Operational simulation software

Test operational changes before they reach the real system.

Map how work moves through your system. Press Run to see where demand builds, queues grow, and staff get busy. Save each result so your team can compare what works.

Scenario comparison

Compare model versions and outcomes

Save a checkpoint before you change anything. Try a different staffing level, route, or rule, then compare the results or reopen an earlier version.

Saved results

Inspect and export simulation results

Open a saved run to see its totals, trends, and observations. Export the result data or reopen the model version and run configuration that produced it.

Saved hospital simulation results with summary totals, operational signal charts, and observation data.

Formats and runtimes

Simulation standards and portable artifacts

Import FMI models, exchange SSP system structures, run supported workloads in the browser, and package releases with SBOMs, digests, provenance, and verification records.

FMI 3

Import support

Import FMUs for Co-Simulation, Model Exchange, and Scheduled Execution.

SSP 2.0.1

Import + export

Import and export SSP system structures, component topology, and parameter sets.

CycloneDX 1.5

Release records

Generate SBOMs alongside artifact digests, build provenance, release attestations, and verification records.

WebAssembly

Browser runtime

Run supported simulation workloads locally in the browser through the packaged WebAssembly engine.

Data and messaging

Connectors for operational data and live systems

Use messaging transports for live inputs and outputs, tabular files for source data, and existing infrastructure for project storage.

Live-system messaging

Exchange simulation inputs and outputs with running systems and message brokers.

MQTT QoS 1
NATS JetStream
Apache Kafka
HTTP + webhooks
WebSocket

Project storage

Version projects in Git and persist hosted state in PostgreSQL and Cloudflare R2.

Project controls

Access control, audit history, and run provenance

Roles, identity events, project revisions, engine versions, and artifact digests record who changed a project and which version ran.

Role-based permissions

Assign owner, editor, and viewer permissions per project.

Durable audit trails

Record project and identity events in a queryable audit log.

OIDC identity

Authenticate with Google or Microsoft through OpenID Connect.

Run provenance

Store engine, project, model, and package identities with each run.

Artifact integrity

Record content digests, build provenance, and verification results for releases.

Local execution

Run supported models in the browser or a native runtime. Hosting is optional.
