Visual Code Diff & Merge Tool

How do I compare two code files online to find what changed?

Paste your original code in the left panel and the modified version in the right panel — KuberAgent Diff Checker instantly highlights every addition in green and every deletion in red, line by line, so you can spot exactly what changed without reading both files manually.

Can I use this diff checker to resolve Git merge conflicts?

Yes — paste the original version and the conflicting modified version side by side, inspect every changed line, then copy the merged result you want to keep. It gives you a clean visual comparison without needing terminal commands.

Is my code safe when using this diff checker online?

Yes — all comparison happens entirely inside your browser. Your code is never uploaded to any external server, making it safe to paste proprietary source code, API keys, environment variables, or confidential configuration files.

What types of files and languages can I compare with this tool?

You can compare any plain text content — JavaScript, Python, Java, TypeScript, C++, HTML, CSS, JSON, YAML, XML, SQL, shell scripts, .env files, config files, and plain text documents. Any text-based file works.

How is this diff checker different from running git diff in the terminal?

git diff requires a Git repository and terminal access. KuberAgent Diff Checker works directly in your browser — paste any two text snippets without needing a repo, Git installed, or command-line knowledge. Ideal for quick one-off comparisons.

Can I compare two JSON files to find differences in structure or values?

Yes — paste both JSON files and the diff checker highlights every changed key, value, or structural difference line by line. For large or deeply nested JSON, it's faster than manually reading both files.

How do I ignore whitespace or indentation differences when comparing code?

The tool focuses on meaningful content differences — if your files differ only in spacing or indentation (like a reformatted file), you can identify those quickly and focus only on actual logic changes.

Can I compare two versions of a config file like .env or nginx.conf?

Yes — this is one of the most common use cases. Paste your local and production config files side by side to instantly spot mismatched environment variables, changed values, or missing keys that might be causing deployment issues.

How do I compare two contract or document drafts for changes?

Paste the original draft in the left panel and the revised version in the right panel — every added sentence appears in green and every removed sentence in red, so legal teams and writers can track exactly what was changed between document versions.

Is there a file size or line limit for comparing text with this tool?

Since all processing happens in your browser, performance depends on your device. Most standard code files and documents compare smoothly — for extremely large files exceeding thousands of lines, a terminal tool like git diff or diff command is more suitable.
