comfy-model-vault 0.3.0

Find unused models and broken LoRAs in your ComfyUI install.

comfy-vault

Find unused models and broken LoRAs in your ComfyUI install.

comfy-vault is a standalone CLI that indexes your models/ tree (including nested subfolders), reads your workflow files to see which models you actually use, and reports the ones nothing references — so you can reclaim disk space without guessing. It does not need to run inside ComfyUI.

Install

pip install comfy-model-vault

The PyPI distribution is comfy-model-vault (the shorter name was already taken); it installs the comfy-vault command and the comfy_vault package.

Python 3.10+. The only runtime dependencies are click, pydantic and pyyaml.

Quickstart

# Index every model under a directory, recursively
comfy-vault scan /path/to/ComfyUI/models

# List models that no workflow references
comfy-vault orphans /path/to/ComfyUI/models \
  --workflows /path/to/ComfyUI/user/default/workflows

orphans is read-only. To actually remove the files, add --delete (it shows what it will do and asks for confirmation first; --yes skips the prompt):

comfy-vault orphans ./models --workflows ./workflows --delete

If your models live in several places, point comfy-vault at your extra_model_paths.yaml and it scans every declared root:

comfy-vault scan --extra-paths /path/to/extra_model_paths.yaml

Find byte-identical duplicates, hash files the way Civitai does, back-fill Civitai metadata by hash, or pre-flight free space before a download:

comfy-vault duplicates ./models                 # same-SHA256 copies
comfy-vault hash ./models --cache .vault.json   # SHA256 + Civitai AutoV2
comfy-vault civitai ./models --fixtures ./recorded   # offline metadata back-fill
comfy-vault space /mnt/nas/models --need 6GB    # will the next download fit?

Why

These are real, currently-open behaviours in ComfyUI and its ecosystem that make manual model cleanup error-prone. comfy-vault works around them from the outside:

• Models in subfolders are easy to lose track of (ComfyUI #10711). The scanner walks every level, not just the category root.
• extra_model_paths.yaml parsing is fragile and can throw on non-string values (ComfyUI #11404, PR #6441 closed unmerged). comfy-vault's parser skips reserved keys and bad values instead of crashing.
• Symlinks and junctions break on update, especially on Windows (ComfyUI #7662, #4412). comfy-vault reads canonical paths and never relies on ComfyUI-managed links.

There is no widely-used standalone orphan detector for ComfyUI today, which is the gap this fills.

Comparison

comfy-vault is not a replacement for the model managers — it does one thing they don't, and skips the things they do well.

	comfy-vault	ComfyUI-Manager	ComfyUI-Lora-Manager
Runs without ComfyUI	yes	no (extension)	no (extension)
Recursive subfolder scan	yes	partial	yes
Orphan detection from workflows	yes	no	no
Duplicate detection (content hash)	yes	no	metadata-based
Civitai metadata back-fill (by hash)	yes	no	yes
Download / install models	no	yes	yes
In-ComfyUI UI	no	yes	yes

If you want to download models or manage them inside the ComfyUI web UI, use the managers above. Use comfy-vault when you want to find and remove what you no longer need, or to audit a large library from a script or a backup host.

How orphan detection decides

A model is an orphan when no scanned workflow references its filename. Reference extraction is intentionally greedy: any string in a workflow JSON that ends in a known model extension counts as "in use", across both the UI and API workflow formats and any custom node. Because --delete removes files, comfy-vault errs toward keeping a model rather than risk flagging one that is actually used. Deletion is also confined to files inside the directories you scanned.

How duplicate detection avoids false positives

comfy-vault duplicates groups files only by their full SHA256, so two files are duplicates iff their bytes are identical. Four distinct LoRAs that share a name or a Civitai model are never grouped, because their content differs — which is exactly the false positive reported in Lora-Manager #841, where weaker matching flagged four different Qwen LoRAs as duplicates.

Web UI

For a read-only browser view, install the web extra and run the server:

pip install "comfy-model-vault[web]"
comfy-vault serve --models-dir /path/to/ComfyUI/models \
  --workflows /path/to/ComfyUI/user/default/workflows

It serves on http://127.0.0.1:8200 (FastAPI + HTMX, no JS framework) with an overview, the orphan and duplicate lists, base-model mismatch warnings, and a Civitai version browser. The base-model warnings flag LoRAs whose Civitai base model is not covered by any installed checkpoint; the version browser lists every Civitai version of a model and marks which are installed (Lora-Manager #778).
