SwipeRank - rank is earned, never bought

Hey Product Hunt 👋 outbid.lol launched a while back - a leaderboard where the #1 spot goes to whoever pays most. It did well, and a wave of clones followed, all with the same premise: rank is for sale. I wanted to build the inverse. SwipeRank is a swipe deck for SaaS products. You swipe right or left, and the score is Elo - every product starts at 1000 and moves with each swipe. The K-factor shrinks as volume grows, so an early burst of votes can't hold a score a product hasn't earned. You can pay, but only for exposure. A boost makes your card get dealt more often, capped at 4x, for a window you choose. It cannot move your score by a single point - and that's enforced in Postgres, not just promised in the copy. The score column rejects any write that didn't come from a swipe, so the boost code physically can't touch it. Anyone can back any product too, not just the owner. No accounts. Listing gives you a token that lives in your browser, and that token is the only thing that can edit it. $5 to list, one time. More a spam filter than a business model. It's early, and the board is small, so every swipe visibly moves things right now. What I'd most like to know: does the ranking feel fair once you've swiped through a few? Built with Claude Code.
