Theme updates don't have to cost you customizations

If you, a developer, or an app has edited your theme's code, a theme update can leave those edits behind. Theme Companion makes sure nothing is lost silently: every customization the update touches is shown to you as a change to review — keep yours, take the new version, or merge both. Your live theme stays untouched until you finish, and you can preview everything on a draft theme first.

Theme Updates

Update your theme without losing your customizations

Move to the latest theme version and bring your edits with you. Where your code and the new version touch the same lines, you decide what to keep — and you check everything on a draft before it goes live.
