About the project

A clearer map of modeling tools.

NeoMBSE is an independent directory for people choosing UML and SysML tools for software architecture, systems engineering, and model-based engineering.

Why this directory exists

Tool lists often mix semantic model editors with drawing applications, platform support with browser access, and open-source software with paid hosted services. Those distinctions matter when a team makes a technical choice.

NeoMBSE makes those distinctions explicit. Each record separates platform, access method, runtime, supported standards, modeling interface, license, and evidence-backed capabilities.

Editorial independence

Vendors may submit corrections and updates, but submissions are reviewed before publication. Any future paid placement will be labeled as sponsored and will not change capability findings or editorial rankings.
