Code merging enables developers to integrate code after changes as well as bug fixes. To regain their confidence, integration efforts should be smooth and complete that is; without any errors. The modern merge solution has made it possible for the merging tools to report back to a developer(s) in case there have been conflicts preventing tools from merging automatically.
With modern solutions, developers have gained confidence when they were using traditional development methods to merge large blocks of code. These new solutions are more robust. DevOps are using Agile methodologies to help developers keep small changes subsequently reducing the need for merging large chunks of code.
Teams can use code merge tools to identify conflicts though developers are still required to engage in open communication with other developers when they are working on the same code. A great place for developers can discuss any arising conflicts as well as other issues through Stand-up meetings, it is a great place for that forum discussion.

Available tools for code merging
Here are some tools to consider when choosing a code merge tool.
1. Git
Many developers prefer using Git because of its effective branching functionality in the programming industry. it is simple and easy to use. It is suitable for experienced developers.
Key features:
- Branching functionality
- Distributed architecture/built-in backup system
- Free, open source
2. KDiff3
KDiff3 is a comparison program set aside with a merge function. It enables developers to make changes in the output window directly though currently, it hasn’t been updated for a while but perfectly works well with the current functions it supports. It is suitable for both beginners and experienced developers.
Key features:
- A 3-way merge for automated merging
- An alternative option of manual resolve conflicts in case the 3-way merge fails
- Free, open source
3. Beyond Compare
When it comes to comparing and merging, Beyond Compare is a higher-end product, it’s a pro-edition; it supports various programming languages and has the ability to add more languages from online sources. You can use this tool to read PDF files as well as other binary files for comparison, unlike most other merge tools that don’t support it. It is suitable for development teams who have a decent development budget and are in need of the robust functionality found in the Beyond Compare merge tool.
Key features:
- Supports 3-way merge
- Supports regular expression
- Syntax highlighting ability
- Converts binary files to text
- Compare registry hives.
- Customized alignment.
- Paid
4. DiffMerge
DiffMerge is simple and easy to install and use. This tool can be amalgamated as Git’s merge tool. It has a graphical interface and an intuitive tool for developers to directly make changes in the tool.
Key features:
- Software’s ability to compare any two files/folders
- Supports 3-ways merging though conflicts are resolved by developers
- Supports directory comparisons
- $39 one-time fee
5. Semantic Merge
Semantic merge operates quite differently from other code merge tools. it has a parser that enables it to resolve conflicts; it reports at the function level instead of changes in position making it an easy task for developers when refactoring. In case the parser fails to determine the code then the tool will automatically revert to a text-based merge tool of the developer’s choice. It is good for Developers who re-factor frequently.
Key features:
- Parser-based comparison
- Supports VBNET, Java, C# AND C/C++
- Allows external parsers’ configuration
- Paid
