What is it?

SubTrackr is a self-hosted web application for keeping track of recurring subscriptions. It shows monthly and annual spending on a dashboard, offers a calendar of renewal dates with iCal export, and sends renewal reminders by email or Pushover. Data is stored in an embedded SQLite database, so no separate database server is needed.

The app is written in Go with the Gin framework and uses HTMX with Tailwind CSS for the interface. It is distributed as a multi-platform Docker image covering AMD64, ARM64 and ARMv7, and includes setup notes for Portainer, Unraid, Synology and Proxmox LXC. Currency conversion via Fixer.io is optional; without a key, subscriptions are shown in their original currencies.

SubTrackr exposes a REST API authenticated with API keys, and an MCP server so AI assistants such as Claude can read and manage subscriptions. Data can be exported as CSV, JSON or iCal.

Things to know

  • Currency auto-conversion requires a Fixer.io API key, and the free Fixer.io plan only allows EUR as base currency.

  • The README suggests adding a reverse proxy or auth layer for security, since authentication is optional.
