Vercel BotID: The Invisible Bot Protection You Needed

Vercel BotID is an invisible CAPTCHA solution that protects web applications from sophisticated bots without disrupting real users. The tool uses lightweight browser signals to detect automated traffic in real-time, protecting critical endpoints like checkout flows, signup forms, and APIs. Implementation involves installing the SDK, configuring route protection on the client side, and verifying requests on the server using the checkBotId() function. BotID offers two modes: Basic Mode for all plans and Deep Analysis Mode with Kasada-powered detection for Pro and Enterprise users. The system maintains a directory of verified legitimate bots that can be selectively allowed, and developers can customize responses to failed checks ranging from hard blocks to soft failures.
