Show HN: A $1/year credit card keep-alive service
https://keepalive.financeHey HN! I built the world's most boring SaaS - it charges your unused credit cards $1/year so banks don't cancel them for inactivity.
The problem: Banks cancel credit cards after 6-24 months of no activity. When they cancel your oldest card, your credit score can drop 50+ points due to reduced credit history length and lower total available credit.
The solution: KeepAlive automatically charges each card $1 annually. That's it. That's the entire product.
Why this exists: I personally wanted it & Claude Code.
Tech: js, supabase, stripe

Yes, I know this is absurd, but I've actually been using a version of this for a couple years now and decided to vibe code it up now that anything is possible. ;)
