What is rebase in GitHub?
Rebase in GitHub usually means Git rebase: moving your branch’s commits onto a new base commit so the history looks linear and tidy. GitHub’s own docs describe it as changing a series of commits, with options like reorder, edit, or squash, while Git internally creates new commits during the process.
[1][7]Quick Scoop
- What it
does: It reapplies your commits on top of another branch, like
updating your feature branch to start from the latest
main. [3][1] - Why people use it: It keeps history cleaner and easier to read because it avoids an extra merge commit. [5][3]
- Important catch: Rebase rewrites history, so the commits after rebasing are new commits, even if the changes look the same. [1][5]
Simple example
- You create a
feature branch from
main. - Other people add new commits
to
main. - You rebase your feature branch onto the updated
main. - Your work is replayed on top of the newest commits, so the branch history looks straight instead of split. [2][7]
Rebase vs merge
| Aspect | Rebase | Merge |
|---|---|---|
| History | Linear and cleaner | [3][5]Keeps branch structure with a merge commit | [2][5]
| Commits | Creates new commit versions | [1][3]Usually preserves original commits | [2]
| Best for | Updating feature branches and cleaning up local work | [7][3]Combining branches without rewriting history | [5][2]
Why it matters
Rebase is great when you want a clean project history, especially before opening a pull request. But because it rewrites commits, it is safer to use on your own local branch than on shared public branches.
