Show HN: A $1/year credit card keep-alive service
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. ;) A few years ago I was surprised to learn that people in the USA usually use credit cards instead of debit. Now I'm surprised to learn that it's not extreme if the number of cards they own reaches double digits. What about a subscription to send random stickers instead of plain nothing?
