What is TrackSub?

TrackSub helps individuals and SMBs track recurring costs in one place. With TrackSub, SMBs can forecast future spend and get alerts before payments hit. I spent a few months building the app and launched in mid-2024.

Features:

• Support for 160+ currencies — live FX rates via a dedicated API for accurate global spend tracking.
• Slack alerts — pushes upcoming-payment and card-expiry reminders straight to any Slack channel (or email).
• Stripe Billing — self-serve plans, upgrades/downgrades, and secure billing-info updates.
• Google one-tap auth — frictionless sign-up and sign-in.
• Intercom chat — in-app support for users, wired to the ops team’s inbox.
• Automated background jobs — daily checks for due payments and expiring cards; notifies users in < 5 min.
• CI/CD container deploys — GitHub Actions builds, tests and ships to a Dokku-managed VPS.

Why Did I Build It?

After yet another forgotten subscription hit my card, I realised that I had no simple view of all my subscriptions. A quick audit of my bank account showed 10+ active services, half of which I barely used. So I built TrackSub to scratch that itch and help others facing the same problem.
