Edit SysML v2 models with Eclipse SysON, an open-source and web-based MBSE modeling tool.

Get Started Stay tuned

Standard Compliant

An implementation of the OMG’s specification SysML v2: language concepts, REST API, and textual interoperability format

Web-Based

Graphical, form-based and tabular structured editors that can be used from a web browser, without any specific installation on user's desktop

Open-Source

Hosted in the Eclipse community, SysON aims to catalyze industrial collaboration, accelerate innovation, and foster the adoption of SysMLv2

SysON was presented during the Vendor Roadmaps and Implementation Status session of the MBSE Workshop held as part of the INCOSE International Workshop 2025, in Seville, Spain, on February 1, 2025.

We're thrilled to share that we've already made significant progress toward our goals!

As demonstrated in the quick demo, SysON is up and running—packed with powerful features and designed with a strong focus on user experience.

The project is on the right track and is already generating considerable interest.

Why SysON?

SysML was created in 2005 as a standard for model-based systems engineering (MBSE) to elevate the role of models as primary tools for communication and documentation.

With system complexity continuing to escalate exponentially, and Digital Engineering emerging as a pivotal pillar to address an ever-challenging world, SysML 2.0 has been specified as the next-generation systems modeling language to improve precision, expressiveness, and usability.

SysON’s objective is to provide System Engineers with super easy access to this new standard, at minimal cost and great ease of use, with the guarantee of interoperability with other open-source MBSE tools notably Capella and Papyrus.

This will be achieved through three means: the support of the SysML 2.0 standard, the use of state-of-the-art web technologies, and an open-source approach.

Features

General View

The General View is a graphical representation that enables to display any members of a SysMLv2 model as a graph of nodes and edges.

Interconnection View

The Interconnection View is a graphical representation on which you can see how parts, that are modular units of the systems, interact with each other through ports.

Model Libraries

Model libraries are an integral part of the SysMLv2 standard for facilitating the reuse and the composition of system models between users. It is natively supported in SysON.

Textual Import/Export

SysML v2 defines a textual notation that is an additional view on the model. It allows different users and tools to exchange the content of models in a standard and human-readable format.

Capella Interoperability

SysON aims at facilitating systems engineers to seamlessly work with both SysML v2 and Capella. Exchange of architecture models with Capella will be natively supported in SysON.

Roadmap

The project team works in an iterative mode to deliver a new version every 8 weeks.
The first release of SysON, version 2023.12, was launched in December 2023 by Obeo and CEA List.
The SysON roadmap takes into account user feedback and needs identified as part of an Open Innovation approach.
For the next months, our main goals include:

Teaching & Experimentations

Achieving a first level of maturity for SysML V2 modeling with SysON, suitable for teaching, research, and industrial pilot project activities.

Industrial Collaborations

Expanding industrial collaborations, via an Early Adopter Program, to prepare for deployment and usage in operational contexts in 2026.

SysML 2.0 Compliance

Complying with the OMG SysML V2 specification, including providing a REST API and ensuring interoperability with the textual format.

In 2025, we will intensify our collaborations with industrial partners to elevate SysON to the forefront of SysML V2 modeling tool excellence
and prepare it for professional, operational, and large-scale deployment.
