Merx – Plugin to create online shops with Kirby 3


One day I recklessly said “building online shops couldn’t be that difficult” (Everyone laughed, because they knew). However the agency I’m working for gave me the opportunity to build an online shop with Kirby 3.

Years Months later I came back with a Kirby plugin, which I want to share with you:

I/we would be more than happy to hear what you think about it. If you have any questions or feature request please feel free to post them here in the forum or, if you prefer, you can send me a mail.



Thanks, Tobias! This looks like a great start. How customizable are the product options? For example, is it possible to add shipping and inventory to a product?

A couple of more advanced feature requests: digital product downloads and country-specific shipping prices.



Thanks for your reply.

Shipping costs are not part of this plugin. However, the plugin is meant to be extensible, so adding shipping costs, inventory and digital product donwload should definitely be possible – and documented in the Cookbooks.

Let me think about it and I’ll write cookbook recipes for these things.

I’m not sure if product options are possible with the current state of the plugin, if not it definitely will be added in a future release of Merx.

Great! I’ll definitely be keeping an eye on this and plan to give it a try.



Digital Product Downloads

After the payment the user is sent to a unique order page (e.g. where you can offer a unique download link (e.g. And/or you can sent a mail with the unique download.


If you think shipping as an own product you can create a shipping “product” and add this “product” to the cart. Maybe this is not the ideal solutions but it works for now. If you think this is too shaky and unintuitive we can think of another solution for the shipping problem. We are open for your feedback.
