Sub-second artifact deployments are now supported in Vercel CLI

Vercel CLI version 59.16.0 introduces support for deploying static artifacts in under one second, allowing users to share prototypes or preview pages rapidly. The update targets deployments of HTML, HTM, and MD files, which Vercel automatically detects as eligible for immediate deployment without a build step. Running vercel deploy triggers the process, returning a live URL as soon as the artifact is validated. This feature is designed to streamline workflows for developers and agents generating static content.

The deployment acceleration applies to artifacts created by coding agents or manually generated files, enabling near-instant sharing and previewing. Vercel’s system identifies valid static files and bypasses the build pipeline, reducing deployment time to sub-second intervals. Users can update their CLI to version 59.16.0 or later to access this functionality. The command vercel deploy remains the primary method for initiating these deployments.

Supported file extensions for sub-second deployments include .html, .htm, and .md, covering common static formats used in web development. Vercel’s automatic detection ensures only eligible artifacts proceed directly to a live URL, while others follow the standard deployment process. The update enhances efficiency for rapid prototyping and iterative testing, particularly in agent-driven workflows. Documentation and additional options can be accessed via vercel deploy --help.

Vercel emphasizes the practical impact of this feature for teams and agents requiring fast artifact sharing and preview capabilities. The sub-second deployment capability is now available in Vercel CLI version 59.16.0 or later, with no additional configuration required for supported file types. This improvement aligns with Vercel’s focus on optimizing deployment speed for static content. Users are encouraged to update their CLI to leverage the new functionality.
