Devil Nodes

Devil Nodes

ComfyUI nodes by ComfyUIdev.

Favorite parks the graph on a spot you care about. Press its shortcut, or double-click the node, and the canvas pans and zooms so the node sits on a saved anchor. X and Y offsets nudge that spot. The move can cut, or ease in with a blur that clears when you arrive.

Workflow Helper is a shareable card saved inside the workflow. Queueing a prompt does not run it. You fill it in when you create or share a graph: how to use it, which models to download, which custom node packs it needs, and your links. On another machine the card shows which models and packs are already there, which are missing, and downloads a missing model into the matching ComfyUI models folder. Card, banner, and info tile are three ways to show that one card.

Favorite is frontend-only. It has no inputs, no outputs, and it does not run. Workflow Helper's download buttons talk to this ComfyUI in the background.

Install

Install Devil Nodes (devil-nodes) and restart ComfyUI.

ComfyUI-Manager

Open Manager, search for Devil Nodes, and install it from the Registry.

Registry CLI

comfy node install devil-nodes

Git

cd ComfyUI/custom_nodes
git clone https://github.com/ComfyUIdev/devil-nodes

The folder name ComfyUI loads is devil-nodes. No extra Python packages are required.

Favorite

In the node menu, open Devil Nodes and add Favorite.

| Widget | What it does | | --- | --- | | shortcut_key | Keys that jump to this Favorite. Click the widget, then press the combo (1, shift + b, and so on). A new node takes the next free key from 1-9, 0, then a-z. | | zoom | Canvas zoom after the jump. Range 0.5–2, default 1. | | anchor | Where the node sits in the viewport. Default top-left is 16 graph units in from the left and 40 from the top. | | X-Offset | Added to the anchor. Positive moves the node right on screen. Default 0. | | Y-Offset | Added to the anchor. Positive moves the node down on screen. Default 0. | | Animate move | Off by default: the view cuts to the anchor. On: the view eases there in about 380 ms. Blur peaks halfway and is gone when the move ends. | | Blur | Peak blur, in pixels, while Animate move is on. Default 18, range 0–48. 0 keeps the eased move with no blur. |

Anchors: top-left, top-center, top-right, center, bottom-left, bottom-center, bottom-right.

Offsets are graph units, the same space LiteGraph stores in ds.offset:

canvas offset = anchor base + X-Offset + Y-Offset

Widget values are saved on the node, so they come back with the workflow.

Shortcuts are ignored while you are typing in a field. If the Favorite sits in a subgraph you are not viewing, the shortcut opens that subgraph first, then pans.

Workflow Helper

Workflow Helper is a shareable card saved inside the workflow. Queueing a prompt does not run it. You fill it in when you create or share a workflow: how to use the graph, which models to download, which custom node packs it needs, and your links. Someone who opens that workflow on another machine can see which models and packs they already have, which are missing, and download a missing model into the matching ComfyUI models folder. Card, banner, and info tile are ways to show that same card, not separate nodes.

In the node menu, open Devil Nodes and add Workflow Helper.

The card is view-only until you click the pencil (or right-click the node and choose Edit Workflow Helper). The editor saves a title, a Markdown how-to, model rows, pack rows, and links. Card shows all of that on the node. Banner shows only the title, so the same node can label a stage or a column. Info tile is a compact button: an icon and the title. Click it to open the full card, including downloads.

The how-to field accepts pipe tables and [teal], [green], [amber], and [glow] tags with a matching closing tag. Fenced code shows those characters as typed.

| Section | What it stores | | --- | --- | | Title | The large heading. In the banner layout this is the whole card. | | How-to | Markdown: headings, lists, bold, italic, code, tables, and http(s) links. | | Models | File name, model folder (checkpoints, loras, vae, and the rest of this install), optional size and note, and a download URL. | | Node packs | Pack name, link, and one node class from that pack. If the class is registered here, the row is installed. | | Links | Label and http(s) URL for the author's pages. |

Model rows are grouped under models/<folder>. A dot marks each row: found, missing, or not checked (no folder, or this install has no such folder). Check again looks up ComfyUI's model list. Pack rows use the same installed / missing marks against the node classes this ComfyUI has loaded.

Scan workflow, in the editor or on the node's right-click menu, reads the loaders in this graph. It lists checkpoint, LoRA, VAE, diffusion, text encoder, ControlNet, embedding, upscale, and similar files that are not already on the card. Tick the ones you want and add them. The file name and folder are filled in. The download URL stays empty when the graph only has a local file name.

Download sends the row's URL, file name, and folder to this ComfyUI process. The file is written only inside a model directory ComfyUI already knows. Paths that would leave that directory are rejected. The button shows progress, then Installed, or the error and Retry.

URLs can be:

• a direct http or https link, including Civitai download links
• a Hugging Face file URL, or hf://org/repo/file.safetensors
• a pasted hf download hf://... command
• a b2: link, when rclone is on PATH

A Hugging Face token in the ComfyUI process (HF_TOKEN, HUGGING_FACE_HUB_TOKEN, or HUGGINGFACE_HUB_TOKEN) is sent only to Hugging Face hosts. CIVITAI_API_TOKEN (or CIVITAI_TOKEN) is sent only to Civitai hosts. Tokens are not printed in the progress line. b2: downloads need rclone configured the same way you already use it.

To use a gated Hugging Face model, set HF_TOKEN (or HUGGING_FACE_HUB_TOKEN) so the ComfyUI process can see it, or run hf auth login, then restart ComfyUI. When huggingface_hub is installed it picks up that login itself. If the library is missing and hf or huggingface-cli is on PATH, the download uses that command. Otherwise the file is fetched over HTTPS.

The card JSON is stored on the node, so it comes back with the workflow, including copy, paste, and the API format.

Requirements

• ComfyUI
• Python 3.8 or newer
• No extra Python packages. Workflow Helper uses aiohttp, which ComfyUI already provides. Hugging Face downloads use huggingface_hub when it is installed. If it is not, and hf or huggingface-cli is on PATH, that command is used. Otherwise the file is fetched over HTTPS. b2: links need rclone on PATH.

Nodes in this pack

| Node | Runs on | What it does | | --- | --- | --- | | Favorite | The browser only | Pans and zooms to a saved canvas anchor | | Workflow Helper | The browser, plus download routes on this ComfyUI | Shareable card: title, how-to, model downloads, pack checks, links |

More nodes can be added under py/ without changing how Favorite is loaded. See the layout below.
