ThingsBoard’s drag-and-drop dashboard builder creates live multi-tenant data visualisation widgets without writing frontend code, enabling deployment of customer-facing dashboards in hours. Rule Engine visual flow builder configures event-driven automation — trigger alarms, enrich telemetry with device metadata, forward to external systems — without programming, using a functional reactive pipeline model. Multi-tenancy with white-labelling allows IoT solution providers to offer branded portals to end customers while sharing a single infrastructure. Edge computing with ThingsBoard Edge deploys rule chains and local dashboards on gateway hardware with bidirectional sync to the cloud. REST and WebSocket APIs provide full programmatic access for integration with ERP, SCADA, and BI tools.
