Submission declined on 5 February 2026 by DoubleGrazing (talk). This draft's references do not show that the subject meets Wikipedia's criteria for inclusion. The draft requires multiple published secondary sources that: provide significant coverage: discuss the subject in detail, not just brief mentions or routine announcements; are reliable: from reputable outlets with editorial oversight; are independent: not connected to the subject, such as interviews, press releases, the subject's own website, or sponsored content. Please add references that meet all three of these criteria. If none exist, the subject is not yet suitable for Wikipedia. If you would like to continue working on the submission, click on the "Edit" tab at the top of the window. If you have not resolved the issues listed above, your draft will be declined again and potentially deleted.

SysIDE (Systems Integrated Development Environment) is a comprehensive tool suite that provides additional functionality for the SysML v2 modeling language. Developed by Sensmetry, these tools are aimed at enhancing the experience of systems engineers.

The tool suite is currently comprised of three independent modules:

• Editor. A free, open source Visual Studio Code extension that provides real-time syntax highlighting, semantic validation and other quality of life features;
• Automator. A tool that provides the ability to import the SysML v2 model into a Python environment. This facilitates custom validation rules, automatic model creation and general software development capabilities;
• Modeler. A modeling environment that brings a graphical visualization to text-based SysML v2 models by making use of Tom Sawyer Software.

SysIDE was developed by Sensmetry in response to the growing adoption of model-based systems engineering (MBSE) in the space industry. The idea behind SysIDE started with the release of SysML v2 Pilot Implementation. When trying to make use of it in internal projects, Sensmetry ran into lack of functionality which made application in real-world systems engineering difficult^[1]. This motivated the development of a tool now known as Editor. As it became apparent that others faced similar issues, the project was released as open source to be publicly available. This eventually led to a published paper, which received the Best Paper Award^[2] at Model-Based Space Systems and Software Engineering workshop in 2024.

Due to positive feedback from other systems engineers^[3], Sensmetry expanded SysIDE to provide more functionality that was missing from the Pilot implementation – this led to the release of Automator in September of 2024, and Modeler in February of 2025.
