workflow_templates

This repo hosts the official ComfyUI workflow templates and subgraph blueprints.

Overview

Content	Description	Package
Workflow Templates	Full standalone workflows for the template picker	comfyui-workflow-templates
Subgraph Blueprints	Reusable node components that appear in the node palette	comfyui-subgraph-blueprints

The repository uses a package-per-media structure:

• packages/core – manifest + loader helpers shipped as comfyui-workflow-templates-core
• packages/media_* – workflow template JSON + preview assets for each media type
• packages/blueprints – subgraph blueprint JSON + preview assets as comfyui-subgraph-blueprints
• packages/meta and the root pyproject.toml – the comfyui-workflow-templates meta package

Quick Start

Task	Commands

Adding New Templates

I will demonstrate how to add a new template by walking through the process of adding the Wan text to video template.

1 — Find Templates Folder

Set up ComfyUI_frontend dev environment. In the ComfyUI_frontend/.env file, add the line DISABLE_TEMPLATES_PROXY=true then start the dev server with npm run dev.

Copy the templates folder from this repository to the ComfyUI_frontend/public folder.

2 — Obtain Workflow

Either

• Create the workflow and export using Save => Export
• Use an existing workflow. To extract the workflow json from an image, you can use this tool: https://comfyui-embedded-workflow-editor.vercel.app/

I will get my workflow from the ComfyUI_examples Wan 2.1 page. To get the workflow from the video on that page, I'll drag the video into comfyui-embedded-workflow-editor. Then I'll copy and paste it into a new json file on my computer.

Important

Make sure you start ComfyUI with --disable-all-custom-nodes when creating the workflow file (to prevent custom extensions adding metadata into the saved workflow file)

3 — Obtain Thumbnails

Ideally, the thumbnail is simply the output produced by the workflow on first execution. As an example, see the output of the Mixing ControlNets template:

For my Wan 2.1 template, I'll just use the webp video I got the workflow from.

4 — Choose Thumbnail Type

Choose the content type and hover effect (optional) for your thumbnail:

Content Types	Hover Effects
Image: Default image with no extra effect	Compare Slider: Before/after comparison tool
Video: Webp animation	Hover Dissolve: Dissolves to 2nd image on hover
Audio: Audio playback	Hover Zoom: Same as default but zooms more

Warning

For video thumbnails, thumbnails need to be converted to webp format first

Since my Wan 2.1 thumbnail is already an animated video, I'll use a video thumbnail but choose not to add an effect.

5 — Compress Assets

Attempt to compress the assets. Since the thumbnails will never be taking up a large portion of the screen, it is acceptable to lower their size. It's also good to convert them to a space-efficient file format like webp or jpeg, applying a lossy compression algorithm (e.g., convert at 65% quality).

EzGif has free tools for changing resolution, compressing, and converting file types. Use whatever tool you are comfortable with.

Tip

Convert to webp first, then resize to a smaller resolution. You can maintain high quality and still get near 95% reduction if e.g., converting from png.

6 — Rename and Move Files

Give the workflow a filename that has no spaces, dots, or special characters. Then rename the thumbnail file(s) to match, but with a counter suffix.

your_template_name.json
your_template_name-1.png
your_template_name-2.png

I'll name the Wan 2.1 template as text_to_video_wan.json. So my files will be:

text_to_video_wan.json
text_to_video_wan-1.webp

Then move the renamed files to your templates folder.

7 — Assign Bundle & Sync Assets

Each template lives in one bundle (media-image, media-video, etc.). Update bundles.json with the template ID so the correct media package ships it. After editing templates/ or bundles.json, regenerate the manifest and copy assets into the package directories:

python scripts/sync_bundles.py
# or via Nx  
npm run sync

This step must be run before committing; CI will fail if the manifest/bundles are out of sync.

8 — Add Entry to index.json

There's an index.json file in the templates folder which is where template configurations are set. You will need to add your template to this file, using the fields outlined below:

If your template doesn't fit into an existing category, you can add a new one:

  {
    "moduleName": "default",
    "title": "Basics",
    "type": "image",
    "templates": [
      {
        "name": "default",
        "mediaType": "image",
        "mediaSubtype": "webp",
        "description": "Generate images from text descriptions."
      },
    ]
  },
+ {
+   "moduleName": "default",
+   "title": "Your New Category"s Name",
+   "type": "video",
+   "templates": [
+     {
+       "name": "your_template_name",
+       "description": "A description of your template workflow",
+       "mediaType": "image",
+       "mediaSubtype": "webp",
+       "description": "Your template"s description.",
+       "tutorialUrl": "https://link-to-some-helpful-docs-if-they-exist.como"
+       "thumbnailVariant": "zoomHover",
+     },
+   ]
+ }

The Wan 2.1 template I'm adding already fits into the "Video" category, so I'll just add it there:

  {
    moduleName: "default",
    title: "Video",
    type: "video",
    templates: [
      {
        name: "ltxv_text_to_video",
        mediaType: "image",
        mediaSubtype: "webp",
        tutorialUrl: "https://comfyanonymous.github.io/ComfyUI_examples/ltxv/"
      },
+     {
+       "name": "text_to_video_wan",
+       "description": "Quickly Generate videos from text descriptions.",
+       "mediaType": "image",
+       "mediaSubtype": "webp",
+       "tutorialUrl": "https://comfyanonymous.github.io/ComfyUI_examples/wan/"
+     },
    ]
  },

The thumbnailVariant field is where you add the choice of thumbnail variant.

Now you can start ComfyUI (or refresh browser if already running) and test that your template works.

Warning

Make sure to use double-quotes " instead of single-quotes ' when adding things to json files

9 — Embed Models

Now we need to embed metadata for any models the template workflow uses. This way, the user can download and run the workflow without ever leaving ComfyUI.

For instance, my Wan 2.1 template requires 3 models:

• umt5_xxl_fp8_e4m3fn_scaled text encoder
• wan_2.1_vae VAE
• wan2.1_t2v_1.3B_bf16 model

To add them to the workflow json, find each associated node and add the metadata to their properties:

    {
      "id": 39,
      "type": "VAELoader",
      "pos": [866.3932495117188, 499.18597412109375],

      },
      "widgets_values": ["wan_2.1_vae.safetensors"]
    },

    {

      },
      "widgets_values": [
        "umt5_xxl_fp8_e4m3fn_scaled.safetensors",
        "wan",

      ]
    },

    {
      "id": 37,
      "type": "UNETLoader",
      "pos": [485.1220397949219, 57.094566345214844],

      "mode": 0,
      "inputs": [],
      "outputs": [
        {
          "name": "MODEL",
          "type": "MODEL",
          "links": [92],
          "slot_index": 0
        }
      ],
      "properties": {
        "Node name for S&R": "UNETLoader",
+       "models": [
+         {
+           "name": "wan2.1_t2v_1.3B_bf16.safetensors",
+           "url": "https://huggingface.co/Comfy-Org/Wan_2.1_ComfyUI_repackaged/resolve/main/split_files/diffusion_models/wan2.1_t2v_1.3B_bf16.safetensors?download=true",
+           "hash": "6f999b0d6cb9a72b3d98ac386ed96f57f8cecae13994a69232514ea4974ad5fd",

+       ]
      },
      "widgets_values": ["wan2.1_t2v_1.3B_bf16.safetensors", "default"]
    },

You can find the hash and hash_type for a model on huggingface (see below)or by calculating it yourself with a script or online tool.

Workflow spec and ModelFile Zod schema for more details.

Caution

Ensure that the filename being downloaded from the links matches the filenames in the widgets_values exactly.

10 — Embed Node Versions (optional)

If your template requires a specific version of Comfy or a custom node, you can specify that using the same process as with models.

The Wan 2.1 workflow requires the SaveWEBM node which wasn't fully supported until ComfyUI v0.3.26. I can add this information into the SaveWEBM node:

    {
      "id": 47,
      "type": "SaveWEBM",
      "pos": [2367.213134765625, 193.6114959716797],
      "size": [315, 130],
      "flags": {},
      "order": 9,
      "mode": 4,
      "inputs": [
        {
          "name": "images",
          "type": "IMAGE",
          "link": 93
        }
      ],
      "outputs": [],
      "properties": {
        "Node name for S&R": "SaveWEBM",
+       "cnr_id": "comfy-core",
+       "ver": "0.3.26"
      },
      "widgets_values": ["ComfyUI", "vp9", 24, 32]
    },

This can help diagnose issues when others run the workflow and ensure the workflow is more reproducible.

11 — Add Documentation Nodes (optional)

If your template corresponds with a page on https://github.com/comfyanonymous/ComfyUI_examples, https://docs.comfy.org/custom-nodes/workflow_templates, etc., you can add a MarkdownNote node with links:

Raw markdown used:

### Learn more about this workflow

> [Wan - ComfyUI_examples](https://comfyanonymous.github.io/ComfyUI_examples/wan/#text-to-video) — Overview
>
> [Wan 2.1 Tutorial - docs.comfy.org](https://docs.comfy.org/tutorials/video/wan/wan-video) — Explanation of concepts and step-by-step tutorial

12 — Sync Translations

Before creating your PR, sync your template to all language versions using the translation management script.

1. Run the translation sync script:

   python3 scripts/sync_i18n.py --templates-dir templates

2. The script will:

   • Auto-sync technical fields (models, date, size, etc.) to all language files
   • Detect untranslated title/description fields
   • Add your template to scripts/i18n.json for translation tracking
   • Generate language-specific template files (index.zh.json, index.ja.json, etc.)

3. (Optional) Add translations in scripts/i18n.json:

   {
     "templates": {
       "your_template_name": {
         "title": {
           "en": "Your Template Title",
           "zh": "您的模板标题"
         },
         "description": {
           "en": "Your template description",
           "zh": "您的模板描述"
         }
       }
     }
   }

4. Run sync again to apply your translations

For detailed instructions, see scripts/I18N_GUIDE.md.

13 — Create PR

1. Fully test the workflow: delete the models, input images, etc. and try it as a new user would. Ensure the process has no hiccups and you can generate the thumbnail image on the first execution (if applicable).
2. Verify all language files (index.zh.json, index.ja.json, etc.) are synced and committed
3. Create a fork of https://github.com/Comfy-Org/workflow_templates (or just checkout a new branch if you are a Comfy-Org collaborator)
4. Clone the fork to your system (if not a collaborator)
5. Copy your new workflow and thumbnail(s) into the templates folder
6. Add your changes to the templates/index.json file
7. Bump the version in the root pyproject.toml (example)
8. Commit and push changes
9. Create a PR on https://github.com/Comfy-Org/workflow_templates

Version bumping and package building are automated via CI/CD. Bumping the root pyproject.toml version automatically:

• Detects which subpackages have changed since their last release
• Bumps versions only for affected packages
• Updates all dependency references
• Builds and publishes packages to PyPI

Here is the PR I made for the Wan template: #16

Once the PR is merged, if you followed step 6 correctly, a new version will be published to the comfyui-workflow-templates PyPi package.

Adding New Blueprints

Subgraph Blueprints are reusable workflow components that appear as single nodes in ComfyUI. They use the native ComfyUI subgraph format.

For detailed documentation, see docs/BLUEPRINTS.md.

Quick Guide

Option 1: Import from External Source

1. Copy blueprint JSON files to blueprints/ directory
2. Run the import script to normalize names and generate metadata:

   python scripts/import_blueprints.py

3. Sync to packages:

   python scripts/sync_blueprints.py

Option 2: Create in ComfyUI

1. Build your workflow in ComfyUI
2. Select nodes → Right-click → "Create Subgraph"
3. Export the workflow JSON
4. Copy to blueprints/ with a snake_case filename (e.g., text_to_image_flux.json)
5. Run import and sync scripts

Blueprint File Structure

blueprints/
├── index.json                        # Generated metadata for UI
├── index.schema.json                 # Validation schema
├── text_to_image_flux_1_dev.json     # Blueprint (native ComfyUI subgraph format)
├── text_to_image_flux_1_dev-1.webp   # Thumbnail (optional)
└── ...

Blueprint JSON Format

Blueprints use the native ComfyUI subgraph format with definitions.subgraphs:

{
  "id": "workflow-uuid",
  "nodes": [{"id": -1, "type": "subgraph-uuid", ...}],
  "definitions": {
    "subgraphs": [{
      "id": "subgraph-uuid",
      "name": "Text to Image (Flux.1 Dev)",
      "inputs": [
        {"name": "text", "type": "STRING"},
        {"name": "width", "type": "INT"}
      ],
      "outputs": [
        {"name": "IMAGE", "type": "IMAGE"}
      ],
      "nodes": [...],
      "links": [...]
    }]
  }
}

Sync Commands

# Import and normalize external blueprints
python scripts/import_blueprints.py

# Generate manifest and sync to packages
python scripts/sync_blueprints.py

Create PR

1. Test the blueprint in ComfyUI
2. Ensure python scripts/sync_blueprints.py produces no changes
3. Bump version in root pyproject.toml
4. Create PR
