SubTrackr

SubTrackr is a self-hosted subscription management application for tracking recurring services, visualizing spending, and receiving renewal reminders. It provides a lightweight web UI and an API for integrations, designed to run out-of-the-box with a single-file database.

Key Features

• Dashboard overview with real-time monthly and annual spending statistics
• Manage subscriptions with logos, categories, status, and recurrence schedules
• Calendar view showing upcoming renewals with iCal export
• Analytics and charts to visualize spending by category and time range
• Email notifications (SMTP) for renewal reminders
• Data export as CSV, JSON, or iCal and a RESTful API protected by API keys
• Multi-currency support with optional automatic conversion via an external rates API
• Themed responsive UI built with HTMX and Tailwind CSS; mobile-friendly layout
• Single-file SQLite database with Docker and Docker Compose deployment options

Use Cases

• Personal finance: centralize all recurring bills and subscriptions to monitor monthly spend
• Small teams: track shared service costs and export data for budgeting or reporting
• Automations: integrate subscription data into home automations or finance tools via the REST API

Limitations and Considerations

• Automatic currency conversion requires an external rates API and is subject to that provider's limits and base-currency constraints
• Uses SQLite by default (single-file DB), which is suitable for single-user or small deployments but may not scale for large multi-user or high-concurrency production environments

SubTrackr is focused on simplicity and ease of deployment, making it suitable for homelab and small-team use. It provides essential subscription management, export, and notification features while remaining lightweight and easy to run.
