Everything here is built by a small workshop

MyStoreKit is a small workshop that builds Shopify apps and nothing else. Not part of a suite, not a feature bolted onto a platform. Useful features at a fair price, for the people who need them.

  • One job per app

    Each app solves exactly one problem. Simple settings, light footprint. You never pay for features you don't use.

  • Honest pricing

    Every app is $5/month with a 7-day free trial. Not part of a suite, not a platform add-on. A price from a workshop you can talk to.

  • Support from the maker

    Questions get an answer within 24 hours from the person who built the app. No chatbot queues.

Every app is the same price

There is no cheaper app with fewer features, or a pricier app with more. You pay $5/month for what you use.

How do I install an app?

Click an app's Install button to go to its Shopify App Store listing. If you're logged into your store, installation takes a few clicks.
