SubTracker — Subscription Tracker - Sell Project

SubTracker helps people track what they're paying for — Netflix, ChatGPT, Figma, gym memberships, all of it — in one place, with a live 12-month spend trend and a "you probably forgot about this" warning for subscriptions that quietly keep charging. Honest status: Pre-revenue, no live users. I built this end-to-end (frontend, backend, accounts, billing scaffold) to a shippable state, but haven't launched or marketed it. You're buying a finished, working product — not a business with traction — and it's priced accordingly. What's built and working: Full subscription CRUD: manual entry + automatic bank CSV import (matches 30+ known merchants — Netflix, OpenAI, Spotify, AWS, etc.) 12-month spend trend chart, category breakdown, stale-subscription warnings Multi-tenant accounts: email/password auth (bcrypt + custom HMAC tokens, no third-party auth dependency), subscriptions synced server-side per account Free tier works fully anonymously too — no account required, everything runs in the browser via localStorage Pro tier scaffold ($4.99/mo placeholder): unlimited CSV imports (free capped at 1/month), PDF export, and email renewal reminders sent 3 days before a subscription's next charge Stripe Checkout wired end-to-end, including the webhook that flips a user to Pro on payment — connect your own account and it should work as-is Email reminders run on a daily cron via Resend — connect your own API key Light/dark theme, fully responsive Live demo: https://subtracker.siftx.io (loads with sample data so you can see it working immediately) What's NOT done — the buyer's job: Distribution and marketing — the product is finished, it has zero users Stripe and Resend are built against the standard APIs but not verified against a live account (no access to test from my region) — should work as-is, budget an hour to confirm No mobile app / browser extension for auto-detecting subscriptions — CSV import is the current mechanism Tech stack: React 19 + Vite + Tailwind v4 + Recharts + jsPDF (frontend). Express + better-sqlite3 + node-cron + Resend + Stripe (backend). Items being sold: Full source code (frontend + backend), no domain.
