The hosted demo is temporarily offline while we roll out enhancements. Watch the walkthrough videos below, or contact us to schedule a live walkthrough in the meantime.

Watch the demo

See VectorMBE in action

A two-minute walkthrough of the platform: entity graphs, OWL reasoning, vector search, formal constraints, safety assessment generation, and architecture reasoning.

This walkthrough covers the core VectorMBE interface and workflows. Browse more focused demos below or contact us to request a topic.

Demo library

Focused demos by topic. More videos are on the way.

Platform overview

Two-minute tour of entity graphs, OWL reasoning, vector search, and safety assessment generation.

Hazard assessment generation

See VectorMBE synthesize hazard analyses, fault trees, and FMEA entries from a model graph.

VectorMBE

Try the Autonomous Systems Engineering Platform, No Build Required

Explore a hosted instance of VectorMBE. Query requirements, trace dependencies, validate coverage, generate complex safety assessments, and reason about architecture — all from your browser. VectorMBE goes far beyond requirements management: it autonomously synthesizes hazard analyses, derives architectural constraints, and evaluates design decisions against your safety case in real time.

What you'll see

A full VectorMBE instance, pre-seeded and ready

Entity graph

Browse a pre-loaded systems graph with nodes, edges, and OWL-classified entities. Inspect attributes, follow links, and visualize topology in 3D.

OWL reasoning

Run SPARQL-like queries over the ontology. Trace subclass relationships, check satisfiability, and see how formal axioms constrain the model.

Vector search

Search by meaning, not keyword. Vector embeddings rank similar designs, requirements, and telemetry by semantic proximity.

Formal constraints

Evaluate hard constraints that override probabilistic suggestions. See pass/fail results with severity levels and audit trails.

Safety assessment generation

Automatically synthesize hazard analyses, fault trees, and FMEA entries from your model graph. VectorMBE reasons over failure modes, propagation paths, and mitigation coverage to produce auditable safety artifacts.

Architecture reasoning

Ask architectural questions in natural language and receive answers grounded in your actual model. VectorMBE evaluates design decisions, surfaces constraint violations, and explains the rationale behind derived allocations and interface definitions.

Live demo

Temporarily offline for enhancements

Run locally

Prefer to run VectorMBE on your own machine? Build the Rust backend and the React UI from source.

Show terminal instructions
bash 
# Terminal 1 — start the backend
cd VectorMBE
export LD_LIBRARY_PATH="target/release/build/torch-sys-*/out/libtorch/libtorch/lib:$LD_LIBRARY_PATH"
VECTORMBE_REQUIRE_TORCH_GPU=false ./target/release/vectormbed

# Terminal 2 — start the UI
cd VectorMBE/ui
npm run dev

# Open the local UI in your browser

Requires Rust, Node 22, and a LibTorch setup. Or use Docker: docker-compose up --build in the VectorMBE repo.
