Description
Astah SysML helps systems engineers capture requirements, structure, and behavior in SysML v1 without the weight of a large enterprise suite. Block definition and internal block diagrams, requirement diagrams and tables, parametric diagrams, and use case, state machine, activity, and sequence diagrams are all included, along with mind maps for early concept work.
Each diagram is a view of one shared model, so updating a requirement or block keeps every related diagram in step. Assist functions such as double-click creation, creating multiple elements from text, and alignment guides reduce drawing time. Models can be exchanged through XMI and with Cameo Systems Modeler, and profiles let teams extend the language.
For AI-assisted work, AI Chat Copilot connects to OpenAI, Azure OpenAI, Claude, Gemini, or any OpenAI-compatible endpoint through your own API key, and a local MCP server lets external AI agents read and work with your models.
Astah SysML runs locally on Windows and macOS. It does not include simulation. Developer: Change Vision, Inc. Current version: 11.0 (March 2026).
Description
Diagram.now serves as a versatile diagram editing tool designed for Confluence Cloud, and it also features a complimentary browser-based editor. As a Forge-native application developed for Atlassian, it enables users to create and save diagrams directly within Confluence, eliminating the need for an external server or the hassle of creating additional accounts.
Users can design various diagram types, including flowcharts, UML, BPMN, ERD, mind maps, cloud architecture diagrams, and wireframes. Additionally, it supports importing existing projects from platforms like Visio, Lucidchart, Gliffy, Mermaid, and SQL schemas, facilitating a seamless transition for teams looking to switch tools without the need for redrawing their work.
The application is free for teams of up to 10 users, while the browser-based editor can be accessed at no cost, even without a Confluence account. Furthermore, it represents an efficient solution for collaborative diagram creation and editing, making it easier for teams to visualize their ideas effectively.
