Shopify launched Canvas, a visual workspace where merchants build a store by chatting with the Sidekick AI agent

Any merchant with a Shopify store can soon tell Sidekick, Shopify's AI agent, to redesign the home page while watching every other page change in the same workspace. Shopify announced Canvas on 1 October 2026 and said it is rolling out to merchants over the coming days.

Canvas is a design surface where the whole store sits side by side on one zoomable canvas. A merchant pans across the home page, product pages and checkout to see how the store feels together, then zooms in and asks Sidekick in a chat to adjust an element. Sidekick writes the change to the theme files, and the canvas re-renders the real code so the merchant sees the result with full interactivity and animation across different screen sizes.

What is new under the surface

Sidekick itself has been writing Shopify code for some time. By Shopify's own count, it has made more than twenty-five million edits to merchant themes in the first half of 2026, mostly inside the existing editor and settings panel. Canvas is the product that pulls that work into a single whole-store workspace rather than a per-section tool.

To make that possible, Shopify changed two things. Sidekick now writes directly to a theme's files instead of flipping settings, and Shopify simplified theme architecture so the store's structure, logic and design are easier for the agent to read and change. As Sidekick builds, it validates its code and inspects screenshots of the canvas to check how a change landed, then refines before handing the result back.

Austin Knight, design director at Shopify, told the company's newsroom that getting Sidekick to write code was easy but guiding it toward good design decisions took most of the effort. Each theme carries a curated set of patterns plus what Knight calls a mountain of opinionated eval data, and that is what lets Sidekick propose distinct design directions rather than a generic layout.

What is not in the launch

Canvas is desktop only on day one. Shopify's own announcement lists several surfaces that are not included yet: third-party themes, app blocks and extensions, markets, translations, rollouts and theme updates. The existing theme editor is still there, and Ben Sehl at Shopify said in the launch post that Canvas is not replacing it. The company told TechCrunch it plans to add the missing pieces over time.

The reader for a Shopify consultancy or agency is the person whose week shifts the most. A store build that used to be about writing Liquid templates becomes a conversation about tone, hierarchy, imagery and layout, with the review happening on a canvas that already shows what the final site will look like. The agent still has gaps, and the first few passes with a client are likely to produce something to react to rather than something to ship. Shopify's own framing says exactly that: Canvas gives a merchant something concrete to work from, and the design is refined with Sidekick from there.
