Your machine – live in the browser. realvirtual WEB is the browser platform for the whole machine lifecycle: import CAD, define kinematics and size drives (beta) in the editor, plan layouts and simulate material flow, commission virtually against the real PLC through realvirtual CONNECT, then hand the same file over as a live 3D HMI and machine information system. Operators see drive positions, sensor readings, alarms and KPIs where they happen, not on a flat panel. Technicians click a part and get documentation, live status and signal history on any device, without installing anything. One GLB carries it all – from sales presentation to virtual commissioning to running operation.
What it does
One platform – editor, planning, simulation and virtual commissioning for engineering, Digital Twin Viewer for sales, 3D HMI for operations, Machine Information System for service. All browser-based.
CAD Import & Editor
Import STEP, JT, USD and FBX directly in the browser – no Unity, no conversion step, no upload: the geometry is tessellated locally on your own machine. A JT brings its kinematics along from a PLMXML file (Siemens NX, Teamcenter) – joints, limits and gear couplers become movable axes. In the editor you set pivots, group parts, assign materials and build kinematics; a re-import updates a CAD revision in place. Part of the commercial license.
Virtual Commissioning
Test the PLC program against the simulated machine before the hardware exists: realvirtual CONNECT links the browser model to Siemens S7, Beckhoff TwinCAT, OPC UA and more, and drives, sensors and LogicSteps respond to the real controller's signals at 60 Hz. The same model then goes on to become the 3D HMI.
Live 3D HMI
Replace desktop HMI applications with a browser link. Real-time PLC signal visualization via WebSocket. Drive monitoring, sensor states, KPI overlays, alarm dashboards, and production charts powered by Apache ECharts. Faster fault diagnosis, better situational awareness.
Machine Information System
Attach documents, maintenance guides, spare part lists, and manuals directly to 3D components. Technicians click a part and see its documentation in context. The EU Machinery Regulation 2023/1230 (effective January 2027) now enables fully digital machine documentation – realvirtual WEB is ready.
Transport Simulation
Full in-browser simulation at 60 Hz: conveyor surfaces, sources, sinks, sensors with collision, grippers, and material flow.
LogicStep Sequencing
Serial/parallel containers, signal conditions, delays, drive commands – compatible with realvirtual.io Professional. Use it for interactive sales demonstrators or step-by-step maintenance instructions.
WebXR (VR/AR)
Runs on all AR and XR devices out of the box – Meta Quest, Apple Vision Pro, HTC Vive, Android/iOS AR – without native builds, app-store submissions, or device-specific compilation. One URL works everywhere.
Browser does not mean cloud
realvirtual WEB is a static web application: the browser loads the application once – and you decide from where. Machine data takes a different path: it flows directly between browser and machine inside your local network. There is no cloud backend, no account and no lock-in – the source code is open, and so is the GLB format.
From editing to 3D HMI – in the browser
realvirtual WEB grows beyond delivery: build kinematics in the editor, plan layouts, simulate material flow, commission virtually against the real PLC, and run the same model as a 3D HMI and machine information system – right in the browser.
CAD import & editor
Import STEP, JT, USD or FBX straight into the browser and build the mechanism there: set pivots, group parts, assign joints and drives – a delta robot's axis arms become movable kinematics without leaving the page. A re-import updates a CAD revision in place. Part of the commercial license.
Layout planning
Assemble plant layouts from library components – in the browser, no installation. Built for sales teams: give your customers planning transparency with a single link. And with a Commercial license, white-label the planner into your own product.

Discrete event simulation (DES) Beta
Simulate material flow and analyze throughput and cycle times – the simulation engine runs locally in the browser, your data stays with you.
Virtual commissioning and live data via realvirtual CONNECT
Connect the simulated machine to the real controller and test the PLC program in the browser. CONNECT links WEB to real controllers: Siemens S7, Beckhoff TwinCAT ADS, OPC UA, MQTT, Modbus, EtherNet/IP, Bosch ctrlX, Keba, FANUC, Denso and more – for live 3D HMI and monitoring on the running machine.
AI error diagnosis with your own manuals
A PLC fault signal, one click on “Ask AI” – and the operator sees cause and remedy, written from your own machine documentation, with a link to the exact PDF page.
RAG instead of guessing
Your manuals are indexed locally into a vector database. On an alarm, the search finds the matching passages first – only then does the language model write the answer, anchored in your real documents. The source reference opens the PDF at the cited page.
LLM freely selectable
Connected via the OpenAI-standard interface: an EU-hosted provider for data sovereignty, or a fully local model on your own hardware – pure backend configuration, no viewer update.
Your documentation stays on site
PDFs, search index, and embeddings live on your CONNECT backend. Only short text excerpts reach the model; the API key never reaches the browser. Operator comments are stored centrally and shared across shifts and devices.
AI-First Approach
realvirtual WEB is fully AI-enabled through the Model Context Protocol (MCP). AI assistants can design, build, test, and debug digital twins end-to-end.
MCP Server Integration
The realvirtual MCP Server connects AI assistants to the running browser scene – list drives, read/write PLC signals, query the scene hierarchy, inspect sensor states, and automate testing through natural language.
Claude Code Ready
realvirtual WEB includes a full Claude Code setup: CLAUDE.md with architecture guidelines, slash commands for common workflows (/dev, /debug, /test, /build), and MCP tools reference. Prompt your Web Digital Twin.
Built for industrial reality
Sales & Product Presentation
