Deciding When to Use GitKraken's Visual Merge Tool

Decision: resolve merge conflicts visually or from the command line

You are mid-merge and Git reports a conflict in src/config.js. The same line changed on two branches, so Git cannot combine them automatically. You must decide whether to open GitKraken's Merge Tool or drop to the terminal and edit conflict markers by hand.

Useful takeaway: choose GitKraken's visual Merge Tool when you need to pick specific lines or blocks from both sides of a conflict. Fall back to the command line for very large conflicts, when GitKraken cannot launch its merge view, or when your system Git version conflicts with GitKraken's expectations.

Constraints and assumptions

• GitKraken desktop is installed and connected to a local Git repository.
• The system has a working Git installation; GitKraken delegates index operations to it.
• You have write access to the repository and can create branches and commits.
• This guide covers standard text-file merge conflicts, not encrypted files or binary assets.

Terms: a merge conflict occurs when Git cannot automatically combine changes from two branches. The index, also called the staging area, holds changes prepared for the next commit. Staging a file marks it as resolved and ready to commit.

Supported options compared

Option	Best for	Primary trade-off
GitKraken Merge Tool	Selecting exact lines or blocks from local and remote versions	Relies on system Git; UI may lag with thousands of conflicting changes
Command line (manual marker editing)	Large conflicts, headless servers, scripted workflows	Manual editing of conflict markers is error-prone; no automatic staging

Trade-offs

GitKraken Merge Tool

The Merge Tool shows a side-by-side comparison: the local change, the remote change, and the resulting merge output. Checkbox-style controls let you accept a block from either side or keep both. Once you mark the conflict resolved, GitKraken stages the file in the index automatically.

The risk is visual oversight: it is easy to discard a necessary line while clicking through blocks. Very large conflicts can also make the interface sluggish compared with text-based tools. Because GitKraken calls the system Git binary, a version mismatch between GitKraken and installed Git can occasionally produce index errors.

Command line

Editing conflict markers directly works in any environment and scales to large files. You control every character, but you must remove the markers yourself and remember to run git add to stage the resolved file. A missed marker can break the build or introduce a failed commit.

Concrete validation: resolve a conflict in GitKraken

This example creates a conflict intentionally, then resolves it through GitKraken's Merge Tool. Run terminal commands in your repository directory with write permissions.

1. Create two branches that touch the same line

# Terminal: local repository directory
git checkout -b feature-branch main
# Edit src/config.js, changing line 10 to: timeout = 30
git add src/config.js
git commit -m "Set timeout to 30 on feature branch"

git checkout main
# Edit src/config.js, changing line 10 to: timeout = 60
git add src/config.js
git commit -m "Set timeout to 60 on main"

git merge feature-branch

Expected result: Git reports a merge conflict and stops before committing.

2. Open the GitKraken Merge Tool

In GitKraken, the merge view opens automatically or from the central commit panel. Locate src/config.js in the conflicted files list and open it. The tool displays the local version, the remote version, and the merge result.

3. Select the correct block

Use the checkboxes to choose which version of line 10 to keep, or edit the result pane directly if you need a combined value such as timeout = 45. Review the full result pane before proceeding.

4. Mark resolved and verify

Click the resolve button. GitKraken stages the file. In a terminal, confirm the result:

# Terminal: same repository directory
git status
git diff --cached -- src/config.js
grep -n '<<<<<<<' src/config.js || echo "No conflict markers found"

Expected checks: git status lists src/config.js as staged; git diff --cached shows your chosen content; the grep command returns no markers.

Risks

• Selecting the wrong block discards code silently. Review the result pane before resolving.
• If GitKraken reports an index error, your system Git version may not match what GitKraken expects. Update Git or resolve via command line.
• Large conflicts with thousands of changes may load slowly in the GUI.

Rollback

Resolving a conflict changes the working tree and index, so rollback is available at two points:

• Before marking the file resolved: run git merge --abort in the terminal to return to the pre-merge state.
• After resolving but before committing: run git reset --mixed HEAD to unstage, or restore the file from the pre-merge commit and start over.

Limitations

• Visual resolution does not replace logical review. A block can look correct in the diff but break program behavior.
• GitKraken's Merge Tool requires a graphical desktop session; it is not available on headless servers.
• Binary files cannot be resolved line-by-line in the Merge Tool.

Check the result

The practical verification is to confirm no conflict markers remain and the file is staged:

git status --short src/config.js
grep -rn '<<<<<<<\|=======\|>>>>>>>' src/ || echo "Clean"

If the file appears under "Changes to be committed" and no markers exist, the conflict is resolved and ready for commit.
