ThemeMerge PRO
Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureThemeGuard helps merchants manage Shopify theme changes with greater visibility and control. It lets you compare theme versions, take and manage snapshots, and track modifications before publishing. You can assign approval statuses, schedule automated backups, and restore previous versions when needed.
When you build a redesign on a copy of your theme, edits made to the live theme in the meantime are lost on publish. ThemeMerge compares both themes against a baseline you record when the copy is made, so it knows what each side changed. Theme editor JSON merges key by key, keeping sections added on either side. Liquid, CSS and JavaScript merge line by line.
- Compare theme versions and review code differences
- Take and manage snapshots of any theme
- Schedule automated backups for published themes
- Assign approval statuses before releasing updates
- Three-way compare of live theme and working copy against a recorded baseline
- Theme editor JSON merged key by key, so sections added on both sides are kept
- Section and block order merged so both sides' additions stay in place
- Resolve conflicts one at a time, per file, or by editing the result directly
