About

Astah UML is a powerful, easy-to-use diagramming tool tailored for creating UML diagrams in software development. It supports a wide range of UML 2.x diagrams, including class, use case, sequence, activity, and component diagrams, and provides users with tools for designing and managing complex projects. The platform features assist functions to speed up diagram creation, such as auto-creating class diagrams, alignment guides, and auto-layout. Additionally, users can integrate with other tools like Miro, PlantUML, and yUML, and customize the platform through an extensive library of plug-ins. Astah UML also supports reverse engineering of Java, C#, and C++ code and offers seamless code generation from diagrams. Diagrams can be exported in multiple formats, and the platform integrates well with office applications. It’s suitable for students, individual engineers, and development teams, making it a versatile tool for both learning and professional use in software modeling.

About

TopoAI is web-based diagram software for creating and refining structured, editable network, cloud, security, and IT infrastructure topology diagrams. Users can start from written technical requirements, professional templates, sketches, reference images, icon libraries, or a blank canvas. Natural-language instructions and direct canvas tools make it easy to add or remove devices, reconnect paths, update labels, organize zones, and adjust layouts. Built-in and private icon libraries support consistent visual standards, while save, export, share, revisit, and reuse workflows help teams produce proposals, architecture reviews, documentation, implementation plans, and handoff materials.
