Unity Verified Solution Partner“Digital Twin” means everything and nothing. What matters is what you do with it – visualize machines for sales, run plant simulation before building, test PLC code without hardware, or monitor live production in 3D. realvirtual is the industrial 3D simulation platform that covers all of it – in the browser when the twin has to travel, in Unity when you are building an application, on one core and one open format.
One Simulation Platform – Many Use Cases
Sales & Visualization
Present machines interactively in 3D before they're built. Let customers explore, configure variants, and experience your automation solution live – on desktop, tablet, VR headset, or directly in the browser. Far more convincing than slides, far more accessible than installed software. Shorten your sales cycle and win projects with high-end 3D visualization.
Robot & Plant Simulation
Validate collision paths, measure cycle times, and prove feasibility – all in a behavior-accurate plant simulation with real drive and sensor logic, not just keyframe animation. Whether it's conveyor systems, AGVs, or complex multi-axis machines: catch problems in the planning phase before they cost real money on the shop floor.
Virtual Commissioning
Connect real PLCs (Siemens, Beckhoff, Rockwell) and robot controllers (ABB, KUKA, Universal Robots, Fanuc) to the digital twin. Virtual commissioning software that lets you test and ramp up automation code before hardware ships. Reduce on-site commissioning time by up to 75%, improve software quality, and eliminate costly last-minute fixes.
AI Training
Generate large-scale synthetic training data for industrial vision systems – object detection, classification, segmentation, and pose estimation. Train YOLO-based models with one click, test them in the running digital twin, and deploy as standard ONNX models. Your digital twin becomes the data factory for industrial AI.
3D Machine Information System
An interactive 3D machine information system connected to real PLCs via WebSocket and realvirtual CONNECT. Real-time machine status, sensor readings, KPI dashboards, and error management – all in 3D context. Link PDF documents, maintenance guides, and datasheets directly to machine components. Browse signal values live, trace error sources visually, and access documentation exactly where it's needed. Replace traditional 2D HMI with a spatial experience that operators, service technicians, and managers actually understand.
Open in the browser, local on your side
Build and share your digital twin in the browser: import CAD, set up kinematics, size drives and run the simulation in the editor, connect the PLC through CONNECT (beta), and hand the same model to customers, operators and service technicians through a single link — then extend it with the web frameworks your team already uses.
Fully Local & Private
Host on your own infrastructure or any CDN, without a mandatory cloud account and without being tied to us. Sensitive machine data, production layouts, and IP never leave your network. The 3D rendering runs on the device itself, so there is no GPU farm and no streaming infrastructure to operate.
One Link, Any Device
Desktop, tablet, smartphone, VR headset – WebGL, WebGPU, and WebXR supported out of the box. True cross-platform without app stores.
Your customer opens the digital twin in any browser – local, free, no license, no account.
Simulation studies, machine documentation, and 3D models travel freely to their recipients. Everything runs locally in the browser – your machine data stays with you. Viewing never needs a license, and nothing is tied to our cloud.
Developed in Germany – open in code, open to new technology.
How open, exactlyBuild in the browser. Use it everywhere.
Create and edit your digital twin directly in the browser. realvirtual is also available as a Unity plugin when you want to work in the Unity Editor. Use the same model for sales, commissioning, training and service, and deliver it with your machine as an interactive machine information system.
Import & Build
In the browser editor, import CAD data with realvirtual Commercial, define kinematics, and add drives and sensors. For Unity Editor projects, realvirtual is also available as a plugin.
Simulate & Commission
Size drives and check machine sequences. Material-flow studies (DES, beta) and PLC connection through CONNECT (beta) extend engineering in the browser, allowing tests before hardware ships.
Hand over as GLB
Whether built in the browser editor or in Unity, the twin is one GLB file – geometry, kinematics, signal bindings and all metadata included. Built once, opened anywhere.
Share a Link
realvirtual loads the GLB in the browser. Operators, customers, and service teams interact with the live digital twin – no installation needed.
Also available as a Unity plugin
Engineering can be done directly in the browser. For projects using C#, PhysX, XR builds and 25+ native controller interfaces, realvirtual is also available as a Unity Editor plugin: realvirtual Unity Starter (free) and realvirtual Unity Professional. Both paths – Unity and browser-based – use the same component model and GLB as their shared exchange format.
Build Once, Deploy Everywhere
One project compiles to Windows, Linux, macOS, WebGL, iOS, Android, Meta Quest, HoloLens, Apple Vision Pro. Deliver the digital twin with every machine you sell – as a 3D experience your customers actually use. With realvirtual you share it in any browser – viewing never needs a license.
No lock-in: it compiles without us
Complete C# source code, the AGPL-licensed browser platform on GitHub, GLB as an open exchange format. Your twin stays yours – even if we disappeared tomorrow. Extend, customize, and integrate without artificial restrictions.
Real-Time Performance
Real-time physics, high-fidelity rendering, and 60fps performance – even for complex machines with thousands of parts.
Massive Ecosystem
Access thousands of Unity packages, assets, and plugins. VR/AR, AI (Sentis), physics (PhysX, Algoryx), and more – ready to integrate.
realvirtual Commercial includes the realvirtual Unity Starter and Professional plugins as downloads — an option, not a prerequisite: the digital twin is authored in the browser, so Unity is not required. realvirtual Unity Professional is also available separately, without realvirtual Commercial. The Unity Editor licence is not included and must be obtained separately from Unity Technologies.
AI-Native Simulation Platform
Control, build, and debug your digital twin in plain language – from Claude, Cursor, or GitHub Copilot. The open-source MCP Server with 150+ tools connects AI agents live to realvirtual in the browser and to the Unity Editor – public on GitHub, verifiable, extensible.
MCP Server
150+ built-in tools let AI agents control realvirtual in the browser and in the Unity Editor in real time – navigate the scene, drive actuators, read sensors, write PLC signals, and automate testing. Open source and extensible.
Prompt Your Digital Twin
Ask your AI coding agent to add a conveyor, connect a PLC signal, debug a sensor, or generate a test sequence – in plain language. The MCP Server connects to realvirtual in the browser and to realvirtual Unity in the Editor. Your digital twin responds in real time.

What Our Customers Say
Real voices – from the Unity Asset Store and from industry projects
"We are building our MIS on realvirtual.io. Decision was driven by its architecture: a Unity-based authoring and virtual commissioning environment, self-hosted web runtime, and structured metadata across the machine lifecycle – a combo hard to find."
"As a PLC programmer I'm using RV Professional now since over 1 year and I love this all-in-one-solution to create machine simulations and easily connect to PLC for virtual commissioning. It can get quite complex but you will get great support by the RV team."
"Unity’s open ecosystem makes virtual commissioning scalable. High-fidelity visualization, CAD integration, and real-time physics, helps us create realistic digital twins to optimize automation, enabling faster, safer, more efficient commissioning."
"My goal has been to rebuild a full line developed in Process Simulate – a car manufacturing line for body in white, including tooling tables, robots, weld guns and material handling. My first impression of realvirtual is that it is super intuitive – the base information found online is more than enough to get someone rolling on a project. And it is open source: any issues you face can be sent to the forums or even to the developers."
"The whole package! This is really everything I needed to start my virtual 3D commissioning. From the capabilities of connecting many interfaces including my favorite: OPCUA, to the easy to set up drives, conveyors, robot arms and more!"
"I started with free package some time ago and I was amazed with functionality. I purchased pro version last year and built few projects for custom machines, mainly for conveyor systems. And it is not only tool for emulation. It runs in Unity where you can easily convert your project for example into VR presentation to show it to your customers or for training purposes. Great job!"
"I was able to design a prototype for my DT in just a few hours, the quality was good and the documentation helped a lot! I'm using the free version for now but it's a very good experience so far."
"We purchased RealVirtual.IO Professional for virtual commissioning and Digital Twin development of manufacturing machines. It is a really great tool for vendor-neutral development in a lightweight modeling environment. Moreover, we have had great support, and the how-to videos are really great too!"
"Connecting to my Siemens S7 was a breeze – got it up and running in minutes. The Interfaces, Drives, and Sensors concept is intuitive and feels really well thought out. Plus, everything is open source, which is a game-changer."
