When UML modeling drives your development process, you need a tool specifically designed for UML that can provide you with all the functionality you need - without being too complicated. That's Asta UML. Astah UML is a simple and easy-to-use tool that allows you to create the required UML diagrams.

Modern UML diagrams

UML 2. x was taken into consideration during the design process.

Astah is even faster than Excel or non UML specific drawing tools. Our software will allow you to create a set of UML 2. x diagrams for your project, including:

1. Class diagram
2. Use case diagram
3. State machine diagram
4. Activity diagram
5. Sequence diagram
6. Communication diagram
7. Component diagram
8. Deployment diagram
9. Composite structure diagram
10. Mind map

It's simple

Use auxiliary functions to work quickly and efficiently.

For over 10 years, we have been integrating user feedback. The result is a powerful software program that is very easy to use and learn. Astah UML provides various "auxiliary" features to make your work faster, including:

1. Automatically create class diagrams
2. Alignment Guide
3. Copy to MS Office document
4. Automatic Layout
5. Customize shortcut keys
6. Gap expander/remover
7. Map View
8. Merge project files
9. Search and Replace
10. Display relevant classes/models
11. State transition path and table

Make it your own tool

A large library of plugins and integrations.

Do you need out of the box functionality? no problem! Thank you to Astah Friends and our extensive plugin and integration library for customizing Astah UML to meet your needs. Plugin can be used for code generation, reverse engineering code, export, usability, and more. In addition, Astah UML integrates with Atlassian's Confluence, yUML, and Freemind.

Use our API to extend functionality.

The Astah API enables you to obtain Astah model information, create and modify charts and models, and use them in application software. Using our API guide, you can also create your own plugins and submit them to our library!

Beyond and beyond again

Reverse engineering or code generation

Use our code generation tool to directly generate code from your charts, making your models come to life. Or work backwards and reverse engineer your project to create a model. Astah UML supports reverse engineering of Java, C #, and C++.

Import and Export

Modeling is an excellent way to convey your ideas, but you may need to extract this information from Astah UML and get it into the hands of your colleagues. With Astah UML, you can export charts to various formats, including image files (jpg, png, emf, and svg), RTF documents, and HTML. You can also copy and paste into Microsoft Office documents and use custom settings for printing.

Do you want more?

Astah UML itself is a powerful tool, especially when you are a student, working independently, or just starting to model. However, if you want more features, please consider upgrading to Astah Pro. It provides all the features of Astah UML and more!

1. More types of charts

In addition to UML 2. x diagrams, ER diagrams, flowcharts, and requirement diagrams can also be created in Astah Pro.

1. Collaboration among larger teams

Pro provides effective collaborative modeling capabilities when working with large or remote teams.

1. Multi language support

Give each model a dual name - English& Portuguese, German, etc. It is particularly helpful for offshore development.

1. Other licensing options

Astah Pro offers more licensing options, including perpetual licenses and academic discount licenses.
