Our verdict on ScadaBR
ScadaBR is an open-source supervisory control and data acquisition platform for monitoring and controlling industrial processes. Its browser-based operator interface, data-point acquisition, alarms and historical process views suit small teams looking for a free SCADA system they can run on their own infrastructure. It is also positioned for telemetry and plant-monitoring use cases, with scripting-oriented extensibility for adapting the software to industrial workflows.
The feature set covers core monitoring needs: industrial data-point acquisition, alarm configuration and event handling, historical data with trend visualization, and user-configurable dashboards and graphical views. Protocol support includes Modbus, OPC DA, DNP3 and BACnet, which gives ScadaBR a stated role across multiple industrial communication environments. The web client means operators can access the interface through a browser, while deployment remains on-premises and self-hosted. Teams should account for managing that infrastructure themselves rather than expecting a vendor-hosted service.
ScadaBR is distributed as a community project rather than a subscription service, and its open-source status makes it a fit for teams seeking a free starting point rather than a paid-plan comparison. Support channels are community resources and documentation, so organizations that need a defined commercial support arrangement should weigh that against their operational requirements. The published details do not establish redundancy, which matters for plants that require verified failover. Small teams prioritizing browser-based visibility, alarms, history and protocol coverage may find the scope relevant; buyers who need vendor-backed support or confirmed redundancy should consider alternatives that explicitly provide those assurances.
