I vibe coded an LM Arena for AI companion apps with Claude Code.

I can't write code. I've never written a line of it by hand. I still wanted something that didn't exist: a leaderboard for AI companion sites that shows what was tested, when, and how many people voted. Most "Top 10 AI girlfriend apps" pages are affiliate lists with a number stuck on top. LMSYS Chatbot Arena does it properly, so I described that to Claude Code and we built it: seven leaderboards with community voting and dated monthly snapshots. Astro, Cloudflare Pages Functions, D1. No accounts, no login, no client framework. Voting is a static page and one POST. Two things I learned from specifying all of it and writing none of it. Every site on the board wants to stuff the vote They all pay me affiliate commissions, so they all have a reason to send fake votes. Ballots over the rate limit don't get rejected. They get written like any other ballot, they just never reach the table the score reads from. If I rejected them I'd have no record, and I couldn't tell you lat
