Modelix Overview

The goal of this quick overview is for you to understand, what modelix is, what it is not and how it might be utilized.

What is Modelix?

Modelix is a platform to bring models to the web. It consists of multiple components, which can be combined in different ways to support a variety of use cases.

It is important to note, that modelix is neither a language workbench in the traditional sense nor a one-size-fits-all solution. The modelix project aims to provide you with building blocks, which empower you to construct your own application with ease.

Essential components

The following table gives an overview over essential components, which you are very likely to encounter when using modelix. For a full list of components check out the components table.

Component Short description


Untyped API, which allows to interact with models.


Server, which persistently stores models.


Client, which implements the model-api and connects to a model-server.


Component, which generates a typed, domain specific API based on a metamodel definition. The generated API wraps the untyped model-api.

Basic example using essential components

As a basic example, you might want to create a web app, which manipulates domain-specific models. In this case we assume a metamodel for such models exists as part of an MPS project.

example essential components

The image above shows how the essential components work together to form the backend for a web application. In this case the metamodel definition is generated from the structure aspect of a language in MPS. For a different use case it could also be from another (custom) source.

The web application can then use the domain-specific API to manipulate and store models in the model-server.

Of course, this example only scratches the surface of what is possible with modelix.

Modelix workspaces

Apart from the individual components, modelix can also provide a system called workspaces. It consists of multiple docker images, which run in a kubernetes cluster. Among other features, this system enables users to use projectional editors inside their browser by running MPS instances in the cloud.

What’s next

Modelix is always evolving. If you want to learn more about what is coming, check out the roadmap.
