Preview Deployment
An automatic temporary deployment of a pull request branch, letting you test and share changes before merging.
A preview deployment creates a live, shareable URL for every pull request. Instead of asking a reviewer to check out your branch locally, they click the preview link and see the running application. When the PR is merged or closed, the preview is automatically cleaned up.
Vercel, Netlify, and Cloudflare Pages all offer automatic preview deployments. They detect new commits on a branch, build the project, and deploy it to a unique URL (like my-app-feature-xyz.vercel.app). This makes code review faster and catches visual bugs that are invisible in a diff.
For vibe coders, preview deployments are part of a professional workflow. AI helps you build features quickly, but preview deployments let teammates, designers, and stakeholders verify the result before it reaches production. Setting this up once saves countless "can you check this on your machine" conversations.
