Explore how NextPSA integrates intuitive design, computational accuracy, and cloud scalability to modernize probabilistic safety analysis workflows.
The Fault Tree Analysis Module 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 real‑time Preview Quantification feature delivers immediate, approximate analytical results, giving engineers rapid insight into reliability behavior before performing detailed computations.
The Event Tree Analysis Module is a user-friendly tool for constructing and analyzing event trees. It supports multiple branching scenarios, initiating events, intermediate events, and outcomes, enabling users to model system responses to various hazards effectively.
Integrated analytical tools evaluate event probabilities and outcomes, allowing engineers to assess risk propagation and understand complex system interactions.

The Analytical Results Dashboard offers a comprehensive visualization of cutsets, allowing users to interpret and analyze the results of fault and event tree analyses.
Interactive visualizations help identify critical failure paths and weak points within complex systems, improving traceability and risk communication.

NextPSA performs model checking to identify modeling errors and potential problems (warnings).
All checks are executed automatically and in real‑time after each modification, enabling early detection of model issues. Proactive error detection ensures data integrity, enhances model reliability, and supports accurate, validated safety assessments.
NextPSA provides a secure and scalable cloud repository where users can upload, organize, and manage models and analytical outputs within a centralized, controlled environment.
Built‑in collaboration tools enable controlled model sharing among engineering teams. Comprehensive version management tracks revisions, maintains historical integrity, and allows effortless rollback to previous baselines.
Traditional PSA software is often complex, expensive, and tailored for large enterprises. NextPSA delivers the same analytical rigor in a smart, accessible, and cost‑efficient cloud platform.
| 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| Offer overly complex, outdated UIs | ✅ Clean, modern, and focused interface |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 for research and affordable for industry |
| Limited collaboration and sharing options | ✅ Models and Results can be shared between users |
| Limited or no version management | ✅ Model versions can be created and restored |
| No automation of fault tree quantifications | 🚧 Automation planned in roadmap |
NextPSA is designed for engineering professionals and research teams seeking an efficient, intelligent, and technically robust approach to probabilistic safety modeling — without the complexity of legacy applications.
Ideal for teaching probabilistic safety concepts and conducting research in a flexible, standards‑compliant environment. Open data formats support transparency and reproducibility.
Optimized for small and mid‑size engineering projects where efficiency, collaboration, and rapid iteration are critical to success.
NextPSA is currently available in Beta. A free Academic plan and a Pro commercial plan are coming soon.

Find answers to common questions about using NextPSA during the beta phase and understanding its core capabilities.
Is software installation required?
No. NextPSA operates entirely in your browser — no installation, configuration, or local resources required.
What functionality is included in the beta release?
The beta release allows you to model fault and event trees, perform probabilistic quantification, and leverage cloud features such as model versioning and collaborative sharing. User feedback directly informs feature prioritization and roadmap development.
How is my data secured?
All communication is encrypted via SSL, and data is hosted on secure, EU‑based servers. Information is used solely for internal testing and continuous product improvement.
