Shopify released Sidekick app extensions in June 2026 and put them center stage at its DotDev developer event in Toronto the following month. The idea is simple: an installed app can expose read-only tools to Sidekick, so when a merchant asks "which wholesale accounts are going quiet?" or "how did my last email campaign do?", the answer comes from real app data inside the admin.
Adoption is still early, which is exactly why it is worth knowing which apps support it. If Sidekick is becoming the way merchants interact with their admin, apps it cannot see become invisible in daily operations.
How to tell if an app works with Sidekick
There is no badge on App Store listings yet. Three reliable signals: the listing or the developer's site mentions a Sidekick extension, Shopify's own editorial guide to Sidekick apps features it, or you simply ask Sidekick a question that only that app could answer and it requests consent to read the app's data. The first time Sidekick touches any app's data, Shopify shows a per-app consent prompt.
The suites: one vendor, several connected apps
Miko Apps (five apps, 39 Sidekick tools)
Full disclosure: the Miko suite is ours, and as far as we know it is currently the widest Sidekick coverage from a single vendor: every one of the five apps ships an extension.
- Miko B2B Wholesale House: wholesale pricing per group, volume breaks, net terms status, pending registrations, purchase orders, and a quiet-accounts check that flags wholesale customers whose ordering rhythm is slowing.
- Miko Loyalty & Rewards: member lookups, top members, tier breakdowns, program stats, and how many members are close to a reward.
- Miko Claude AI: churn risk, RFM segments, top customers by lifetime value, plus actions that set up a win-back email or re-engagement campaign which you confirm inside the app.
- Miko AI Descriptions & Narrate: content coverage across the catalog, generation quota, bulk job history, and how many products have audio narration.
- Miko Product Rentals: overdue rentals, upcoming bookings, availability checks for a date range, and rental revenue.
Marketing and email
Klaviyo, Mailchimp, Bloomreach, and Seguno all ship Sidekick extensions, oriented around campaign and flow performance questions. If email is your revenue engine, this is the category where Sidekick answers save the most dashboard time.
Loyalty and reviews
Smile.io covers loyalty program activity. Judge.me and Yotpo cover review volume and sentiment questions. Miko Loyalty (above) is the alternative if you want loyalty answered by the same vendor stack as your wholesale and churn data.
Operations, returns and fulfilment
Loop Returns and AfterShip Returns answer return-activity questions. Printful covers print-on-demand order status, and Syncee covers sourcing. Matrixify-style data tools are starting to appear as well.
Discounts and merchandising
Discount Kit, Abra, and Checkout Links expose promotion setup and performance. Bundle Builder answers bundle questions. For wholesale-specific pricing questions (tiers, quantity breaks, per-group prices), Miko B2B Wholesale House is the one built for that job.
What Sidekick extensions cannot do
Two guardrails worth knowing. Data tools are read-only: Sidekick cannot silently change discounts, delete members, or edit content through them. Where an app offers an action, Sidekick navigates the merchant into the app to confirm it there. And extensions only answer within the app's domain: a well-built extension says "open the app for that" instead of inventing an answer.
The honest state of the ecosystem
Most of the App Store does not support Sidekick yet. The apps above are early movers, and Shopify has signalled clearly, with dedicated DotDev sessions on Sidekick-driven app engagement, that this surface is where admin workflows are heading. If a category matters to your operation and your current app is not on this list, it is a fair question to send its developer.
Try it in two minutes
Install any Sidekick-enabled app, open Sidekick in your admin, and ask a question only that app could answer. If you want the widest single-vendor coverage, start with the Miko suite: five apps, 39 tools, free plans on four of them. Questions? Talk to the team.
