You do not need a Kubernetes cluster. You need a branch protection rule, a working build check, and a deployment that does not break when you push a typo. Here is the minimum viable CI/CD stack for a solo founder shipping on Vercel.
Continuous integration and continuous deployment — CI/CD — is frequently presented as a complex DevOps discipline requiring dedicated infrastructure engineers and significant tooling investment. For a solo founder or small team shipping a web application on Vercel, the reality is much simpler. The minimum viable CI/CD stack requires three things: a version-controlled repository, an automated build check, and a deployment pipeline.
The repository is GitHub. Every change to your application goes through a commit and a pull request. This is not bureaucracy — it is the mechanism by which you can reverse any change, understand what changed when something breaks, and review code before it reaches your users. A repository without branch protection is a repository where a typo pushed directly to main can take your application offline.
The build check is Vercel's automatic build verification. Every pull request triggers a preview deployment. If the build fails, you see it on the pull request before it merges. If it succeeds, you get a live preview URL to test the change. This costs nothing additional on Vercel's free tier and catches the majority of deployment failures before they reach production.
The deployment pipeline is the GitHub-Vercel integration. Merging a pull request to main automatically deploys to production. There is no manual step, no SSH session, no FTP upload. The deployment is atomic — if it fails, the previous deployment remains live. If it succeeds, the new version goes live within sixty seconds of the merge.
This stack — GitHub repository with branch protection, Vercel preview deployments on pull requests, automatic production deployment on merge — is sufficient for the vast majority of early-stage web applications. It takes approximately thirty minutes to configure correctly from scratch. It is the exact stack we establish on every End-to-End Core Migration engagement, and it is what makes every subsequent change to your application safe to ship.
