Vercel's bot verification now supports Web Bot Auth
ChatGPT operators just got faster access to your site. Vercel's new Web Bot Auth lets AI agents prove they're legitimate—no IP spoofing, no blocks.

Why it matters
Vercel shipped Web Bot Auth to distinguish legitimate AI traffic (ChatGPT operators, SEO crawlers, monitoring tools) from spoofed bots using cryptographic signatures. This matters because AI agents operating in dynamic/serverless environments can now reliably access sites without being blocked, reducing friction for enterprise AI automation while maintaining security.
