The short version
Duplicating a Shopify-developed or custom theme into Canvas costs your live store nothing until you publish: Sidekick redesigns the copy while your original keeps working in the theme editor.
Publishing that copy is the real decision, because a theme edited in Canvas gets no theme updates, its files can't be downloaded, and you can't add or configure app blocks or app embeds or customize it per market in Canvas. As of October 2026, Canvas is in early access for certain stores, on desktop only, on plans that include theme customization, and the Canvas help pages, changelog and news post name no separate price.
The Quick Verdict
Find your situation in the left column. Every row rests on a limit or a mechanism explained further down.
Should you duplicate your theme into Canvas?
| Your situation | Pick | Why |
|---|---|---|
| Your storefront relies on app blocks or app embeds | Keep publishing from the theme editor | You can't add or configure app blocks or app embeds in Canvas |
| You customize the theme per market | Stay in the theme editor for now | You can't customize a theme for different markets in Canvas |
| You sell in several languages | Canvas works; translate outside it | Theme content is translated in Translate & Adapt, with the Default theme content resource, not in Canvas |
| Your theme comes from a third-party Theme Store developer | Canvas isn't available for it | Canvas works only with themes developed by Shopify and with custom themes |
| Your store needs no app blocks, app embeds, per-market customization, theme updates or theme file downloads | Duplicate, redesign, then publish from Canvas | None of the copy's limits touch your store, and the original stays in your theme library as a fallback |
| You want to try a redesign without touching the live store | Duplicate in Canvas as a sandbox | The original stays in your theme library, and you keep editing it in the theme editor |
| You want a fresh design from a description | Click New | The new theme is added unpublished, so customers can't view your changes until you publish that theme |
What Is Shopify Canvas?
Key takeaway
Canvas is where Shopify now lets you design a theme by describing it. Shopify's Help Center puts it plainly: you can use Canvas to create or edit an online store theme, and it displays all your store's templates side by side. You can ask Sidekick to build or change the theme from your description, or edit blocks, settings and text yourself.
Sidekick already worked inside the theme editor before Canvas arrived. Canvas is a second place where it changes a theme, with its own rules for saving and publishing, covered below; how Sidekick behaves in the theme editor is answered in can Sidekick edit your live theme.
You reach Canvas from Online Store > Themes, and there are three ways in:
- New builds a theme from your description. It's added to your theme library as an unpublished theme.
- Duplicate in Canvas, on a supported theme, opens a copy in Canvas. The original stays in your theme library.
- Edit theme, on a theme that shows the Canvas badge, reopens it in Canvas.
Canvas works on themes inside your own Shopify admin. The partner AI tools that generate a storefront for you are a different route, compared in our guide to building a Shopify store with AI.
Canvas in this article is the Shopify product you open from Online Store > Themes. Some writing about the Horizon theme, our own Horizon guide included, uses "canvas editing" for editing content directly on the preview in Horizon's theme editor; that is a theme-editor feature, not this product.
Canva is a separate design company, and the Theme Store's "Canvas Website templates" page is a template collection for canvas store websites, not the product either.
Who Can Use Shopify Canvas Right Now?
Key takeaway
Two gates stand between you and Canvas, and it pays to check them in order. The first is whether your store has Canvas at all. The second is whether it opens on the theme you want to change, from the device and the staff account you are using.
Early Access: Is Canvas in Your Store Yet?
Key takeaway
When we read all four Canvas pages in Shopify's Help Center on October 2, 2026, each one opened with the same Early access note: "Canvas is in early access and is available only to certain stores."
Shopify announced Canvas in its changelog on October 1, 2026, saying it "is rolling out to existing stores over the coming days", and the news post that day said the same of merchants. That date starts a gradual rollout; it isn't the day your store gets access.
The announcement is also clear that Canvas sits beside the theme editor rather than replacing it. Ben Sehl, Shopify's Director of Product, put it this way:
We’re early here and Canvas is not replacing the existing editor yet.
The same post says "there are gaps we still need to close", so read every limit in this article as the state of October 2026, not a permanent design. To see whether your store has Canvas, open Online Store > Themes: the Help Center's entry points are a New button and a Duplicate in Canvas option on a supported theme.
No Canvas page, changelog entry or news post we read on October 2, 2026 names a separate price for Canvas (see What we looked for and did not find, below). What the requirements name instead is a plan that includes theme customization.
What Canvas Needs From Your Device, Plan, Theme and Staff
Key takeaway
Once Canvas is in your store, the Help Center lists four requirements. Each one has a place you can check it and a consequence if you don't meet it.
The four requirements for opening Canvas
| Requirement | Where you check it | If you don't meet it |
|---|---|---|
| A desktop device | The computer or device you edit on | Canvas doesn't open. On a phone, the online store editor with Sidekick is the theme editor, not Canvas. |
| A plan that includes theme customization | Your Shopify plan. Shopify's Starter plan page says "Other themes and customization options aren't available on the Starter plan", though it doesn't mention Canvas. | Canvas isn't available. Move later to a plan without theme customization and you can still view themes edited in Canvas, but you can't edit or publish them. |
| A theme developed by Shopify, or a custom theme | Who developed the theme: theme sources are either Shopify or a third-party developer | Third-party themes aren't supported, so Canvas won't take that theme. |
| The Online store > Themes > Edit code permission | The staff member's permissions | That staff member can't open Canvas. Granting it also lets them modify theme code directly through the code editor. |
Source: Requirements for using Canvas, Shopify Help Center, read October 2, 2026.
If your theme came from a third-party developer on the Theme Store, Canvas won't open it as of October 2026, and Shopify's launch changelog lists those themes first among what Canvas doesn't support "at launch". Sidekick isn't off the table, though: Shopify's Winter '26 Edition says it "can create custom blocks in any theme from the Shopify Theme Store". The Help Center places block generation in the theme editor and says a compatible third-party theme must be purchased first; a free trial version doesn't support it.
Not sure which kind of theme you run? Shopify sorts every theme you can add as developed either by Shopify or by a third-party developer, and our guide to the types of Shopify themes walks through telling them apart.
What Happens When You Duplicate a Theme in Canvas?
Key takeaway
Duplicate in Canvas doesn't convert your theme. It makes a copy, and the copy opens in Canvas; the original stays in your theme library. From then on you can edit the copy only in Canvas, and you can keep editing the original in the theme editor.
That split is the part that is easy to underestimate. Shopify's Help Center flags it with a caution:
The two themes are separate, so changes that you make to one theme aren't added to the other.
So a fix you make on the live original next week won't appear on the Canvas copy, and a section Sidekick builds on the copy won't reach the original. Themes edited in Canvas carry a Canvas badge in your theme library, and Edit theme on one of them reopens it in Canvas.
Duplicating also needs room. Shopify's page on duplicating themes says that with 20 themes already in your admin, you delete one before you can duplicate another, and that page names no plan. Shopify's page on adding themes puts the limit at 20 themes on the Basic, Grow and Advanced plans and 100 on Shopify Plus. The Canvas pages we read on October 2, 2026 don't say whether a Canvas copy counts toward either limit (see What we looked for and did not find, below), so clear a slot if you are close to it.
What Does a Theme Edited in Canvas Give Up?
Key takeaway
The cost of Canvas is paid by the theme, not by the store. The Help Center's considerations page, read on October 2, 2026, lists what changes for any theme you edit in Canvas, whether you duplicated it or built it with New. The table sets each item beside what still works.
What a theme edited in Canvas gives up
| What you'd normally do | On a theme edited in Canvas | What still works |
|---|---|---|
| Install theme updates | Doesn't receive theme updates | The original you duplicated from stays in your theme library, outside Canvas |
| Download the theme files | You can't download its theme files | Back up the original before you duplicate |
| Add or set up app blocks and app embeds | You can't add or configure them in Canvas | Nothing inside Canvas; keep app blocks and embeds on a theme you edit in the theme editor |
| Customize the theme for different markets | You can't customize it per market in Canvas | Nothing inside Canvas as of October 2026 |
| Translate theme content | You can't translate it directly in Canvas | Translate & Adapt, with the Default theme content resource |
| Use the theme in a rollout | You can't edit it through a rollout or open it from one | Add it to a rollout as a replacement for your main theme, and edit it in Canvas |
Source: Considerations for using Canvas, Shopify Help Center, read October 2, 2026. The app-embed note in the third row is explained in App blocks and app embeds, below.
No Theme Updates, No Downloadable Files
Key takeaway
On a theme you edit in the theme editor, an update carries your work forward: Shopify's page on updating themes says customizations made with the theme editor "are copied over and applied to the updated theme". How updates fit into running a Shopify theme day to day is covered in our Horizon theme guide.
A theme edited in Canvas sits outside that process altogether. The requirements page says so in one line:
A theme that you edit in Canvas doesn't receive theme updates.
If you install theme updates as they ship, that habit stops working on the copy. The next line on the same page affects backups: you can't download the theme files for a theme that you edited in Canvas. What a theme download contains and leaves out is in our answer on downloading your Shopify theme code.
Duplicating the live theme and downloading the copy still works for the original, just not for anything you edit in Canvas. Run the manual backup routine on the original before you duplicate it.
Markets, Translations and Rollouts
Key takeaway
You can't customize a theme for different markets in Canvas. If your store shows a different theme setup to different markets, that work can't move to a Canvas theme. Which plans offer per-market theme customization at all is covered in which plans can customize a theme per market.
Translation runs outside Canvas. The Help Center says you can't translate theme content directly in Canvas and points to the Translate & Adapt app; to translate manually there, always select the Default theme content resource. The Translate & Adapt help page repeats that note for any theme edited in Canvas.
Rollouts work in one direction. You can add a theme you edited in Canvas to a rollout as a replacement for your main theme, but you can't use the rollout to edit that theme or open it from there; to edit it, you open it in Canvas. How rollouts work in general is covered in our guide to A/B testing with Shopify rollouts.
Two official sources describe this differently. Shopify's launch changelog, read on October 2, 2026, says that "at launch" Canvas doesn't support "Markets, rollouts, translations, or app blocks and app embeds". The Help Center pages, read the same day, are more specific about two of those: translations go through Translate & Adapt, and a theme edited in Canvas can be a rollout's replacement theme.
Plan with the Help Center version, because it names what you can actually do: translate in Translate & Adapt with the Default theme content resource, and add a Canvas theme to a rollout only as the replacement theme, editing it in Canvas.
App Blocks and App Embeds
Key takeaway
For an established store, this is the line most likely to decide the question: you can't add or configure app blocks or app embeds in Canvas. If an app puts something on your storefront, find out how it does that before you duplicate.
What happens to app blocks and embeds already switched on when you duplicate is a separate question, and the Canvas help pages we read on October 2, 2026 don't answer it (see the box below).
The clearest statement is a Shopify staff post on its developer forum, written to app developers: "If a merchant creates or duplicates a theme in Canvas, your app's blocks and embeds won't be available in that theme for now." The same post says themes edited in Canvas also won't appear when an app lists a store's themes.
That post also says Shopify expects to support theme app extensions before Canvas becomes the default editor, and a Shopify staff reply in the same thread, posted October 1, 2026, says, "We plan to support theme app extensions in Canvas within the next few weeks." Treat both as plans, not something to schedule around: if your storefront depends on an app's widget today, keep publishing a theme you edit in the theme editor.
Where this page says Shopify's Help Center, changelog or news post don't state something, it reads off these sources, checked on October 2, 2026:
- App blocks and app embeds already switched on when you duplicate: the four Canvas pages in Shopify's Help Center, the launch changelog, the Help Center pages on updating and duplicating themes, and the Introducing Canvas news post. Only Shopify's staff post on its developer forum, quoted above, speaks to it.
- Whether a Canvas copy counts toward the 20-theme limit on the duplicating page or the plan-based limit of 20 or 100 themes on the adding-themes page: the four Canvas pages, the Help Center pages on duplicating, adding and downloading themes, and the news post.
- A separate price for Canvas: the four Canvas pages, the launch changelog and the news post.
The absence is the finding. A page Shopify adds later would change it.
How Editing in Canvas Differs
Key takeaway
Working inside Canvas changes two habits: how you add things to a template, and how you take changes back.
Sidekick Does the Structural Work
Key takeaway
Besides the app block and app embed limit covered above, three more editing limits apply in Canvas:
- New blocks come from Sidekick. You can't add a new block to a template manually; ask Sidekick to add it, and describe the content, appearance or layout you want.
- Some older themes lock preview text. On some older themes, you can't edit text directly in the preview; change it in the block's settings instead, or ask Sidekick to change it.
- Metaobject templates aren't in Jump to... You won't find them in that list in Canvas.
Before you publish, review your changes at each preview width. That is the Help Center's own advice for Canvas, and the widths are available in the full-screen view.
Sidekick Clears Undo; Version History Doesn't
Key takeaway
Your changes are saved automatically in Canvas, so there's no save button. That removes the risk of losing work and adds a different one: nothing stands between an experiment and the saved theme.
When Sidekick makes a change, your undo history is cleared, and you can't use Undo to reverse that change or any change you made before it. To reverse it, ask Sidekick to change it back, or restore an earlier version from Version history.
Version history is the safety net. The newest version is marked Current version, and the one you last published is marked Last published. Restoring a version replaces your current version in Canvas, and customers see it only after you publish it.
Publishing From Canvas Without Losing Changes
Key takeaway
Because Canvas saves as you go, Publish doesn't save your work; it makes your changes visible to your customers. The publish button follows the theme: on an unpublished theme it reads Publish, and on your published theme it reads Update.
The published theme is the case that surprises people, because saved edits build up where shoppers can't see them:
Your customers continue to view your store as it was. They can view your change only after you click Update, and then Publish changes.
What a change in Canvas does, theme by theme
| Theme | When you make a change | What customers see | How it goes live |
|---|---|---|---|
| An unpublished theme (Draft theme) | Saved and shown in Canvas | None of the changes: it isn't your published theme | Publish, then Publish changes |
| Your published theme, edited in Canvas (Live theme) | Saved and shown in Canvas | Your store as it was, until you publish the change | Update, then Publish changes |
| The original you duplicated from | Canvas changes never reach it | Unchanged by anything you do in Canvas | Edited and published from the theme editor, outside Canvas |
Source: Creating and customizing themes in Canvas and Using and navigating Canvas, Shopify Help Center, read October 2, 2026. Live theme and Draft theme are the labels Canvas shows when you hover over the theme name.
Before you click Update or Publish:
- Check which theme you are on. Hover over the theme name in Canvas to see whether it is the Live theme or a Draft theme.
- Look at the store as customers do. Your published theme can hold saved changes that aren't live yet, so open your online store in a new browser tab.
- Let Sidekick fix publishing errors. If the theme can't be published, the dialog lists the errors; click Fix with Sidekick to have Sidekick fix them.
With a duplicated theme, the last risk is publishing the wrong one. The Help Center's caution ends: "Before you publish, make sure that you're publishing the theme that has your latest changes." If you kept fixing the original while redesigning the copy, those fixes are not on the copy.
Should You Duplicate Your Theme Into Canvas?
The verdict at the top answers by one signal at a time. This quiz answers by the combination: what you want to change, who built your theme, how much your storefront leans on apps, your languages and markets, and who looks after the code, because a store rarely meets just one of the limits above.
Find your Canvas routeFive questions about your theme, your apps and your markets
Before You Click Duplicate in Canvas
Key takeaway
Steps one to five happen before you click, whichever route the quiz gave you. If you are using the copy as a sandbox, stop after step seven and keep publishing the original. If you are starting with New instead, skip step four and the backup in step five, since there is no original to keep in step.
Before and after Duplicate in CanvasTick each step off as you go from checking the theme to publishing the one with your latest changes.
Before and after Duplicate in Canvas
Tick each step off as you go from checking the theme to publishing the one with your latest changes.
Check that Canvas shows up in your store, then the four requirements: a desktop device, a plan that includes theme customization, a theme developed by Shopify or a custom theme, and the Edit code permission for whoever opens Canvas.
Before you tick this off
- New and Duplicate in Canvas appear under Online Store > Themes (early access, as of October 2026)
- You're working on a desktop device
- Your plan includes theme customization
- The theme was developed by Shopify or is a custom theme, not a third-party Theme Store theme
- The staff member has the Online store > Themes > Edit code permission
Canvas can't add or configure app blocks or app embeds, so know which app features the copy would put at risk.
Before you tick this off
- Every app that adds something to your storefront is on the list
- You know which of those your store can't run without
Translation moves to Translate & Adapt with the Default theme content resource, per-market customization isn't available in Canvas, and Shopify's Help Center lets a rollout use the theme only as a replacement for your main theme (the launch changelog lists rollouts as unsupported at launch).
Before you tick this off
- You know which languages the theme content is translated into
- You know whether any market has its own theme customizations
- Any rollout you plan uses the Canvas theme only as the replacement theme
The copy is edited only in Canvas, the original in the theme editor, and changes never pass between them.
Before you tick this off
- You know which of the two themes you'll publish
- Fixes to the live theme have an owner while the copy is in progress
Shopify's duplicating page makes you delete a theme first once 20 are in your admin and names no plan, while Shopify's page on adding themes allows 20 themes on the Basic, Grow and Advanced plans and 100 on Shopify Plus. The Canvas pages don't say whether a Canvas copy counts, so clear a slot if you're close. You can't download files from a theme edited in Canvas.
Before you tick this off
- You have fewer than 20 themes or one you can delete (Shopify Plus can add up to 100)
- The original is backed up before you duplicate it
Choose Duplicate in Canvas on the theme, then work with Sidekick; a Sidekick change clears Undo, so to reverse that change ask Sidekick to change it back or restore a version from Version history.
Before you tick this off
- The copy shows the Canvas badge in your theme library
- You know where Version history is before Sidekick makes large changes
Review your changes at each preview width, and open your online store in a new browser tab to see what is live.
Before you tick this off
- Every preview width has been reviewed
- You know which saved changes aren't live yet
Click Publish, or Update on your published theme, then Publish changes; if the dialog lists errors, click Fix with Sidekick.
Before you tick this off
- You're publishing the theme that has your latest changes
- The live store, opened in a new tab, shows the change
The Bottom Line
Key takeaway
Canvas lets you redesign a theme by describing it, and duplicating costs your live store nothing until you publish. What it costs is the theme's independence: the copy gets no theme updates, its files can't be downloaded, and in Canvas you can't add or configure app blocks or app embeds or customize it per market. If you are weighing Canvas against hiring a developer or buying a theme, our Shopify development guide routes you to the right option in a minute.
