Open Source Subscription Tracker
Most subscription trackers ask you to trust a closed-source app with your financial data. Suprascribe publishes its full source code on GitHub, finds subscriptions by scanning email instead of your bank, and charges once - not every month. Self-host it if you want total control.
Open Source vs. Closed-Source Trackers
With a subscription tracker, "trust us" is not the same as "check for yourself."
| Feature | Suprascribe | Closed-source apps |
|---|---|---|
| Source code available | Full code on GitHub - inspect exactly what runs | Closed source - you trust a black box |
| Self-hostable | Run it on your own infrastructure | Vendor-hosted only |
| Bank account access required | Email scanning, never your bank | Many require Plaid access |
| Recurring fee | One-time Pro upgrade only | Most charge monthly or per seat |
| Privacy verifiable | Claims are checkable in the code | Take the privacy policy on faith |

Why Open Source Matters for a Subscription Tracker
A subscription tracker sits close to sensitive data - your email, your spending, the services you rely on. With a closed-source app, every privacy promise is something you have to take on faith. With open source, you can read the code and confirm it.
Verifiable privacy. Suprascribe claims it never stores email content and only scans subscription-related messages. Because the source is public, that is not a marketing line - it is something you or any engineer can check line by line on GitHub.
No lock-in. You can export your data, and because the project is open source you can self-host it entirely on your own infrastructure. Your subscription data never has to leave systems you control.
One-time cost, not a rented tool. Open source and a one-time Pro purchase go together: you are not renting access to your own data month after month. Pay once, own it, self-host if you ever want to.
What you get
- • Full source code on GitHub - auditable and self-hostable
- • Email-based discovery - no bank account access, ever
- • Unlimited free tier; Pro is a one-time purchase, no recurring fee
- • Data export and, if you self-host, total data control
Prefer not to self-host? The hosted version runs the exact same open code, so the privacy guarantees are identical.
