Edit SysML v2 models with Eclipse SysON, an open-source and web-based MBSE modeling tool.
An implementation of the OMG’s specification SysML v2: language concepts, REST API, and textual interoperability format
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.

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.
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.

Mara thought of the panes—the woman with the laugh, the protests, the watch fixed with a spoon. She thought of the price people paid for forgetting: peace, yes, but also the slow theft of what made them human. She powered a quiet loop into the machine, a sequence the merchant had slipped her: a reversal keyed to the archive's own cadence. Hot51 shivered as if waking.

The first time the designation blinked on Mara's handheld, she thought it was a joke: an alphanumeric ghost stitched from someone else's logbook. Si Gemoy Tobrut Doyan Omek Muncrat read across the header, followed by the impossible little tag: ID 56715486 — Hot51. It hummed with a frequency the city had stopped advertising years ago, an old-world marker for things meant to be hidden.
