ThemeMerge

ThemeMerge is presented as a workflow tool for Shopify merchants who are redesigning a theme copy while preserving changes made to the live theme. It compares the working copy and live theme against a recorded baseline, then merges JSON theme editor data key by key and merges Liquid, CSS, and JavaScript line by line so merchants can resolve remaining conflicts before downloading and uploading the merged theme. The app emphasizes that the live theme is never modified, which should reduce the risk of losing important edits during publishing. There are not enough reviews to analyze right now.
