The Most Flexible E-Commerce Platform

The headless approach allows you to build e-commerce apps which run natively on mobile phones, watches, TVs, wearables, and your own hardware. It empowers developers to integrate proprietary and decentralized systems, bridging digital commerce with distributed ledgers & IoT.
By using open-source technologies & popular programming languages, it is very easy for developers to extend and adapt the platform to a company's specific needs. This enables product owners to design like never before.

Built for Developers

There is no UI. Just build your own interface on top of the GraphQL API. If you want to connect your existing back-ends or add a cryptocurrency as a method of payment, simply write a small plugin, build your own module, add a micro-service, fork the whole thing, or just extend the GraphQL API with your own queries & types.

All you need is some Javascript. (Node.js) know-how, and our multi-channel enterprise shop system.

To make it even easier, we have created a boilerplate template with all the required initial setups. All you have to do is, copy the code below and execute it in a command line, scaffold a template that suits you, and start developing with Unchained in less than a minute.

npm init @unchainedshop

Open Source

Usage of OSS prevents vendor lock-in. Using software that is open to the public leads to communities that help each other, the software is resilient to economic issues like bankruptcy of the software owner.


Your Front-End

Integrate your iOS app, Android watch, website, or even car.
Connect the Unchained GraphQL API with your front-end of choice & build the perfect customer experience.

Your Back-End

Simply add your CRM, ERP, PIM. We already successfully connected the Unchained Engine to various core systems such as Microsoft Navision and crossbase, as well as smallinvoice and Google Sheets. API available? Go!

What is Hackable?

Non-hackable software (like SaaS) uses the technique of customisation, meaning it provides a massive control panel where every aspect of the software can be configured, themed or disabled. Sadly, there is always something that needs additional software development work and requires creating a custom plug-in.

In Unchained Engine, the software flow is changed through code and not through UI, which means a software developer is always required to configure the platform. Our hackable software provides you with basic out-of-the-box customisation, however it allows for the business logic to be fully-customized by the developer. This is achieved through a staged approach ranging from plugins to a full hard fork.

Quick Sample

Software Stack in Detail

Node.js ES6

We use the most popular programming language on the web because we think it is key for a hackable software. If you have a hackable software but no coder, what is the point then? As the project manager you will propably always find somebody that can program in JavaScript, while finding people that code in GoLang are rare.

Apollo GraphQL Server

GraphQL is the new REST. Having a schema on the API helps with connecting systems in a micro-service architecture and makes it extremely easy to implement in client apps for all kind of operating systems and programming languages. When adding, removing, and migrating back-end data stores, the API doesn't change from the client's perspective. It's simple to add new types and fields to your API, and similarly straightforward for clients to begin using those fields. This helps design, develop, and deploy features quickly.


We have chosen MongoDB because it is the most popular NoSQL DBMS out there. With a schema-less database, development of plugins and extensions that need to extend the existing data structure is much simpler. The document data model is a powerful way to store and retrieve data that allows developers to move quickly. MongoDB’s horizontal, scale-out architecture can support high volumes of both data and traffic.
