ThemeWatch: Compare Theme Code

See exactly what changed in your theme code - no technical or development knowledge required.

Finally understand what's happening with your store's theme code without being a developer. Compare any two themes instantly and see exactly what's different between them - highlighted in a way that makes sense even if you've never seen code before. Perfect for comparing your live theme with a backup before publishing changes, seeing what your developer actually changed (and making sure nothing extra was modified), and checking differences between theme versions before updating.

• Side-by-side comparison of any two themes
• Line-by-line highlighting of all changes
• File-by-file breakdown showing which templates were modified
• Works instantly with all Shopify themes
• No code modifications - ThemeWatch is read-only for safety
