System Check (Inteliweb)

Half of ComfyUI troubleshooting starts with a version question: "what ComfyUI, what Python, what GPU, how much VRAM?" And half of the answers people give are guesses. System Check turns that into a button: one node that dumps your whole environment - ComfyUI and frontend versions, Inteliweb Nodes version, Python, OS, CPU, RAM, PyTorch, CUDA/ROCm runtime, detected GPU, VRAM, and the installed versions of the usual AI libraries - with a button to copy it all for pasting into a help thread or issue.

How it works

It's a frontend-driven output node with no inputs and no outputs. The backend collects everything through boring, reliable channels: distribution metadata for the ComfyUI version (via importlib.metadata), platform for OS/CPU, module version attributes for PyTorch and friends, and the same collect_resource_status() the pack's Resource Monitor uses for RAM/VRAM. That shared source matters: it's what lets the pack report container RAM correctly via cgroups on Linux (RunPod, Vast) and fall back to psutil on Windows - the README notes it was validated on RunPod, Vast AI, and Windows Pinokio, which is a wider compatibility claim than most diagnostic nodes bother making. The three buttons are run diagnosis, free memory (it reuses the Free Memory cleanup), and copy info.

Why you'd reach for it

Two reasons. First, your own debugging: when a workflow OOMs or a sampler misbehaves, having the exact ComfyUI + PyTorch + CUDA versions on screen beats hunting through python -c incantations. Second, and this is where it really pays for itself, community support: the quality of help you get in a reddit thread or a GitHub issue goes way up when you paste a complete, unambiguous system report instead of "i have a 4060 i think". It's the ComfyUI equivalent of nvidia-smi plus pip list in one click.

Installing it

Part of the Inteliweb pack:

cd ComfyUI/custom_nodes
git clone https://github.com/maoper11/comfyui_inteliweb_nodes.git
cd comfyui_inteliweb_nodes
python -m pip install -r requirements.txt

Or ComfyUI Manager → "ComfyUI_Inteliweb_nodes". Dependencies: psutil and nvidia-ml-py (the latter gives full NVIDIA metrics when present). No model downloads, restart ComfyUI.

Honest caveats

It's a frontend node, so if the panel doesn't render you're looking at a Classic-vs-Nodes-2.0 issue or a stale pack - the diagnostic content is all collected server-side, but the display is JavaScript. Version detection can report "Not installed" for distributions ComfyUI was installed from outside pip, which is a display quirk, not a broken install. And if you already run Crystools or another monitor that covers this, System Check is redundant - it's a nicety, not a necessity. But for "quick, what's your setup?" it's the fastest honest answer in the pack.
