Tailor Astah to fit your needs with free add-ons! This library of plug-ins has been developed by Astah and Friends of Astah to help further customize the software. Learn more about the options already available, or build your own Astah plug-in.
* No technical support is provided for listed plug-ins.
If you have any ideas that you’d like to implement via Plug-ins to Astah SysML, check out this “Astah plugin ideas” repository Zsolt Sandor, Friends of Astah / a founder of Systems Engineering Professionals Community launched!
Don't see what you're looking for, or want to further customize Astah to your own needs? With our SDK, API, and extensive tutorials, you can.
“Astah Easy Diagram Plug-in” – Developed by one of our innovative customers, this tool is tailored to make your diagram editing tasks not only easier but also more enjoyable.
The Astah Legend Plug-in enhances your modeling tool experience by seamlessly incorporating legend capabilities. The plugin enables coloring of diagram elements based on rules described in Groovy language.
Generate a comprehensive Matrix to visualize the interdependencies among model elements in Astah SysML and Astah System Safety.
Astah Mermaid Plug-in enables you to convert Astah’s Class diagrams and Sequence diagrams to a Mermaid diagram source file.
Import UML Class diagram from miro to Astah and vice versa. Also an import of mind map from miro is supported.
Refine SysML models with the Astah Model Validator Plug-in. Create custom Groovy-scripted validation rules in YAML files, and efficiently detect and correct rule violations!
Astah Profile Plugin is a cutting-edge solution for adding profile editing capabilities directly within Astah. Streamline your workflow with enhanced customization and efficiency.
Create detailed, formatted text documents directly within Astah for each model element.

ClasHStamP aims to support Model-Driven Software Engineering with structure and behavior round-trip source code generation.
Upload .astah diagrams into Atlassian’s Confluence using Macro.
Due to the end of Atlassian Server support on February 15, 2024, we will be discontinuing the Astah x Confluence Plug-in on March 31st, 2024.
Easiest way to import database tables into Astah, and auto-generate ER Diagrams with imported tables quickly.
Drop Calendar into a diagram when you need it. Best for when you are making plans using Mind Map.
Generate Dependency Structure Matrix (DSM) to show dependency relationships between Classes, Interfaces and Packages. DSM quickly alerts you to overly specific dependencies and circular references in a concise color-coded chart.
Visualize your software design in Astah instantly from your repositories like Github, Bitbucket with just a drag and drop! (Currently it works with Java source code only.) Also import .java files via a drag and drop is available!
Insert a picture directly into Note to boost the expression of your models and make your diagrams more intuitively understandable.
Add a view to check the consistency between Class diagram models and Sequence diagram models.
An educational tool to help introduce object-oriented programming and software modelling for the high school or early university level.
Powerful Plug-in to add 4 major functionalities to your Astah. Source code generation, Model Preview, Diagram Map and Relation Matrix.
Generate source code from Class diagrams and Statemachine diagrams to any lanauage you want. Sample templates for C++ (GR-SAKURA) included.
Embed Astah diagrams directly in documents of the Microsoft Office products (Word and Excel..etc).
Make it easier to show your models at presentation by bookmarking specific models in diagrams. At team-meeting, just click the bookmark to focus the model on the screen.
Speed up your modeling by using the keyboard commands. Works like Alfred tool for Mac!
The plugin converts models on Class diagrams, Activity Diagrams, Block Definition diagrams and Mindmaps created in Astah Products to GSN (Goal Structuring Notation) models.
State Transition Paths serve to monitor and predict the actual behavior patterns of the software that you are modeling. Use Transition Paths as test cases to assure they correctly reflect the software’s true behavior.
State Transition Tables give you a different perspective of your model. State Transition Tables enables you to easily monitor and report on the most complicated State Machine Diagrams, revealing subtle errors before they have widespread effects.
Manage Astah files with Subversion. Add [Commit, update, compare change] menu in Astah directly works with Subversion.
Create the C4 model diagrams in Astah for visualizing software architecture.
