A digital twin that updates in real time — and remembers.
IoT platforms are either time-series silos (good at storage, bad at relationships) or static asset models (good at relationships, can't react). Industrial operators need both. TwinGraph is both.
A plant floor has devices, machines, lines, operators, and sensors — and they all relate to each other. Historians store the data; asset models describe the hierarchy. Neither system talks to the other, and neither can react to a live event.
Every device, asset, machine, and operator becomes a live graph node. MQTT streams telemetry directly in via MQTTBrokerNode + MQTTTopicNode. Edges express topology — plant → line → cell → machine → sensor. History can be pushed to BigQuery for analytics. Agents run anomaly detection and trigger alarms via MCP or gRPC.
A few steps. Real infrastructure.
Model your plant
Plant, line, cell, machine, sensor — express topology as graph edges.
Stream telemetry
PLCs and sensors push to MQTT. TwinGraph ingests and persists every event.
Explore in Browser
TwinGraph Browser (Sigma.js) visualizes the live plant as a dense graph.
Agents watch
AI agents run anomaly detection on the graph and fire alarms over MCP.
Real industrial telemetry.

One system for topology and telemetry — no more time-series ↔ asset-model drift.

Real, running reference implementations for ISX15 engine and GEA CFL63 filler.
- 03
The Browser ships with the server — operators get a live view out of the box.
