In newer ComfyUI versions on RunComfy (for example the ComfyUI-Minimal v0.43.0 workflow), ComfyUI-Manager no longer has its own Manager button. It now opens from the Extensions button. Everything inside ComfyUI-Manager works the same as before: Install Missing Custom Nodes, the Custom Nodes Manager, Install via Git URL, the Model Manager and Restart are all still there.
1. Click the Extensions button in the top-right toolbar
When ComfyUI has finished loading, look at the toolbar in the top-right corner of the canvas, next to the Run button. Click the icon to the right of 0 active.
When you hover over it, the tooltip says Extensions.
2. Use ComfyUI-Manager as before
The ComfyUI-Manager window opens. From here you can install missing custom nodes, manage custom nodes and models, install via Git URL, update, or restart ComfyUI.
Another way: the ComfyUI menu
You can also click the ComfyUI logo in the top-left corner and choose Extensions. It opens the same ComfyUI-Manager window.
💡 Tip: If your workflow uses an older ComfyUI version and you see a Manager button in the top bar, keep using that button as before.
