency conversion (use a free FX API), developer JSON API endpoints for imports/exports, user auth (email + password, optional 2FA), migrations, error handling, and unit/integration tests. Out of scope: automated bank aggregation (Plaid/Ynab connectors), native mobile apps, crypto exchange integrations, advanced analytics, and paid hosting SLA. Include automated tests, input validation, logging, and scripted DB backups.
