Vercel BotID is an invisible CAPTCHA with no visible challenges or manual bot management required.

BotID is a new protection layer on Vercel designed for public, high-value routes such as checkouts, signups, AI chat interfaces, LLM-powered endpoints, and public APIs that are targets for sophisticated bots mimicking real user behavior.

Unlike IP-based or heuristic systems, BotID:

Silently collects thousands of signals that distinguish human users from bot

Mutates these detections on every page load, evading reverse engineering and sophisticated bypasses

Streams attack data into a global machine learning mesh, collectively strengthening protection for all customers

Powered by Kasada , BotID integrates into your application with a type-safe SDK :

Client-side detection using the <BotIdClient> component

Server-side verification with the checkBotId function

Automatic labeling of logs and telemetry for blocked sessions
