The main experience is the Kforge Labs sidebar. It helps you keep a project setup together: favorite nodes, saved workflows, reusable modules, tags, snapshots, and recovery tools.

Kforge Labs Sidebar

Use the sidebar as a reusable project kit.

| Feature | What it does | |---|---| | Snapshots | Save and load the whole Kforge Labs state: favorite nodes, workflows, modules, tags, archive, and recovery data. | | Search | Find nodes, workflows, directories, and tags from one field. Tags keep exact capitalization, so Depth and depth can be separate folders. | | Nodes | Keep favorite nodes close, grouped by theme or repository name. | | Workflows | Save the whole script, save a selection of nodes, load workflows, or insert saved modules into the current canvas. | | Recovery | Use autosaves, starter presets, snapshot library settings, and missing-pack install helpers. |

New here? Start with the KForge overview. Using it inside ComfyUI? Open the operational guide:

Browse on the web: malkuthro.github.io/ComfyUI-Koolook/web/guide/
Inside ComfyUI: Kforge Labs sidebar → Tools row → Help (H icon). The in-app button opens the bundled offline copy at web/guide/index.html.

The root Koolook nodes and the slim Radiance Koolook VAE wrappers have no extra Python dependencies beyond torch, which ComfyUI already requires. The video wrappers require Video Helper Suite, and the LTX Director fork is for workflows that already use the LTX / Prompt Relay node ecosystem. The Koolook Matte nodes additionally need diffusers (already pulled in by the LTX Director / Radiance forks) and use huggingface_hub to download the SVD + VideoMaMa model weights at runtime.

Install

ComfyUI-Manager

Open ComfyUI Manager.
Choose Install Custom Nodes.
Install by Git URL: https://github.com/malkuthro/ComfyUI-Koolook.git
Restart ComfyUI.
Open the Kforge Labs sidebar tab.

Manual

Clone this repository into ComfyUI/custom_nodes/:

git clone https://github.com/malkuthro/ComfyUI-Koolook.git

Restart ComfyUI after installation.

One install at a time. If you already installed Kforge Labs via ComfyUI Manager, it lives at custom_nodes/koolook/ (the Manager / Registry-derived folder name). A second custom_nodes/ComfyUI-Koolook/ created by git clone is a parallel install — ComfyUI loads BOTH on every boot, both register the same routes and sidebar tab, and the workflow store silently corrupts on every restart. From v0.3.8 the plugin detects this and prints a critical log naming both paths, disabling the non-winning copy — but the cleanest fix is to remove one folder. Pick the install method you want and stick with it.

Troubleshooting

| What you see | What it usually means | What to do | |---|---|---| | The Kforge Labs tab does not appear | ComfyUI needs a restart, or the extension did not load | Restart ComfyUI and check the terminal for [Koolook] messages. | | The Help guide does not open | The browser blocked the popup | Allow popups for the ComfyUI page, or open web/guide/index.html directly. | | Missing custom nodes after loading a workflow | One or more node packs used by that workflow are not installed | In Kforge Labs, use Tools → Install missing packs, or use ComfyUI Manager's Install Missing Custom Nodes flow. | | Snapshot save/load fails | The snapshot library path may be missing, read-only, or unavailable | Use Snapshot → Save to... or Load from... and choose a writable folder. | | A loaded snapshot looks older than expected | Named saves and auto-saves are intentionally separate | In Snapshot → Load, select the snapshot and check Recovery auto-saves for a newer periodic/pre-load recovery. |

Support

For reproducible bugs, open a GitHub issue. For the fastest answer, include your ComfyUI version, Koolook version, operating system, install method, terminal log, browser console errors, and steps to reproduce. See SUPPORT.md for the exact checklist.

If Koolook helps your ComfyUI work, you can support development on Ko-fi.

Stability

For production work, install a pinned release tag or commit instead of following a moving branch head. Node IDs are treated carefully so saved ComfyUI workflows continue to load across compatible updates.
