The editor
A tour of the OPC UA Modeler browser editor: live diagnostics, the diagram and documentation panels, saving, and the settings worth changing.
Generating with AI

Custom nodesets
Upload a vendor NodeSet2.xml to the browser editor and reference its types from your model with the imports block.
Running your model
Start a real OPC UA server exposing your model from the browser, and connect any OPC UA client to it.
Saving and sharing
Save models to your account, control whether they are private or public, and fork models from the community gallery.
