Appscodes Simple browser tools for code review and cleanup
Code comparison tool

Compare codes side by side

Paste an original code block and a changed code block, then review the differences in a clean side by side layout. The tool highlights modified rows, added rows, deleted rows, and inline changes so you can inspect updates faster.

This browser based code diff viewer is useful when reviewing snippets, plugin updates, configuration changes, scripts, HTML, CSS, JavaScript, PHP, C#, SQL, Python, and other text based files. Your pasted code is processed locally by JavaScript in your browser.

How the code comparison tool works

Appscodes compares the two pasted inputs line by line, creates difference blocks, and makes the review easier by grouping consecutive changes. Instead of showing every changed line as a separate navigation item, the difference menu points to the first occurrence of each changed block. This makes the result easier to scan when a function, class, or configuration section was edited.

The tool can ignore whitespace, ignore letter case, or hide unchanged lines. These options are useful when you want to focus on meaningful code changes instead of formatting updates. You can also copy or download a simple report for documentation, review notes, or team communication.

Because the comparison runs in the browser, the code you paste is not uploaded for comparison processing. This makes the page practical for quick reviews of scripts, markup, configuration files, and small or medium code snippets.
