What's NewCopy Anchor Link

User-facing updates to Vercel Experiments - new labs, docs features, and notable changes.

October 12, 2026Copy Anchor Link

• Experiment surfaces (not every lab is an API) - docs and registry now default to UI Reference; Route Handlers only when HTTP, secrets, or ImageResponse need them. Added registry surface (ui | route-handlers | mixed). Pruned thin JSON wrappers from CDN Redirects, Favicon Brand Kit, and Thumbnail Factory; Vercel Flags local mode is UI-only; AI lab docs use Server Reference.
