Git Rebase: Should You Rewrite Your Commit History?

Lately, I have implemented many features in my pet project and realised that none of the created branches were merged with the master code. And, I wanted to have a clean update. I was thinking that Git rebase is a perfect and safest solution since I am working on this project alone.

But then I stopped and asked myself: “Is it really safe? Should I even be doing this?”

If you’ve ever wondered the same thing, this post is for you. I’ll explain what Git rebase actually does, when it’s brilliant, and when it can cause absolute chaos. No panic, please. We’ll figure this out together.

TL;DR

  • Use rebase for a clean, linear history (solo work).
  • Use merge for shared branches (don’t rewrite history).
  • Always test and use --force-with-lease when pushing rebased code.
  • git reflog can save your day.

Note: In many newer Git repositories, the default branch is called main instead of master. The same logic applies — swap the name accordingly. I use master though :)

What Is Git Rebase?

Git rebase is a history-rewriting command that replays a branch’s commits on top of another branch’s latest tip, producing a linear commit log instead of a merge commit.

Here’s what actually happens: Git takes your feature branch commits, temporarily removes them, updates your branch to match the latest master, and then replays your commits one by one on top.

The result: a clean, linear history without messy merge commits cluttering your timeline.
