Vercel is a platform that aims to simplify website deployment by allowing developers to deploy their websites with just one command: vercel. The platform provides GitHub and GitLab integrations, enabling teams to manage staging and production by merging pull requests. It also supports monorepo development for static websites and serverless functions within the same repository. Vercel dev is a single-command local development tool that automates the deployment process, eliminating tedious steps such as running processes, finding ports, and managing dependencies. With vercel dev, developers can enjoy live reloading of their code, making it ideal for modern frontend frameworks like Next.js and Gatsby. The tool also supports Go functions, static HTML, Node.js, Headless Chrome, and various other platforms and frameworks, making it a versatile solution for developers. Vercel dev is now available as part of the latest version of the Vercel CLI, with a dedicated feedback form and FAQ page to help users improve their experience.
