Branching strategies in Git: GitFlow, Trunk-based development, and others

There are several popular branching strategies in Git that help organize the development and release process:

1. GitFlow

   • Main idea: use several types of branches — master (production), develop (integration of new features), feature/*, release/*, hotfix/*.
   • feature branches are created from develop for developing new features.
   • After completion, features are merged into develop.
   • A release branch is created for preparing the release, where final testing and fixes are performed.
   • hotfix is for urgent fixes in production, created from master.
   • Suitable for projects with a clear release cycle and many participants.

2. Trunk-based development

   • The entire team works with a single main branch — main or trunk.
   • Features are developed in short-lived branches or directly in main using feature flags.
   • Frequent commits and integrations reduce conflict risks.
   • Suitable for CI/CD and rapid deployment of changes.

3. GitHub Flow

   • Simple model: the main branch main is always ready for deployment.
   • For each feature, a branch is created, and after completion — a pull request and merge into main.
   • No separate branches for releases or hotfixes.

4. GitLab Flow

   • Combines ideas of GitFlow and GitHub Flow.
   • Uses environment branches (e.g., production, staging) and feature branches.

The choice of strategy depends on the team size, release frequency, and stability requirements. For example, for large projects with a long cycle, GitFlow is better; for startups and rapid iterations — trunk-based or GitHub Flow.
