Vercel CLI as a “building block” for agents: sandbox, feature flags, curl and native binaries

Vercel CLI is evolving beyond a simple deploy tool into a programmable control layer for sandboxes, feature flags, and HTTP testing.

New capabilities include creating and reconnecting to isolated sandboxes, managing rollout percentages with Vercel Flags, and testing endpoints with a redesigned vc curl.

Vercel is also experimenting with native binaries to make the CLI faster and more consistent across operating systems.

The changes could improve safety and speed in agent- or CI-driven delivery pipelines.
