Unchained Engine

The Unchained Engine is our core product and is written in Node.js ES6. It exposes all data exclusively through a GraphQL API (headless). The web application is served stateless and therefore container friendly.

Core Values

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.

Headless & Hackable

Non-hackable software (like SaaS) use the technique of "customizing", meaning they provide a massive control panel where every aspect of the software can be configured, themed or disabled. Sadly there is always something that needs some extra development work and people need to hire somebody to create a plugin. In Unchained Engine, the software flow is changed through code and not through UI. This means a software developer is always required to configure the platform. It's called "hackable" software and allows to configure even parts of the software that were not intended to get configured by the core developers.

Software Stack in detail

Node JS Logo

Node.js ES6

We use the most popular programming language in the web because we think it's key for a hackable software. If you have a hackable software but no coder, what's the point then? As the project manager you'll propably always find somebody that can program in Javascript, while finding people that code in GoLang are rare. To increase the stability and longevity of our stack we further have selected Meteor.js as the build tool.

GraphQL Logo

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.


We've 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 are much easier to develop.More infos about why Meteor.js or MongoDB you can find in our FAQ
