Bringing shopping into the future: The Fall '26 Edition for developers

In Spring '26, Shopify opened agentic commerce to every developer. The Fall '26 Edition builds on that with a more connected developer platform: shopping experiences built on Shopify can now live inside any agent or app, trust runs deeper across the app ecosystem, and developers get a stronger foundation for apps and storefronts. "Developers are part of the same flywheel as merchants," says Vanessa Lee, Shopify's VP of Product. "Whatever they build makes Shopify better for the merchants who use it, that brings more merchants on board, and the next developer has even more to build for."

To explore the complete rollout, visit the Fall '26 Edition. Read a list of highlights below:

Bringing commerce into every agent and app

Developers building shopping apps and agents can now work with Shopify's Catalog, cart, and checkout directly, with structured data at every step.

Shop.dev + Shop.md: shopping in every agent or app you build

What it is: Shop.dev gives any agent or app a single connection to Shopify Catalog, sign-in with Shop, cart, checkout, and Shop Pay. It's the same connection behind shop.md, a skill that turns any agent into a personal shopper: shoppers add it from shop.md, and their agent can search more than a billion products, get recommendations based on their preferences and recent purchase history, and check out with Shop Pay.

Why it matters: Any developer can start building on the same catalog and checkout behind ChatGPT, Copilot, Muse from Meta, and Instinct, with no key required.

Universal Checkout for partners

What it is: Partners can now offer one checkout for products from different brands, with product discovery from Shopify Catalog and payment with Shop Pay.

Why it matters: Multi-brand shopping has to account for each merchant's own business needs and logic. Universal Checkout handles that, so developers can focus on building cross-merchant discovery experiences while every merchant still benefits from Shopify's checkout, rules, and orders.

WebMCP tools on storefronts and checkout

What it is: A set of tools on every Liquid and Hydrogen storefront and checkout that expose structured data and let browser agents search products, update the cart, and complete checkout once the buyer approves, with the same validation as the checkout page.

Why it matters: Every Shopify store is agent-ready by default. Agents get structured data back instead of reading screenshots and simulating clicks, so they can shop any Shopify storefront more quickly and reliably.

Catalog API filter expansion

What it is: Filter Catalog API results to products with 3D models or video, with links to their media, and get sale prices and safety warnings on every product.

Why it matters: Developers can build a shopping experience around the filters they choose, like a gift guide of top-rated products under $50 or a scrolling feed of product videos. Apps get richer results from one request, without checking each result or making a second call for media.

Building trust into the app ecosystem

Merchants rely on apps to run their business and trust them to protect their orders, customers, and revenue. Every app install is an act of trust, and protecting merchants is work we share. We are continuing to roll out security updates to give developers more ways to protect their apps.

App security checks with AI Toolkit

What it is: A single command in the Shopify CLI, part of the AI Toolkit, checks an app for the most common vulnerability patterns, such as unauthenticated routes, cross-shop data access, and unverified webhooks. Developers can then work through fixes with their AI coding assistant.

Why it matters: Developers can find security gaps in their own code: When we tested it with a small group of partners, most found something they didn't know about and were able to improve their security. We're continuing to invest in platform protections, developer tools, and guidance to make secure development easier.

More context on every collaborator request

What it is: Every new collaborator request now shows merchants how long a partner's organization has been on Shopify, where the account was registered, where the request came from, and roughly how many stores it actively works with.

Why it matters: Merchants can approve requests with more confidence. Once partners add their business details in the Dev Dashboard and complete identity verification, Shopify adds the rest to every request automatically.

Giving developers a stronger foundation

Shopify gives developers a stronger foundation so they can spend more time on what they do best: building.

Dev Dashboard and app events

What it is: A refreshed Dev Dashboard home that shows the health of every app and store at a glance, with payouts, statements, and billing in one place. Apps can also define and send events to Shopify, so merchants can analyze app activity alongside store data in Shopify Analytics.

Why it matters: Developers see what needs their attention first, with flagged apps and stores ranked by severity, while merchants see what an app does for their business without leaving Shopify.

New theme architecture

What it is: Page structure now lives in the Liquid template itself instead of a separate JSON file, with blocks, typed contracts, partial updates, markdown files that guide agents, and Tailwind styling built in.

Why it matters: Developers and coding agents can read a whole page from top to bottom, instead of piecing it together from JSON and a tree of sections. Themes built on it are also ready for merchants to edit with Sidekick in Canvas, now in early access.

Hydrogen works with any framework and any runtime

What it is: Hydrogen, rebuilt and now generally available, works with any framework and any runtime, with customer accounts, predictive search, Vue bindings, edge caching, and agent skills added since June. Vercel Shop, an open source Next.js template built on the Hydrogen SDK, is also now generally available.

Why it matters: Developers can add Shopify commerce to the stack they already have, with money formatting, markets, Shop Pay, customer accounts, and consent-aware analytics maintained by Shopify.
