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.
