This guide tells you which browsers and devices the Composerie customizer runs on. It is for any merchant whose shopper reports a broken or missing customizer, and who wants to rule out the browser before digging deeper. The short version: a current browser on almost any device works fine.
Supported browsers
Use a current version of Chrome, Safari, Firefox, or Edge. Those four cover almost every shopper, and Composerie is built and tested against their recent releases.
The customizer is not a plain web page. It uses modern browser features called Web Components and Shadow DOM, and it draws every design on a live canvas inside the page. Those features need an up-to-date browser. A very old browser cannot run the canvas, so the customizer can look broken, fail to load, or freeze.
If a shopper hits a problem, the first fix is the browser. Ask them to update to the latest version, or open the product in one of the four supported browsers instead. That single step clears most reports that look like a bug.

Phones and tablets
The customizer works on phones and tablets, and it supports touch editing. A shopper can tap to select, drag to move, and pinch the same way they would in any mobile app. There is no separate mobile version to switch on. The same customizer adapts to the screen.
Appearance follows the device. The customizer is set to detect the store’s light or dark preference automatically, so it matches the phone or tablet without any setting from you.
One detail worth knowing: the storefront-fit layout tools (the toggles that widen the customizer column on a tight theme) apply on desktop only. Mobile is left untouched, because phone layouts already give the customizer the full width it needs.

Frequently asked questions
Which browsers do you support?
A current version of Chrome, Safari, Firefox, or Edge. Keep the browser updated and the customizer runs fine.
The customizer looks broken in my browser. What do I do?
Update to the latest version of your browser, or open the product in a different one. A very old browser cannot run the canvas, which makes the customizer look broken.
Does it work on phones?
Yes. The customizer runs on phones and tablets with touch editing, and it follows your device's light or dark setting automatically.
If a shopper has a current browser and the customizer still misbehaves, the issue is probably elsewhere. Read the customizer is not appearing or performance and slow loading, and contact support if you are still stuck.
