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
dbdiagram.io is an easy-to-use and free platform that allows users to create database diagrams, or ERDs, by simply entering DSL code. Utilizing the widely recognized DBML format, users can effortlessly generate an ER diagram that appears in real time, keeping their hands on the keyboard without interruption. You can produce stunning PDFs of your ER diagrams for internal distribution, proving that creating ERDs doesn't have to be a complicated task. Furthermore, sharing your diagrams with colleagues and clients is just a click away, and if you work with popular web frameworks such as Rails or Django, you can conveniently upload your schemarb or models.py files to streamline the process even further. This makes dbdiagram.io an invaluable tool for anyone looking to simplify their database design experience.
