🌌 ComfyUI UmeAiRT Toolkit

CI Docs

A Block-Based, Pipeline-Driven Toolkit for ComfyUI.

Stop fighting with "noodle soup"! The UmeAiRT Toolkit uses a hub-and-spoke architecture where typed bundles flow through a clean pipeline — from model loading to post-processing — with full interoperability with native ComfyUI nodes.

Workflow Example

✨ Key Features

🧱 Block Architecture (Hub-and-Spoke)

  • Typed Bundles: Loaders output UME_BUNDLE (model+clip+vae), settings output UME_SETTINGS, and the sampler creates a UME_PIPELINE that flows through the entire post-processing chain
  • GenerationContext: A single gen_pipe object carries models, settings, prompts, and the generated image — no global state, no race conditions
  • Direct Prompting: Connect Positive/Negative prompt editors directly to the Block Sampler

🔄 Full Interoperability (Pack/Unpack)

  • Pack Models Bundle: Use any native or community loader → pack into UME_BUNDLE → feed the Block Sampler
  • Unpack Pipeline: Extract IMAGE, MODEL, CLIP, VAE, prompts, settings from UME_PIPELINE → connect to any native node
  • Unpack Nodes: Decompose any UME bundle type into standard ComfyUI types

🎨 Custom Colors & UI

  • Automatic Connection Colors: Custom colors for UME types are injected into any active ComfyUI theme
  • Intelligent Resizing: Prompt nodes maintain readable sizes in Nodes 2.0
  • Color-Coded Categories:
    • 🔵 Blue: Model Loaders
    • 🟢 Green: Prompts
    • 🟤 Amber: Settings & ControlNet
    • 🟣 Violet: LoRAs
    • ⬛ Gray: Sampler
    • 🔵 Teal: Post-Processing

📦 Nodes Overview

Block Nodes (Core Pipeline)

| Category | Node | Description | |:---|:---|:---| | Models | Model Loader | Checkpoint loader → UME_BUNDLE | | Models | Model Loader - FLUX | UNET + Dual CLIP + VAE → UME_BUNDLE | | Models | 📦 Bundle Auto-Loader | Select category + version, auto-download & load (aria2 accelerated) | | Settings | Generation Settings | Width, Height, Steps, CFG, Seed → UME_SETTINGS | | Prompts | Positive / Negative Prompt Input | Multiline text editors with dynamic prompts | | LoRA | LoRA 1x/3x/5x/10x | Stackable LoRA loaders → UME_LORA_STACK | | Image | Image Loader | Load and prepare source images → UME_IMAGE (bundle only) | | Image | Image Process | All-in-one: set mode, denoise, resize, outpaint → UME_IMAGE | | Image | Image Process (Img2Img) | Dedicated img2img: denoise + auto-resize → UME_IMAGE | | Image | Image Process (Inpaint) | Dedicated inpaint: denoise + mask_blur → UME_IMAGE | | Image | Image Process (Outpaint) | Target dimensions + alignment → UME_IMAGE (KSampler executes) | | Sampler | KSampler | Central hub — receives all bundles, handles outpaint → UME_PIPELINE |

Post-Processing (Pipeline-Aware)

| Node | Description | |:---|:---| | UltimateSD Upscale / (Advanced) | Tiled upscaling with pipeline context | | SeedVR2 Upscale / (Advanced) | AI upscaler (bundled) | | FaceDetailer / (Advanced) | Face enhancement with BBOX detection | | Detailer Daemon / (Advanced) | Advanced detail enhancement | | Image Saver | Save with metadata preservation |

Pack/Unpack (Interoperability)

| Node | Direction | Description | |:---|:---|:---| | Pack Models Bundle | Native → UME | MODEL + CLIP + VAE → UME_BUNDLE | | Unpack Pipeline | UME → Native | UME_PIPELINE → IMAGE + all 14 fields | | Unpack Models Bundle | UME → Native | UME_BUNDLE → MODEL, CLIP, VAE | | Unpack Image Bundle | UME → Native | UME_IMAGE → IMAGE, MASK, mode, denoise | | Unpack Settings | UME → Native | Extract individual settings values |

Utilities

| Node | Description | |:---|:---| | 💾 Bundle Model Downloader | Download model bundles from HuggingFace (aria2 accelerated, no VRAM load — ideal for RunPod/cloud) |

🚀 Installation

Option A: ComfyUI Manager (Recommended)

  1. Open ComfyUI Manager
  2. Search for UmeAiRT Toolkit
  3. Click Install

Option B: Manual Installation

cd ComfyUI/custom_nodes
git clone https://github.com/UmeAiRT/ComfyUI-UmeAiRT-Toolkit.git
pip install -r ComfyUI-UmeAiRT-Toolkit/requirements.txt

📜 Third-Party Code & Attribution

This toolkit bundles or adapts code from the following open-source projects. We are grateful to their authors.

| Component | Source | Author(s) | License | |:---|:---|:---|:---| | seedvr2_core/vendor/ | ComfyUI-SeedVR2_VideoUpscaler | numz | Apache-2.0 | | usdu_core/ | ComfyUI_UltimateSDUpscale | ssitu | GPL-3.0 | | image_saver_core/ | ComfyUI-Image-Saver | alexopus | MIT | | Detail Daemon logic | sd-webui-detail-daemon | muerrilla | MIT | | facedetailer_core/ | Inspired by ComfyUI-Impact-Pack | ltdrdata | GPL-3.0 | | vendor/comfyui_gguf/ | ComfyUI-GGUF | City96 | Apache-2.0 | | vendor/aria2/ | aria2 | Tatsuhiro Tsujikawa | GPL-2.0 |

🔒 Security

UmeAiRT Toolkit is audited for common vulnerabilities:

  • Path Traversal: Patched in Image Saver with a while loop sanitizer + os.path.abspath() validation against the output directory
  • HTTP Timeouts: All urlopen calls enforce timeout=30/60 to prevent hanging on unresponsive servers
  • Token Safety: HF tokens are read from environment/cache, never exposed in workflow JSON

🧪 Testing

177 unit tests with GitHub Actions CI on Python 3.10–3.14:

# Run all tests locally
python run_tests.py

# Run with coverage
coverage run --source=modules run_tests.py
coverage report -m --skip-covered

CI enforces a 40% coverage floor (--fail-under=40).

New nodes should include structural tests — copy tests/_template_node_test.py.
