Is my code or sensitive data uploaded to any server?

No. Git Diff Checker runs 100% locally in your web browser. None of your source code, text snippets, or files are sent over the network or stored on any server.

What is the difference between Split View and Unified View?

Split View presents original and modified files side-by-side with synchronized scrolling. Unified View displays changes in a single column with '+' (additions) and '-' (deletions), matching the standard git diff command-line output.

Which programming languages are supported?

Git Diff Checker supports syntax highlighting for TypeScript, JavaScript, Python, JSON, HTML, CSS, Go, Rust, Java, C++, C#, PHP, Ruby, SQL, YAML, Markdown, Shell, and Plain Text.

Can I export standard Git patches?

Yes. You can copy the unified Git diff patch to your clipboard or download a .patch file that can be applied directly using 'git apply' in your terminal.

Does Git Diff Checker support word-level and character-level diffs?

Yes. You can toggle between Word granularity, Character granularity, and Line-by-line granularity to pinpoint the exact tokens or characters that changed.
