SubTrack

Simple subscription tracker for normal users.

Product promise:

See what you pay, when it renews, and what you could cancel.

SubTrack is a small v0.1 web app for manually tracking subscriptions and recurring payments. It is private, practical and intentionally simple.

What v0.1 includes

• Dashboard with monthly total, yearly total, active subscriptions and next renewal.
• Subscription list.
• Add, edit and delete subscriptions.
• Mark subscriptions as active, paused or cancelled.
• Mark a subscription as paid to advance its renewal date.
• Upcoming charges grouped by next 7 days, next 30 days and later.
• Simple insights:
  • most expensive subscription;
  • most expensive category;
  • monthly equivalent cost;
  • yearly projected cost;
  • possible savings from cancelling the most expensive item.
• Local SQLite database through Prisma.

Stack

• Next.js
• TypeScript
• Tailwind CSS
• Prisma
• SQLite

This stack keeps the app small, self-hostable and easy to run locally.

Data model

Subscription

• id
• name
• price
• currency
• billingCycle
• customCycleDays
• nextRenewalDate
• category
• status
• reminderDaysBefore

Install

npm install

Create a local environment file:

cp .env.example .env

On Windows PowerShell:

Copy-Item .env.example .env

Generate Prisma Client and create the local SQLite database:

npm run prisma:generate
npm run prisma:migrate

If Prisma Migrate is not available in your local environment, initialize the SQLite table directly with:

npm run db:init

Start development server:

npm run dev

Open:

http://localhost:3000

Scripts

npm run dev
npm run build
npm run lint
npm run typecheck
npm run db:init
npm run prisma:generate
npm run prisma:migrate

Privacy note

SubTrack v0.1 stores data locally in SQLite. It does not connect to banks, payments, emails, analytics or third-party tracking services.

Do not store sensitive information in notes. Use plain notes such as cancel through app store or annual plan renews in May.

Known limitations

• Totals assume the entered currency values can be compared directly.
• There is no currency conversion.
• There are no notifications outside the app.
• There is no authentication in v0.1.
• There is no import/export yet.

Roadmap

• v0.2: import/export CSV and better filtering.
• v0.3: optional local reminder jobs.
• v0.4: simple charts.
• v0.5: optional authentication for shared/self-hosted deployments.

No bank integrations, AI or payments are planned for the early versions.
