Shopify Canvas: Build Custom Stores with Sidekick in Real Time

Shopify merchants can now design and customize their entire store visually without writing code or navigating complex settings panels. Canvas, rolling out over the coming days, displays every page side-by-side so you can see the store as a whole, then zoom into any detail. Changes made by Sidekick appear in real time, letting you iterate quickly through chat rather than switching between admin screens.

Sidekick made more than 25 million edits to themes in the first half of 2026, according to Shopify. Because it now works directly on theme files and can navigate templates, sections, and design logic, it can handle tasks from small section tweaks to full redesigns while you stay in the same workspace.

What Canvas Changes About Store Design

Canvas turns your online store into a single workspace. For the first time, you can see every page laid out together, pan across them to understand how the store feels as a whole, and zoom in to work on details. You're not editing a static preview; Canvas renders the real code behind your store with full interactivity and animation.

You can still click on elements to make changes directly, or you can work with Sidekick through chat instead. As Sidekick makes changes, those changes land in Canvas in real time so you can see how they feel in the context of your entire store. Sidekick takes screenshots to inspect its own work, and because both you and Sidekick see the same result simultaneously, you can explore ideas and iterate quickly.

Theme architecture has been simplified to make structure, logic, and design easier for Sidekick to understand and change. Sidekick validates its code and reviews screenshots to refine its work before handing the result back to you.

Who This Helps and What It Replaces

Bespoke store design historically meant writing code yourself, paying a developer, or navigating an unwieldy settings panel. Canvas gives you a third path: conversational design with an agent that knows commerce patterns and Shopify theme architecture.

Shopify's announcement notes that Canvas is not replacing the existing editor yet, and that gaps remain. The rollout is gradual, and Shopify describes this as early work they expect to change quickly. If you need a feature that's only in the existing editor, you'll still use that workflow for now.

The tool is designed for entrepreneurs with a vision but no code experience, as well as merchants who know how to code but want to move faster. Ben Sehl, Shopify's director of product and co-founder of Kotn, said it took him two weeks to build a rough store 12 years ago even though he knew how to code. With Canvas, an entrepreneur can build a fully custom store in 20 minutes, according to Shopify.

Possible Workflows for Product and Campaign Changes

Canvas could simplify the kinds of design tasks that happen frequently in an active store. For example, you might ask Sidekick to adjust a collection page layout before a seasonal sale, then see the change in context with your homepage and product detail pages. If the new layout doesn't match the rest of the store, you can refine it immediately rather than publishing, reviewing, and rolling back.

Another possible use: updating a product detail template to add a size guide or highlight a new feature. Instead of hunting through settings or editing Liquid, you describe the change in chat and watch it land on the page. You can preview how the new section looks with different products and screen sizes before committing the change.

Campaign-specific landing pages are another candidate. If you're running a promotion tied to an email send or ad buy, you could work with Sidekick to spin up a custom page that matches the campaign creative, see it alongside your checkout and cart pages to ensure the flow feels cohesive, and iterate on messaging or layout until it's ready.

These workflows depend on suitable theme architecture, data access, and permissions. Canvas operates on the theme layer, so integration with inventory, orders, or customer data would still rely on apps and the underlying Shopify platform.

How Sidekick Learns Design Preferences

As you work with Sidekick in Canvas, it asks questions, proposes approaches, and takes feedback along the way. It remembers earlier design decisions and carries them into new work, so you spend the conversation making new decisions rather than restating old ones.

Austin Knight, Shopify's design director, explained that every theme has a unique design contract and a curated set of patterns to draw from. Sidekick is trained on what Shopify calls a mountain of opinionated eval data so it brings tasteful, distinct design directions that become a springboard for your own creativity. Whether you arrive with a vague sense of how the store should feel or a pixel-perfect mockup, Sidekick gives you something concrete to react to.

This feedback loop is similar to how Kolton users iterate on customer support and sales workflows. Kolton answers questions using connected Shopify catalog, stock, and order information, and learns from corrections when a merchant approves or edits a draft reply. Canvas demonstrates the same pattern applied to store design: real-time collaboration through chat, with changes visible immediately and context carried forward.

What Canvas Doesn't Cover Yet

The supplied documentation does not establish whether Canvas integrates with post-purchase flows, backend automation, or third-party apps beyond the theme layer. If your workflow requires editing checkout extensions, order processing rules, or email templates, those tools remain separate.

Canvas also doesn't replace the existing Shopify editor yet. Shopify describes the launch as early and notes that things will change quickly. If a feature or workflow you rely on isn't available in Canvas, you'll continue using the existing editor for that task.

Access is gradual. Shopify says Canvas is rolling out over the coming days but does not detail eligibility criteria or regional phasing. Merchants interested in trying it can check Shopify's official Canvas page for availability updates.
