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 Paramapp alternatives, with the arithmetic →
What a replacement has to do
- Users add and edit subscription records; system stores billing period, payment method, notes, and next payment date; background scheduler triggers upcoming-payment reminders; currency conversion when showing totals; backups to Google Drive / CSV export; simple reporting UI for spend by category.
What it still won’t have
- Polished mobile apps or native installers (if the paid product includes them)
- Large user review base, brand and discoverability
- Priority support and SLA-backed support included in paid tiers
- Any proprietary telemetry, analytics, or built-in payment linking not documented on the public page
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a subscription-tracking web app using: React for frontend, TypeScript, Node.js + Express backend, Postgres for storage, Redis for scheduled jobs, and Docker for deployment. In scope: user auth (email+password, invite 3-seat teams), CRUD for subscriptions (title, amount, currency, billing period, start date, notes, tags), currency normalization using an exchange-rate API, background scheduler to compute next-payment dates and send reminder emails, Google Drive OAuth backup and CSV import/export, basic reports (monthly/yearly totals and category breakdown) and a minimal admin UI. Out of scope: native mobile apps, payment-processing of subscriptions, multi-tenant enterprise billing. Include error handling, automated tests for core API routes and scheduler, Docker compose for local dev, and CI steps to run tests.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
