Go Diff Checker
Paste two versions of Go code to compare additions, removals and edited lines with Go syntax highlighting. The diff runs locally in your browser.
Texte original
Texte modifié
Go syntax locked
This page automatically highlights Go tokens, so you do not need to pick a language before comparing files.
Private local compare
The diff runs in your browser. Source code, API payloads and configuration files are not uploaded to a server.
Split or unified review
Use split view for side-by-side review, unified view for compact patches, and hide unchanged lines for large files.
Compare Go files online
This Go diff checker is built for developers who need a fast, private way to compare code and configuration changes. Paste two versions, run the comparison, and review additions, removals and inline edits with Go syntax highlighting already enabled.
Paste or upload the original Go file on the left.
Paste or upload the changed Go file on the right.
Compare the result in split or unified view, then hide unchanged lines when you only need the edited regions.
Private browser-based Go comparison
The diff runs locally in your browser, which keeps source code, API responses, secrets and configuration files on your device. One recent session may be stored in your browser storage for restore, and you can clear it from the tool at any time.
Common Go diff workflows
Review generated Go code against edited output.
Check package imports and error-handling edits.
Go syntax highlighting
Highlighting is locked to Go on this page, so the language selector stays out of the way. The parser focuses on tokens such as packages, structs, interfaces, goroutines while the diff engine highlights the actual text changes.

Go diff checker FAQ
What is a Go diff checker?
A Go diff checker compares two versions of Go content and highlights added, removed and edited lines. This page locks syntax highlighting to Go, so language tokens are easier to scan while reviewing changes.
Does this Go diff tool upload my code?
No. The comparison runs in your browser. Your Go files are not uploaded to a server when you click Compare.
Which Go file types can I compare?
You can paste or upload plain-text files such as .go. Any text file can be compared, but this page highlights Go syntax automatically.
Can I compare large Go files?
Yes. Large comparisons run in a background worker so the browser stays responsive. Very large files may still take a few seconds on your device.
