Git branching strategies are a perennial source of debate. The right answer depends on your team size, release cadence, and how much you trust your CI pipeline.

Trunk-Based Development

The simplest model: everyone commits to main (or a short-lived feature branch that merges within a day or two).

Works when:

  • Your CI/CD pipeline is fast and reliable
  • You have good test coverage
  • You deploy continuously
  • Your team is small to medium (2-20 developers)

The key practice is small, frequent merges. A feature branch that lives for a week defeats the purpose. Aim for branches that last hours, not days.

git checkout -b feat/add-search
# ... work for a few hours ...
git push origin feat/add-search
# Open PR, get review, merge same day

Feature flags handle incomplete features:

if (flags.isEnabled("new-search")) {
  return <NewSearch />;
}
return <OldSearch />;

GitHub Flow

A slight variation: main is always deployable, feature branches are reviewed via pull requests, and deployments happen on merge.

This is effectively trunk-based development with mandatory code review through PRs. It’s the default for most open-source projects and works well for teams that want review gates without heavy process.

GitFlow

Multiple long-lived branches: main, develop, release/*, hotfix/*, feature/*.

Works when:

  • You ship versioned releases (desktop software, mobile apps, on-prem)
  • Multiple versions are maintained simultaneously
  • You need a staging branch for release preparation

Doesn’t work when:

  • You deploy continuously
  • Your team is small
  • You value simplicity

GitFlow adds real overhead. Don’t use it unless you need its specific capabilities.

Practical Guidelines

Regardless of which model you choose:

  1. Protect main. Require passing CI and at least one review.
  2. Keep branches short-lived. Merge conflicts scale exponentially with branch lifetime.
  3. Automate mergeability checks. Use auto-merge when CI passes and approvals are met.
  4. Rebase or squash before merging. A clean history is easier to debug with git bisect.
  5. Delete merged branches. Stale branches are noise.

The best workflow is the simplest one your team can execute consistently. Start with trunk-based development and add complexity only when you hit a real problem that demands it.
