rebase vs mergelinear historymerge commitgit rebaseintegration strategy

Problem

Teams use merge and rebase interchangeably without understanding the tradeoffs, resulting in messy history or unexpected SHA changes that break collaborators' branches.

Solution

Merge preserves history as it happened — use for integrating shared/public branches:
git checkout main && git merge feature/my-feature

Rebase rewrites history for a linear timeline — use for local cleanup before merging:
git checkout feature/my-feature && git rebase main

Golden rule: never rebase commits that exist on a remote shared branch. Only rebase your local unshared work.

Why

Merge creates a new merge commit tying two histories together. Rebase replays your commits on top of another branch, rewriting their SHAs. Rebasing shared commits causes divergence for everyone who has the old SHAs.

Gotchas

After rebasing a feature branch, you must force-push it — use --force-with-lease
git pull --rebase avoids merge commits when updating from remote — many teams prefer this for pull operations
Merge is safer in open-source contexts where you don't control other contributors' workflows

Code Snippets

Merge vs rebase patterns

# Merge: preserves branch topology, creates merge commit
git checkout main
git merge feature/my-feature

# Rebase: linear history, replays commits on top of main
git checkout feature/my-feature
git rebase main
# Then fast-forward merge
git checkout main
git merge feature/my-feature

# Pull with rebase (avoid merge commits on pull)
git pull --rebase origin main

Context

Deciding how to integrate a feature branch back into main or keep it up to date
