Instead of keeping SysML v1 models, hazard analyses, and safety arguments in separate tools, you work in one project: model the system in SysML, analyze it with STAMP/STPA, argue its safety with GSN/D-Case assurance cases, and describe safety concepts with ASAM SCDL. UAF is supported for architecture modeling. Because everything shares one model, your analysis stays consistent and traceable. You can reuse SysML blocks as STPA components or turn requirements into GSN goals instead of re-entering them, and teams in automotive, aerospace, railways, robotics, and medical devices use it to build safety cases for standards such as ISO 26262. SysML models can be exchanged with Cameo Systems Modeler through XMI. AI Chat Copilot lets you create and refine models in plain language, and a local MCP server lets AI assistants such as Claude or ChatGPT work with your models, using your own API key from the AI service you choose. Astah System Safety runs on Windows and macOS. Please note that it does not include FTA, FMEA, or simulation. Help is available by email, along with an online manual and FAQs, and a 40-day free trial lets you evaluate it on a real project. > > Verdict: Rated **4.5/5** by 4 users.

Monthly licenses are currently not available; contact Change Vision if you need a monthly or custom-duration license. Per-seat floating prices decrease with larger packs. For universities, the Faculty Site License covers Astah Professional, Astah SysML, and Astah System Safety for all faculty and students in a department. A 40-day free trial is available with no credit card required. AI features (AI Chat Copilot and the local MCP server) require your own API key from a supported AI service. API usage is billed separately by that service provider. Astah System Safety supports SysML, UAF, STAMP/STPA, GSN/D-Case, and ASAM SCDL. It does not include FTA or FMEA, and it does not run simulations. - **Target Audience**: Self Employed, 2–10, 11–50, 51–200, 201–500, 501–1,000, 1,001–5,000, 5,001–10,000, 10,000+ - **Deployment & Platforms**: Mac (Desktop), Windows (Desktop) - **Supported Languages**: English, Japanese - **Available Countries**: Afghanistan, Albania, Algeria, American Samoa, Andorra, Angola, Anguilla, Antigua & Barbuda, Argentina, Armenia, Aruba, Australia, Austria, Azerbaijan, Bahamas, Bahrain, Bangladesh, Barbados, Belarus, Belgium and 209 more ## Features - AI Copilot - API - Data Import/Export - Document Management - Drag & Drop - Ease of Use - Graphical User Interface - Help Guides - Mind Maps - Multi-Language - Multi-Language Support - Offline Access - Risk Analysis - Third-Party Integrations ## Integrations (4 total) - Claude - Gemini - Microsoft Excel - Openai ## Support Options - Email/Help Desk - Knowledge Base ## Category - [Diagram Software](https://www.softwareadvice.ie/directory/4275/diagram/software) ## Related Categories - [Diagram Software](https://www.softwareadvice.ie/directory/4275/diagram/software) - [Safety Management Software](https://www.softwareadvice.ie/directory/4699/safety-management/software) - [App Development Software](https://www.softwareadvice.ie/directory/4499/app-development/software) ## Alternatives 1.

It provides guidance in the conceptual design of safety critical Maritime systems. The SysML provides us with the functionality we need without exposing the team to too much choices and functionality. The result is a clean and easy to use user interface. > > **Cons**: The integration between STPA and SysML can probably be improved. It is a possible to create hyperlinks between components / blocks and relations, but a more thorough and conceptual integration might be very useful. What also might be useful is a way to structure the STPA model similar to applying a package / folder structure in SysML. STPA Components can be used for that but it is somewhat awkward. > > We are working on defining the system \& software architecture of unmanned maritime systems. From the onset of the project it was decided to use SysML to capture knowledge and be able to communicate this in and outside the project team. The team is relatively unexperienced with the use of SysML and this is where STPA helps to structure. So far this worked. ASTAH Support are really helpful in this process too. ----- ### "User Friendly" — 5.0/5 > **Shufeng** | *30 September 2022* | Automotive | Recommendation rating: 9.0/10 > > **Pros**: I am using the software mainly for STPA/CAST analysis. I found that drawing the control structure (as part of the analysis) using Astah System Safety is really user friendly with very flexible user interface to customize/modify the diagrams. > > **Cons**: The software in its current version does not support customization, which makes it difficult for researchers who would like to explore and test extension/modification of the STAMP methodology using Astah. ----- ### "Vikas Ghatge" — 4.0/5 > **Vikas** | *22 June 2023* | Education Management | Recommendation rating: 7.0/10 > > **Pros**: GSN software to develop safety assurance case. > > **Cons**: GSN is not compatible with GSN Community standard ----- ### "Happy user" — 5.0/5 > **Vikas** | *2 November 2022* | Research | Recommendation rating: 10.0/10 > > **Pros**: Connecting elements is very easy. GUI is decent. > > **Cons**: Not in line with recent version of GSN 3. Bit of struggle with coherent numbering of core elements of GSN. > > My overall experience is really good. I have become used to with this software due to its ease of use. ## Links - [View on SoftwareAdvice](https://www.softwareadvice.ie/software/368155/astah-system-safety) ## This page is available in the following languages | Locale | URL | | en | | | en-AU | | | en-GB | | | en-IE | | | en-NZ | | ----- ## Structured Data
