Shopify launches Canvas so merchants can redesign whole stores with Sidekick

Shopify said Thursday it is rolling out Canvas, a new design surface where merchants pan across every store page and work with Sidekick — Shopify’s AI agent — to turn chat into live theme-code changes in real time.

Store design used to mean hiring a theme shop or fighting a settings panel. Shopify is putting an AI coding agent on the real theme files and giving merchants a live whole-store workspace so bespoke stops being the expensive path.

On Thursday, 1 October 2026, Shopify announced Canvas, a new design surface for online stores. The newsroom post is titled “Introducing Canvas: Opening the aperture on online store design.” The byline is Shopify. The page dates the post October 1, 2026. It does not print an hour. Canvas is rolling out to merchants over the coming days. Shopify says anyone, whatever their design experience, coding skills, or budget, can build a bespoke store with Sidekick, Shopify’s AI agent. A theme is the set of files that draw the store: the pages, the layout, and the look. Those lines are Shopify’s.

What the workspace shows. For the first time, Shopify says, merchants can see every page laid out together, pan across them to understand how the store feels as a whole, then zoom in to work on the details. The changelog calls that same surface an interactive, infinite workspace, so a merchant can see the whole store and work on any part of it in context. Pan means slide the view across the pages. Zoom means move in on one page, or one piece of a page. Those lines are Shopify’s.

Two ways to change a page. Merchants can still click an element and edit it directly, or work with Sidekick in the chat instead of walking through a settings panel. As Sidekick makes changes, those changes land in Canvas in real time, so the merchant can see how they feel in the context of the whole store. The changelog says that range runs from a single section to a store-wide redesign. A section is one block of a page, such as a banner or a product grid. Those lines are Shopify’s.

What is on the screen is the store’s real code. Shopify says merchants are not editing a static preview. A static preview is a picture of the page that does not run. Canvas renders the real code behind the store they are building with Sidekick. Merchants can preview each page with full interactivity and animation, and see key pages with different products, collections, and screen sizes. A collection is a group of products, such as a category. Those lines are on the newsroom post and on the changelog.

How Sidekick behaves while it builds. Shopify says Sidekick asks questions, proposes approaches, and takes feedback along the way. It remembers preferences and carries earlier design decisions forward, so the merchant can spend the conversation on new choices instead of restating old ones. Merchants and Sidekick work from the same design. Merchants review changes as they land. Sidekick takes screenshots to inspect its own work. Because both can see the result at the same time, they can try an idea and revise it together. Those lines are Shopify’s.

What a design director said the hard part was. Austin Knight, design director at Shopify, said getting Sidekick to write code was easy, and guiding it toward good design decisions took a great deal of time and attention. He said every theme has a unique design contract, a curated set of patterns to draw from, and a mountain of opinionated eval data. The result, he said, is that Sidekick brings merchants tasteful, distinct design directions they can react to. A design contract, in that sentence, is the theme’s own rules for how it should look. Eval data is the set of examples used to judge whether a design is good. Those words are his, in the newsroom post.

The coding job, as Shopify states it. Sidekick has been writing code for some time, generating apps, building custom theme sections, and making more than twenty-five million edits to themes in the first half of 2026. To take on larger store-building tasks, Shopify says Sidekick needed to move through all the templates and files in a theme, make coordinated changes across them, and judge the result. Sidekick now works directly on the theme’s files, guided by instructions and skills for building stores. Shopify also says the theme architecture has been simplified, so the store’s structure, logic, and design are easier for Sidekick to understand and change. As it builds, Sidekick validates its code and reviews screenshots of how the changes landed on Canvas. It uses both kinds of feedback to refine the work in a loop before handing the result back to the merchant. Shopify says that range runs from small section changes to store-wide redesigns. Twenty-five million is Shopify’s count. The post does not print an outside audit of that count.

What is not changing yet. Ben Sehl, director of product at Shopify and co-founder of Kotn, said the product is early and Canvas is not replacing the existing editor yet. He said things will change quickly, and there are gaps still to close. The changelog lists what is missing at launch: third-party themes from the Shopify Theme Store, Markets, rollouts, translations, and app blocks and app embeds. Themes edited in Canvas do not receive theme updates. A third-party theme is one sold by someone other than Shopify in the Theme Store. Markets is Shopify’s tool for selling in more than one country. An app block or app embed is a piece of a store that comes from an installed app. The original theme stays in the current theme editor. To start, the changelog says, go to Online Store, then Themes, and create a new theme in Canvas, or duplicate a Shopify theme or a custom theme in Canvas. The newsroom post says the rollout is over the coming days. It does not say every merchant has Canvas on the first day.

What Sehl said about the old way. He said that when he built Kotn 12 years ago, he knew how to code and it still took two weeks to get a rough store working. He said an entrepreneur on Shopify can now build a fully custom store in twenty minutes that is head and shoulders above what he built then. Twenty minutes is his comparison. The post does not print a timed study of merchants. Shopify’s own close says that for most of its history, a bespoke store meant writing code, paying someone who could, or navigating an unwieldy settings panel, and that the more creative the vision, the harder it was to realize. Those lines are Shopify’s. The twenty-minute line is Sehl’s.

What TechCrunch reported the same day. Sarah Perez’s story is stamped 9:44 a.m. PDT on October 1, 2026, which is 12:44 p.m. Eastern. The image credit on the page is Shopify. The piece says merchants chat with Sidekick, the results show in real time, and the view is the real code rather than a static preview, so a page can be tested for interactivity, animation, and different screen sizes. It says Sidekick takes screenshots so it sees what the merchant sees. It says merchants can still click elements. It says Shopify gave Sidekick direct access to theme files and simplified the theme architecture. On the gaps, TechCrunch lists third-party theme support, app blocks and extensions, markets, translations, rollouts, and theme updates as absent from the first launch, and it adds that Canvas is desktop-only. Desktop-only is TechCrunch’s line. The newsroom post and the changelog do not print those words. TechCrunch says Shopify told it those missing pieces are planned over time, because the product is still new. The piece also sets Canvas beside site builders from Wix, Squarespace, Webflow, and Framer, and beside tools such as Lovable and Replit. That comparison is TechCrunch’s. It is not a sentence in Shopify’s post.

The picture is Shopify’s launch graphic. A dark workspace fills the frame. The Shopify bag logo sits at the upper left, in green and white. White type reads Introducing Canvas, then Opening the aperture on online store design. On the left, a Sidekick chat says it created a full store from the brief, and three cards show typography, a blue color palette, and button styles. The center is a store named VESNA. A large photo shows a person in a dark jacket, with the line Designing the future of water and a Shop All button, and a product grid sits below. On the right, type reads Every page. One workspace. and Pan, zoom, and edit the whole store with Sidekick. The frame does not print a calendar date. It is the product collage from the newsroom post.

In plain terms, Shopify said on Thursday that Canvas is a new design surface, rolling out to merchants over the coming days, where every store page sits in one workspace. A merchant can pan and zoom, click an element, or chat with Sidekick, and the edits show up on the real theme code as they happen. Shopify says Sidekick now works on the theme files themselves, checks its code and its screenshots in a loop, and made more than twenty-five million theme edits in the first half of 2026. The existing editor is still there. At launch, Canvas does not cover third-party Theme Store themes, Markets, rollouts, translations, or app blocks and app embeds, and a theme edited in Canvas does not get theme updates. TechCrunch adds that the first version is desktop-only, and that Shopify said the missing pieces are planned over time.
