Your theme editor shows you one page at a time. Canvas shows you all of them.
On October 1, Shopify launched Canvas, a new way to design your online store. Every page sits side by side in one infinite workspace. You pan across the whole store, zoom in on a detail, and change it on the spot. Or you tell Sidekick, Shopify's AI assistant, what you want and watch it build.
It's an impressive release. It's also early. And there's one limitation that matters a lot if you sell in more than one country.
What Shopify Canvas actually does
Think of it as a moodboard that happens to be your real store.
The current theme editor works page by page. You open the product template, adjust a section, save, then go and check the homepage to see if it still feels right. Canvas removes that back and forth. Homepage, collection, product page and cart all sit next to each other, so you judge the store as a whole.
In Canvas you can:
- See every page at once. Pan across the store, then zoom in on any detail.
- Edit directly or by chat. Click an element to change it yourself, or describe the change to Sidekick.
- Watch changes land in real time. From one section to a full redesign.
- Preview the real store. Canvas renders the actual theme code, with working interactions, animations, different products and collections, and mobile or desktop sizes. It's not a static mockup.
Sidekick writes code now
This is the part worth pausing on.
In Canvas, Sidekick doesn't just move sliders in a settings panel. According to Shopify, it works directly in your theme's files and writes custom theme code. It asks questions, suggests design directions, remembers your earlier decisions, and checks its own work with screenshots before handing it back.
For merchants, that means changes that used to need a developer can now start as a sentence. "Make the product page feel calmer." "Move reviews above the fold." "Try a bolder collection grid."
That's a real shift in who can shape a store, and how fast.
What Canvas can't do yet
Shopify is open about this. At launch, Canvas does not support:
- Shopify Markets. You can't keep market-specific theme variations in Canvas.
- Translations. Theme content has to be translated with Translate & Adapt, outside Canvas.
- App blocks and app embeds. Reviews, loyalty, search and other apps that plug into your theme can't be added or configured. Shopify staff have said app support is coming within weeks.
- Third-party themes. Only Shopify's own themes and custom themes work. Themes bought from the Shopify Theme Store don't.
- Rollouts. You can't use Shopify's scheduled theme rollouts to edit a Canvas theme.
Two more things to know. Canvas is desktop only. And it's rolling out gradually, so you might not have it yet.
The detail most people will miss
A theme edited in Canvas no longer receives theme updates.
Once Sidekick starts writing code into a theme, that theme is yours. It no longer gets the bug fixes, performance improvements and new features the theme developer ships. That's fine if you own and maintain your code. It's a problem if you were counting on those updates arriving automatically.
So treat a Canvas theme like a custom build. Someone needs to own it.
Who should use Shopify Canvas today
Try it now if you run a single-market store on a Shopify theme like Dawn or Horizon, with few theme apps. Canvas can save you real time.
Experiment, but don't go live, if you sell across the Nordics or the EU with Markets and translations, or your store depends on app blocks. That's most of the established brands we work with. Without Markets and app support, a Canvas theme can't replace your live theme without breaking something your customers rely on.
The good news is that experimenting costs nothing. Go to Online Store > Themes, duplicate your theme into Canvas, and let Sidekick try a few ideas. Your original theme stays in the current editor, untouched.
It's a fast and honest way to explore a redesign, and a useful brief to bring to your developers when it's time to build it properly.
Our take
Canvas points to where Shopify store design is heading. Visual, conversational, and much closer to the real thing than a static design file. We expect it to become the default editor once Shopify adds app support.
But a store that sells in eight markets and four languages needs more than a good-looking homepage. It needs code someone understands, apps that work and translations that hold up at checkout. Canvas will get there. It isn't there yet.
If you've tried Canvas and want a second opinion on what Sidekick built, send it our way. We'll tell you what we'd keep, what we'd rebuild, and whether it's ready for your live store. No pitch. Just a conversation.
