NextPSA brings a fresh approach to probabilistic risk analysis — combining cloud accessibility and a user-friendly interface. Designed for teams of all sizes, NextPSA eliminates the need for complex setups or specialized IT knowledge. Whether you're conducting a simple study or managing large-scale safety assessments, you can work from anywhere, and focus on insights, not infrastructure.
Discover how NextPSA combines smart design and cloud-based convenience to make risk analysis easier and more efficient.
NextPSA provides a secure and scalable cloud storage. Users can upload, organize, and manage their models and result files in a centralized environment.
Whether you're conducting detailed risk assessments or collaborating on large-scale projects, our cloud storage ensures your data is safely stored and ready for action.
The Fault Tree Editor is an intuitive tool for creating and managing fault tree analyses. It supports various gate types, events, common cause failures (CCF) and logical operators, allowing users to model system failures.
A Preview Quantification feature provides quick, approximate quantification results. It helps users to obtain early feedback and to gain rapid insights into system reliability without waiting for detailed computations.
The Result Dashboard offers a comprehensive visualization of cutsets, allowing users to interpret and analyze the results of fault tree analyses.
With interactive charts and graphs, it helps to identify potential weak points in a system.
Most PSA tools are complex, expensive, and not built for small teams or academic projects. NextPSA offers a simpler, more accessible solution — without sacrificing reliability.
| What Other Tools Often Do | What NextPSA Does |
|---|---|
| Require heavy desktop installation | ✅ 100% web-based, no setup needed |
| Offer overly complex, outdated UIs | ✅ Clean, modern, and focused interface |
| No built-in model verifications | ✅ Systematic execution of model consistency checks |
| Use closed, proprietary file formats | ✅ Models are open and accessible — no vendor lock-in |
| Costly licenses not suited to small teams | ✅ Free during beta for research and small projects |
| Limited collaboration and sharing options | 🚧 Collaboration tools in development — shape them with us |
| No automation of fault tree quantifications | 🚧 Automation planned in roadmap |
NextPSA is designed to support engineers, educators, and researchers who want a simpler way to model and analyze probabilistic safety without the overhead of traditional tools.
Quickly prototype and refine fault trees without licensing constraints. Ideal for agile safety studies and budget-sensitive projects.
Teach PSA concepts and experiment with fault modeling in a user-friendly environment. Open formats allow easy data reuse.
Start with minimal overhead. NextPSA grows with your model complexity and helps ensure quality from the beginning.
Feedback from our first testers helps shape NextPSA into the most accessible PSA modeling platform.
