Hey everyone! I built a simple tool that turns my subscriptions into a proportional treemap - bigger box = bigger monthly spend.
Seeing it visually was honestly a bit confronting. I knew streaming services cost money, but I didn’t realize they made up quite a lot of my total subscription spend until I saw them as massive boxs. Made it pretty easy to decide what to cut first.
What it does:
- Shows all your subscriptions as proportional boxes
- Instantly highlights which services dominate your budget
- Useful for deciding what’s actually worth keeping vs what to cancel
Privacy-focused:
- No signup required
- 100% free (personal project, I make nothing from this)
- All data stays in your browser - nothing sent anywhere

Would love feedback, is this actually useful, or am I the only one who needed to see it visually to take action? Open to suggestions on what would make it better.
