What shipped
Shopify has launched Canvas, a tool that lets a merchant build and change an online store by talking to Sidekick, the company’s AI agent. TechCrunch reported the launch on 1 October. The merchant describes what they want; the store redraws while they watch.
The claim Shopify is making is narrower and more interesting than “AI builds your website”. What Canvas renders is the actual code behind the store, not a static preview, so a merchant can click through the page’s interactivity, watch its animations run and check how it behaves at different screen widths without leaving the builder. The whole store can be viewed at once, zoomed into and panned around, and individual elements can be clicked and edited directly rather than described to Sidekick.
How they got there
To make that work Shopify changed two things: Sidekick’s capabilities, and the theme architecture itself, which it simplified so the agent can manipulate theme files directly. That second part is the engineering decision that matters. An agent editing a constrained, legible file format is a tractable problem; an agent editing an arbitrary theme is not.
TechCrunch puts the result at a customised store in roughly twenty minutes, against weeks previously even for someone who could write the code. That figure comes from the launch coverage rather than from an independent test, and twenty minutes to a store is not twenty minutes to a good store.
What it cannot do yet
Canvas is desktop-only at launch. Several things merchants rely on are missing: third-party themes, app blocks and extensions, markets, translations, rollouts and theme updates. For a Shopify merchant of any size that list is the difference between a tool and a toy — translations and markets in particular are how a store sells in more than one country.
The competitive context is crowded rather than empty. Wix, Squarespace, Webflow and Framer all ship AI site builders, and the vibe-coding platforms are pushing from the other direction. Shopify’s advantage is not the chat interface; it is that the thing being edited is a Shopify store, with the checkout, catalogue and payments already attached.
What to watch
When third-party theme support lands, because that is when Canvas either works with the existing theme ecosystem or quietly replaces it. Whether the simplified theme architecture becomes the default for all stores rather than a Canvas-only path. And whether merchants who build this way can still hand the result to a developer afterwards.
