You can now preview the framework preset and files that Vercel CLI includes in a deployment before creating one.

Run vercel deploy --dry from a linked project:

▲ vercel deploy --dry

Deployment Dry Run

Detected Framework Preset: Next.js (nextjs)

Included: 4 files, 3KB

Ignored: 2 paths

Path Files Size

public 1 2KB

src 2 1KB

.vercelignore 1 12B

Largest Files

public/hero.png 2KB

src/data.json 1KB

src/index.js 20B

.vercelignore 12B

Output includes framework detection, file counts, sizes, and largest files.

For automation or further inspection, return the complete file manifest as JSON:

vercel deploy --dry --format=json

JSON output includes the detected framework, included and ignored paths, directory size distribution, largest files, file modes, and content hashes. Piped and other non-TTY output automatically uses JSON.

Agents can use this manifest as a pre-deployment check, verifying framework detection, identifying unexpected or missing files, flagging oversized assets or unusual file modes, and updating .vercelignore or project configuration. Agents can rerun the check until the manifest matches the intended deployment, without uploading code or creating a deployment.

Update the Vercel CLI to v54.17.2 or later to get started. Learn more in the vercel deploy documentation.
