Connect v0 to Your Real GitHub Repo: AI-Generated Components That Go Through PRs, Not Around Them

v0's GitHub integration creates one branch per chat and never commits to main — generated UI lands as a PR you review like any other code change, not as a mystery diff in your working tree.

The common fear with v0: you prototype something useful and then face a pile of generated code with no clear path into an existing Next.js/React codebase. The February 2026 update added native GitHub integration that addresses this with a branch-per-chat workflow.

Setup

1. In v0's project settings, connect your GitHub account.
2. Create a new project → + → "Import from GitHub" → select your repo.
3. For private repos: grant v0 access in your GitHub App settings.
4. v0 creates one branch per chat session and never commits to main by design.

The workflow

• Every code change in v0 is an automatic commit on that branch.
• Create a PR directly from v0 — it goes through your normal review process.
• Pull the branch locally with git fetch && git checkout <branch> to inspect the generated code in your editor before merging.

Before merging, check for

• Does the generated component use your existing design system, or does it shadow it with its own Tailwind/MUI classes?
• Are prop types and import paths consistent with the rest of the codebase?
• Are there useEffect calls with missing or empty deps arrays where the actual dependencies weren't inferred?

After merge: hand off to Claude Code

The generated component is now in your repo and tracked by git. Run /code-review against the branch for a bug-finding pass, then iterate in your editor. v0 gets you to a workable shape; Claude Code closes the gap on correctness and integration.
