It is recommended to add imnodes or ImNodeFlow.

imgui-node-editor
Has not been updated for several years.

Thank you for the suggestions!

I looked carefully at both libraries:

imnodes: This library is similar to imgui-node-editor, but it does not provide zooming and panning features. I think these features are important for a node editor.

ImNodeFlow: This is a very nice library with good zoom support. However, the API uses many C++ templates (like addNode<MyNodeType>()), which makes it very difficult to create Python bindings. The template-based design does not translate well to Python. It would require major changes to the library.

imgui-node-editor: You are right that the original repository has not been updated recently (last commit ~2 years ago on develop branch). However, I maintain an active fork with many improvements and bug fixes: See branch imgui_bundle on my fork

My fork includes:

Regular updates to stay compatible with latest ImGui
Bug fixes
Adaptations for Python bindings
Integration improvements for ImGui Bundle
For now, I will continue to use and maintain imgui-node-editor in ImGui Bundle. It provides the best balance of features (including zoom/pan) and Python compatibility.

If ImNodeFlow's author adds a more Python-friendly API in the future, I would be happy to reconsider it.

However, I think that imgui-node-editor is still a good choice.
