Squash Vs Merge Compared

When working with Git, deciding whether to squash or merge is like choosing between one-pager summary of the progress. Both approaches have pros and cons, and the best choice depends on what matters most for your project and team.

Let’s break this down into digestible comparison!

History Management and Cleanliness

Parameter	Git Squash	Git Merge	Winner
History Management	Streamlined history, consolidating multiple commits into one. Easy to read but loses granular details.	Preserves complete history, which is great for an audit trail but can get messy.	Merge
Cleanliness	Creates a super clean, single-commit history that’s easy to scan.	Shows the full development story, but might be too verbose.	Squash

Tracking Changes and Debugging

Parameter	Git Squash	Git Merge	Winner
Diff Tracking	Easier to track overall changes, but lacks granular details.	Detailed change tracking for each commit, though it can get overwhelming.	Merge
Blame/Find Who Did What	Harder to trace individual contributions after squashing.	`git blame` works as expected, attributing each line to an author.	Merge
Context (Commit Messages)	One commit message summarizes everything, which can miss the small but important details.	Each commit keeps its message, preserving context for every change.	Merge

Collaboration and Long-Running Branches

Parameter	Git Squash	Git Merge	Winner
Collaboration	Combines everyone’s work into a single commit, making integration easier but hiding individual efforts.	Keeps each developer’s commits intact, making it clear who contributed what.	Merge
Long-Running Feature Branches	Squashing reduces clutter by combining everything at the end.	Merging keeps the full history, which is helpful for long-running features.	Merge

Handling Mistakes and CI/CD Pipelines

Parameter	Git Squash	Git Merge	Winner
Revert	Easy to revert a single commit, but partial reverts aren’t possible.	Can revert individual commits, though complex changes might be tricky.	Merge
Conflict Resolution	Fewer conflicts since you squash everything at once, but fixing them might be harder.	Conflicts appear incrementally and can be handled step by step.	Merge
Continuous Integration (CI) Efficiency	Fewer commits mean faster builds, but debugging failures is tougher.	More commits could slow down CI, but make it easier to spot problems.	Squash

So, Which One Should You Choose?

Honestly, it depends on your goals. If you want a clean history and don’t need every intermediate step, squashing is great. On the other hand, if you value detailed traceability and teamwork visibility, merging is the way to go.

For my personal practice, I use squash rarely! A good compromise? Use squash for small features or WIP branches, and merge for major features or shared branches. You get a balance of simplicity with detail — and keep everyone happy.
