A free, open-source industrial simulator that runs in your browser or as a desktop app. Build a conveyor system in 3D and drive it with IEC 61131-3 Structured Text or Ladder Diagram, a working subset of the languages real PLCs run.
Write your control logic in IEC 61131-3 Structured Text or draw it as Ladder Diagram rungs, a working subset of the standard languages industrial PLCs run, and it drives the line directly, one scan at a time.
.st file or PLCopen XML, ladder includedautStand builds systems like these on real plant floors. This runs them in a browser tab.
Conveyors, sensors, six-axis robots, and boxes simulated with a Jolt physics engine compiled to WebAssembly. Drag parts in from the catalog and press play.
Bind push-buttons, photo-eyes, diverters, and stack lights to your program by tag, and the running scan drives them as the line moves.
Free and open source. Fork it, self-host it, or run it offline with no account and no license to buy.
Browse the source →Share an invite link and edit the same line live with your team, or send a view-only link that shows the line without letting anyone change it.
Every part in the catalog is a package built on the Part SDK. Start your own in the browser, script its behavior with autocomplete, and download it as one file to share.
Press P and walk your line in first person, up the stairs and onto the platforms, or put on a headset and walk it in VR.
One project, two surfaces: pick whichever fits the job. Run it in a browser tab, or install the desktop app for real PLCs and hardware in the loop.
Nothing to install. Open a tab and start building.
The full engine on your machine, wired to real hardware.
No account, no download. Open the simulator and drop in your first conveyor.
