So what is it?

ComfyUI-ModelBrowser is an add-on for ComfyUI, a visual tool for building AI image generation workflows. Normally ComfyUI only lets you pick model files, such as checkpoints, LoRAs, or VAEs, from a set of predefined folders. This extension adds a browse button next to every model dropdown so you can pick a model file from anywhere on your computer instead. It works automatically with any node that has a model dropdown, whether built into ComfyUI or added by another custom node, by detecting dropdowns that list model files rather than requiring the author to name specific nodes. When you pick a file from outside the normal folders, the extension only remembers that location for the current server session by keeping it in memory. It does not write anything to ComfyUI's configuration files, so restarting ComfyUI forgets the extra location. Workflows saved using a model picked this way still open fine for other people who do not have the extension installed, they will simply see that the model is missing, the same as with any file they do not own. Installing it works like any other ComfyUI custom node. You can install it through the ComfyUI Manager by pasting the repository's Git URL, clone it directly into your custom_nodes folder with git, or download it as a ZIP file and extract it there. After installing, you restart ComfyUI and hard refresh the browser page so the new interface loads. No extra Python packages are required. The README notes a few limitations. The file browser looks at the filesystem of the machine running ComfyUI, so if you access ComfyUI remotely you are browsing that remote machine's files, which is where your models need to live anyway. It also warns that if a file with the same name already exists in the normal models folder, the original file takes priority, and you will see a warning if that happens. The project is released under the GPL-3.0 license, meaning it can be used, modified, and shared, but any modified version you distribute must remain open source under the same license.
