Our verdict on Scada-LTS
Scada-LTS is an open-source SCADA platform for teams that need browser-based monitoring and control in industrial or building-automation deployments. Its operator interface brings data-point monitoring, graphical views, historical logging and alarm management into a web application. User and permission administration supports controlled access. The project is distributed through GitHub, and its listed plans and product scope make it a fit for small teams seeking a free, basic SCADA system rather than a hosted commercial service.
Deployment and acquisition shape the fit. Scada-LTS is intended for self-hosted installations, so the organization is responsible for deploying and maintaining the server. Protocol-based data acquisition is included, with Modbus the specified protocol. This suits teams whose equipment and workflows align with that scope and who can manage the application environment; organizations needing a broader verified protocol set should compare alternatives before choosing. The browser-based operator client supports access through a web interface, while the deployment model remains under the team's control.
Its core feature set covers routine SCADA needs: visualizing data points, recording historical values, handling alarms, and administering users and permissions. Support channels are community resources and documentation, which may suit teams comfortable managing open-source software but offer a different support model from a commercial service. Choose Scada-LTS when free, self-hosted web monitoring with logging and alarms is the priority and Modbus meets acquisition needs. Teams seeking a hosted service, vendor-provided support, or a wider stated protocol range should look elsewhere.
