One HMI. Every Screen.

Control Tomorrow, Today – with PlcVisu

PlcVisu is the industrial-grade visualization platform that redefines how engineers, integrators and automation teams design, brand and operate control systems.
Built for a world where PLC logic, edge scripts and cloud micro-services coexist, PlcVisu lets you build pixel-perfect HMIs and SCADA dashboards directly in the browser—visual-first, logic-connected, and relentlessly fast.

Drag. Drop. Dominate. Sketch an interface, bind live tags, and watch it light up simultaneously on a phone, a tablet, a 10″ panel and a command-room video wall—one project, four viewports, zero friction.

Whether your code runs in CODESYS, IEC 61131-3 runtimes, Node-RED, JavaScript, Python or anything in between, PlcVisu turns complex architectures into intuitive, interactive experiences—and evolves with you thanks to our rapid release cycle.


What makes PlcVisu different?

   
Logic & UI cleanly separated Keep ladder, ST or flow-code in the PLC; bind tags visually and iterate UIs in minutes—not days.
SVG-first design system Crisp, scalable graphics with global theme tokens for instant corporate branding—from mobile maintenance views to 8 K control walls.
Built for the browser Pure HTML5/JS runtime—no plug-ins, no installs. Runs on Linux, Windows, Android, iOS and headless edge devices.
Open by default Native bridges for OPC UA, MQTT, Modbus, REST and Web Sockets—talk to anything, anywhere, without vendor lock-in.
Industrial SCADA kernel inside Historization, alarms, trends, multilanguage UI and role-based security—all included, no extra licences.
Grows every day Weekly feature drops, public roadmap and an active community ensure your HMI keeps pace with tomorrow’s automation.

Design once. Deploy everywhere. From fieldbus to frontend, PlcVisu is the future of controlling and visualizing complex systems—whatever they run on, wherever they need to go.
