About Code Compare

Free, private text and code comparison

Code Compare shows exactly what changed between two versions of a text or piece of code. Paste the original on the left and the modified version on the right, and every added, removed and changed line is highlighted.

• Side-by-side comparison with syntax colouring for Apex, JavaScript, TypeScript, JSON, HTML, CSS, XML, SQL, Java and plain text.
• Open files from your computer, swap the two sides, and see a summary of how many lines changed.
• Runs entirely in your browser. Your code is not uploaded or stored to our server. See the Privacy Policy.
