A developer shares how 412 fake accounts were created overnight despite layered defenses, leading them to adopt Vercel BotID. The post explains how BotID works: a self-mutating client-side JavaScript challenge that regenerates on every deploy, making reverse-engineering economically unviable for most attackers. It covers Basic (free) vs Deep Analysis (paid, $1/1000 calls via Kasada ML) modes, a Next.js integration code example, the isVerifiedBot field for allowing legitimate crawlers, and honest tradeoffs including vendor lock-in, false positive rates (~0.1%), and async verdict updates. Recommended for protecting account creation, AI inference, and checkout routes on Vercel-hosted SaaS.
