What Is Vercel? The Front-End Deployment Platform
Vercel is a deployment platform for front-end frameworks and serverless functions, known for Git-connected deploys, preview URLs for every pull request, and a global edge network.
Vercel, the company behind Next.js, makes deploying modern web apps almost frictionless. Connect a Git repository and every push builds and deploys automatically, with a unique preview URL per branch or pull request. It handles building, hosting, a CDN, and serverless or edge functions so you do not assemble that stack yourself.
Git-driven deploys
Vercel connects to GitHub, GitLab, or Bitbucket. Pushing to a branch triggers a build and a deploy; merging to the production branch promotes to production. There is little to configure for common frameworks because Vercel detects them.
Preview deployments
Every pull request gets its own live preview URL, so reviewers and stakeholders can click through real changes before merge. This is one of Vercel most loved features and a strong fit for review workflows.
What Vercel runs
- Static and server-rendered front-end apps.
- Serverless and edge functions for backend logic.
- A global CDN with automatic HTTPS.
Vercel vs assembling it yourself
You could replicate Vercel with S3, CloudFront, and Lambda, but Vercel bundles the build, hosting, CDN, and functions into one product with great defaults. The trade-off is less control and a platform-specific model.
Role in CI/CD
Vercel itself acts as CI/CD for many teams: build, preview, and deploy on push. Teams that want extra control run tests and checks in GitHub Actions first, then deploy via the Vercel CLI or let the Git integration handle it. Required status checks can gate a merge before production deploys.
Key takeaways
- Vercel deploys front-end apps and serverless functions straight from Git.
- Every pull request gets a live preview URL for review.
- It can be your whole CI/CD, or pair with GitHub Actions for extra checks.
