This post provides overviews achievements of the recent quarter and outlines short- to medium-term development priorities for our SysML tool ecosystem (now Syside & Sysand). It is part of our quarterly roadmap updates.

Disclaimer: This blog post outlines upcoming features and developments for Syside & Sysand. Please note that these details are shared for general awareness of direction and may be subject to change over time due to evolving circumstances. Plans and timelines can shift as projects progress, and any updates or releases will ultimately be determined by Sensmetry

Achievements in 2025 Q3

2025 Q3 achievements summarized as a milestone:

We have all the necessary & mature-enough SysML v2 tools to take advantage of SysML v2 & unlimited automation capabilities now, provided you prefer code as the authoring format and software engineering workflows for collaboration (including Git tools, package managers, and CI/CD). 

Let us have a more detailed overview of the main achievements:

• Sysand – the long-awaited open-source SysML v2 package manager has been released! Being tool-agnostic, justifies a different name (the former working title was ‘Syside Librarian’); the website and public package index are available at sysand.org. The open-source repository for the client is available on GitHub. For more information about Sysand, read this blog post.
• All Syside tools now support the official SysML v2.0 release. Syside tool family was updated to support the 2025-07 release of SysML v2, which is also the latest and official release of the language specification. Read our announcement.
• Syside Modeler is now available for download through the VS Code marketplace, making installation easier.
• Syside Modeler now provides its own language support features, offering a 50x speed-up, rather than relying on SysIDE Editor Legacy (see below), after achieving feature parity with it. For more info, see performance details.
• Syside Modeler CLI has been released, supporting validation and formatting features from the command line interface.
• Syside Editor is reborn to use the same processing engine as behind the Syside Pro Suite tools. This means that users experience a 50x speed-up in performance, resulting in significantly quicker updates and bug fixes. A new Syside Editor is available on the VS Code marketplace and Open-VSX for installation and use within VS Code, Cursor, and VS Codium, as before. The old Editor got the ‘SysIDE Editor Legacy’ title and was deprecated. For more information about the change, read this blog post.
• Syside for Educators is used widely by industry leaders in SysML v2 training. Syside for Educators is a cloud-based Syside Pro Suite for teaching SysML v2. Public events powered by it included the official SysML v2 training at INCOSE IS 2025, given by Sandy Friedenthal and Frank Salvatore, as well as the SysML v2 training at INCOSE Western States Regional Conference by Chris Armstrong. For more information about Syside for Educators, refer to its product page.
• Syside Automator high-level model-building API is released for closed-beta testing by early adopters. If you are interested in this and future high-level API closed beta releases and are ready to provide feedback, please contact us at syside@sensmetry.com.
• Syside Pro Suite is available for purchase through our self-service website for individuals. Plans for teams and businesses are ordered as explained on the pricing page.
• SysML v2 Cheat Sheet released for INCOSE IS 2025 has been a success, available online as adaptive HTML to use on any device (tip: bookmark or pin to home screen) or as a PDF to print and stick to the wall. 

Main goals for 2025 Q4

Having released the base functionality to work with SysML v2 as code in production, as outlined above, the primary focus of 2025 Q4 is on improving the user experience of the tools, particularly Sysand and Syside Modeler. Let us list out the plans for different tools.

Syside Modeler

• Implement a model tree view. This tree will display the elements from your entire model and allow you to navigate through your models more efficiently, including supporting element filtering. This is an improved version of the Outline view (available currently on the latest versions of Editor and Modeler), which only displays elements of the currently opened file.
• Integrate Sysand into Syside Modeler and Editor to introduce the concept of “SysMLv2 projects” and facilitate seamless dependency management.
• Implement a first version of Table views. Production feature might take longer than Q4, but we aim to have initial versions available for beta testing in Q4.
• Improved generative AI support for KerML & SysML v2 files within VS Code & Cursor IDEs.
• Significantly improve diagram visualization capabilities, working in close partnership with Tom Sawyer Software. This includes:
  • Integration of the latest release of Tom Sawyer’s SysML v2 Viewer, supporting more diagram types and features.
  • Improved support for different diagram layouts, such as sequence diagrams or state machine diagrams.
  • Diagram export through the Syside Modeler CLI. We are actively working with Tom Sawyer Software to bring a satisfactory solution for all stakeholders. This is a top priority feature for us, but not everything is under our control. 
  • Ability to visualize selected model fragments.

In parallel with the above, we will continuously keep up with SysML v2 specification updates and bug fixes.

Sysand – the package manager for the SysML v2 ecosystem

Sysand is our brand-new, open-source, and tool-agnostic package manager for the SysML v2 ecosystem, providing a reference implementation for a crucial part of the KerML specification (for more information about Sysand, see our blog post). Released under a permissive open-source license, Sysand is available for anyone to use and for any tool vendor to integrate, ensuring tool interoperability and conformance with the specification.

• Throughout Q4, we will continue to improve Sysand’s maturity & usability based on user feedback and our own learnings. We will also work to support the SysML v2 user community in growing the number of packages on sysand.org. We encourage you to show your leadership and share any SysML v2 libraries publicly on sysand.org by following the submission instructions.
• Starting from Q4, we will also offer assistance with setting up Private Indexes to enable secure package sharing within your organization. Interested? Reach out to us at sysand@sensmetry.com.

We, of course, will not forget other tools from our Syside family:

• Automator
  • The main goal of Q4 will be to refine the design for our high-level model querying APIs. For this task, we are strongly dependent on our users and are looking to hear about the use cases that you would like to use our high-level APIs for. Additionally, if you are interested and ready to supply us with feedback, you can also start using our high-level API in a closed beta release. In any case, reach out to us at syside@sensmetry.com.
• Editor
  • Since Syside Editor is now powered by the same engine as Syside Modeler, expect more rapid bug fixes and performance improvements.
• Syside for Educators
  • After a successful Q3 for Syside for Educators, which powered many trainings and workshops, we will be working hard to improve this offering and make it even smoother to use, both for educators and participants.
  • A major update is planned to allow users to use Syside Automator during workshops and classes.
  • We are also learning many valuable lessons while developing Syside for Educators, which we are applying to our upcoming Syside Cloud (working title) offering. However, this is still some time away, but keep an eye out for further announcements from us.
  • Interested in using Syside for Educators yourself? Learn more on our website.

Looking further ahead: 2026

The medium- to long-term vision and driving forces behind the development of Syside remain the same:

To liberate organisations to unlock unlimited automation potential across the system lifecycle – 

to make superior systems, much faster!

Main themes for 2026:

• Continued KerML & SysML v2 processing engine & infrastructure development to support the most ambitious use cases of our users. 
• Continued development of Syside modeling tools to reach maturity & ease of use for large-scale adoption.
• Syside cloud-based solution for production use to take advantage of the cloud computational infrastructure.
• Open interoperable ecosystem & worldwide user community enablement through providing infrastructure for managing SysML v2 libraries (yes, Sysand!) and associated applications. 

Having said all this, in the end, we are driven by the needs of our users, who shape and update our priorities, and whom we exist to enable – to build superior systems, much faster!
