vercel dev

The vercel dev command is used to replicate the Vercel deployment environment locally, allowing you to test your Vercel Functions and Middleware without requiring you to deploy each time a change is made.

If the Development Command is configured in your Project Settings, it will affect the behavior of vercel dev for everyone on that team.

If you're using a framework and your framework's Development Command already provides all the features you need, we do not recommend using vercel dev.

For example, Next.js's Development Command (next dev) provides native support for Functions, redirects, rewrites, headers and more.

These are options that only apply to the vercel dev command.

The --listen option, shorthand -l, can be used to specify which port vercel dev runs on.

The --yes option can be used to skip questions you are asked when setting up a new Vercel Project. The questions will be answered with the default scope and current directory for the Vercel Project name and location.
