Git Branching Strategies

A branching strategy defines how your team collaborates through version control. The wrong strategy creates merge hell, blocks releases, and wastes developer time. The right one matches your team size, release frequency, and deployment model.

Everyone commits to a single main branch. Short-lived feature branches (< 1 day) are merged frequently.

Pros: Simple, fast CI feedback, avoids merge conflicts, enables continuous deployment. Cons: Requires good test coverage and feature flags for incomplete work. Best for: Teams practicing continuous deployment, any team size with mature CI/CD.

A lightweight model with one rule: anything in main is deployable.

1. Create a feature branch from main
2. Make commits and push regularly
3. Open a pull request for review
4. Merge to main after approval
5. Deploy immediately

Pros: Simple, PR-based review, works well with CI/CD. Cons: No concept of releases or environments. Best for: SaaS products, small-to-medium teams, continuous deployment.

A structured model with dedicated branches:

• main — production-ready code, tagged releases
• develop — integration branch for features
• feature/ — individual features, branched from develop
• release/ — release preparation, branched from develop
• hotfix/ — emergency fixes, branched from main

Pros: Clear structure, supports parallel releases, good for versioned software. Cons: Complex, slow, lots of merging overhead. Best for: Packaged software, mobile apps, teams with scheduled releases.

Ask these questions:

• How often do you deploy? Daily → trunk-based or GitHub Flow. Monthly → GitFlow.
• How large is your team? 1-5 devs → trunk-based. 5-20 → GitHub Flow. 20+ with multiple release trains → GitFlow.
• Do you need to support multiple versions? Yes → GitFlow. No → simpler models.

When in doubt, start with GitHub Flow and add complexity only when you hit real problems.
