Hi Product Hunt! We’ve all been there: you sign up for an AWS free tier or a 14-day SaaS trial, enter your credit card, and completely forget about it. A few months ago, a forgotten service tried to charge an empty card of mine. The transaction declined, and my bank hit me with a ridiculous penalty fee. That was the moment I realized I had absolutely zero clue how many random websites actually had my credit card info on file. I looked for a solution, but every subscription tracker out there required me to link my actual bank account. I didn't want a heavy budgeting app scraping my financial data just to tell me I pay for Netflix. I just wanted a simple, private way to map out where my cards were exposed. So, I built Catch Charge. It’s a minimal, privacy-first web app (installable as a PWA) designed to do one thing perfectly: track your card exposure and kill the "free-tier trap." I built this to scratch my own itch, but I know this community spins up free tiers and tests new software constantly. I hope Catch Charge can save you from a few surprise charges (and bank fees)! I would absolutely love some feedback from this community on the UI, the workflow, or let me know what features you'd like to see next! I'll be hanging out in the comments all day to answer questions.
