Frequently Asked Questions

What is the difference between Git, GitHub, and GitLab?▾

Git is the version control system - the software that tracks changes locally. GitHub is a cloud platform for hosting Git repositories with collaboration features (pull requests, issues, Actions CI/CD). GitLab is an alternative to GitHub that adds more built-in DevOps features (container registry, security scanning, review apps) and can be self-hosted. Bitbucket is Atlassian's Git hosting option.

What Git workflow should teams use?▾

GitHub Flow is the simplest effective workflow: main branch is always deployable; feature branches are created, developed, PR'd, and merged. Gitflow adds dedicated release and develop branches - appropriate for versioned software but overkill for continuous deployment apps. Trunk-based development (short-lived branches, deploy frequently) is the pattern at high-velocity teams shipping multiple times per day.

What is a pull request and why is it important?▾

A pull request (PR) is a request to merge code from a feature branch into the main branch - triggering code review, automated testing, and discussion before integration. PRs are the quality gate that prevents untested or unapproved code from reaching production. Well-maintained PR workflows (clear descriptions, small focused changes, prompt reviews) are among the highest-impact practices for software quality.

What is version control and why do I need it?▾

Version control is a system that tracks changes to code over time, letting you see the history of every change, revert to earlier versions, and collaborate with others without overwriting each other's work. You need it for any project beyond the trivial, since it provides a safety net (undo mistakes), collaboration (multiple people on the same codebase), and history (understand how and why code changed). Git is the standard. Even solo developers benefit, since it protects against losing work and makes experimentation safe. It is a foundational, non-negotiable tool in modern software development.

What is the difference between Git and GitHub?▾

Git is the version control system itself, the software that tracks changes and manages history on your machine, created by Linus Torvalds. GitHub is a cloud platform that hosts Git repositories and adds collaboration features on top: pull requests, issue tracking, code review, and project management. Git works without GitHub, but GitHub (and alternatives like GitLab and Bitbucket) make it easier to collaborate, share code, and manage projects online. In short, Git is the tool, and GitHub is a popular hosting and collaboration service built around it, so you use Git while GitHub hosts the result.

Do solo developers need version control?▾

Yes. Even working alone, version control provides a safety net to undo mistakes and revert to working versions, a history of how your code evolved, and the freedom to experiment on branches without fear of breaking things. It also backs up your code when using a hosted platform. The habit of committing work protects against losing progress and makes it easy to track down when a bug was introduced. Solo or team, version control is a fundamental practice that pays off constantly, so adopting Git early is worthwhile regardless of project size.
