Theme Companion

Theme Companion helps you update your Shopify theme to new versions while keeping all your customizations intact. When you or a developer make code changes to your theme, regular theme updates often leave those edits behind. This app automatically carries your customizations forward into the latest version, so you don't have to move them manually. You can review any conflicting code changes and decide what to keep. The app lets you preview the updated theme on a draft copy before publishing it live, reducing risk. Beyond theme updates, you can add ready-made sections that work with the theme editor and install custom fonts or Google Fonts to match your brand. Works with supported themes only.
