dactory
Modern SysML v2 text editor that grows into a complete Model-Based Systems Engineering (MBSE) development environment.
Start with Dactory Basic - a powerful, free text editor with syntax highlighting and validation. Dactory Pro (Coming soon) will offer advanced graphical editing and complete MBSE features.
One application, one download. Your license unlocks the features you need.
Why SysML v2 is the Future of MBSE
SysML v2 represents a fundamental shift in how we approach Model-Based Systems Engineering
Text-Based Modeling
SysML v2 uses a human-readable, text-based syntax (KerML) that integrates seamlessly with modern development workflows. Write models like code, version them with Git, and collaborate like software engineers.
Round-Trip Engineering
Edit models as text or visually - changes sync automatically. The text representation is the single source of truth, enabling true round-trip engineering between textual and graphical views.
Modern Tooling
Built for the modern engineering workflow. Leverage version control, CI/CD pipelines, code reviews, and all the tools that make software development efficient and collaborative.
Precise Semantics
SysML v2 provides a more precise and expressive language for systems modeling, with better support for complex system behaviors, constraints, and relationships.
The Evolution of MBSE
SysML v2 moves beyond traditional diagram-based tools that lock models in proprietary formats. By embracing text-based modeling, SysML v2 enables the same collaborative, agile, and scalable practices that have transformed software development.
Dactory is built from the ground up to leverage these advantages, providing a modern toolchain that grows with your MBSE needs.
