Key Features

Virtual Scrolling Engine: Seamlessly handles grid views with 10,000+ assets with zero UI lag.
Non-Blocking Indexing: Background scanning and metadata parsing (using worker threads) ensures the ComfyUI server remains responsive.
Database Optimization: SQLite WAL mode + Connection Pooling for high-concurrency access.

Advanced Visualization

GPU-Accelerated Video: WebGL-based video player for real-time grading (Exposure/Gamma/Zebra) of 4K content.
Viewer modes: single, A/B compare, side-by-side.
Navigation: zoom/pan, 1:1 pixel zoom, quick next/prev navigation.
Tools: exposure (EV), gamma, channel view (RGB/R/G/B/Alpha/Luma), analysis (false color, zebra).
Video Grading: Real-time color adjustments using WebGL (Hardware Accelerated).
Scopes (optional): downscaled RGB histogram + luma waveform.
Overlays: grid (thirds/center/safe/golden), pixel probe, loupe.
Compare: wipe (slider) and difference mode.
Export: save current frame to PNG + copy to clipboard (best-effort).

Metadata & Workflows

Extracts generation info from PNG/WEBP/video (ExifTool/FFprobe; degrades gracefully).
Recognizes modern workflows such as Qwen (Edit), Flux (Advanced/GGUF), WanVideo (Kijai), HunyuanVideo (Kijai), and Marigold (Depth).
Generation Info panel: prompt/model/sampling/image parameters + workflow minimap, with loading/error feedback and retry for transient failures.
Video: loops by default; player bar provides seek, In/Out range, loop/once, frame stepping, and FPS/step controls.

Search & Filtering

Full-text search powered by SQLite FTS5 (BM25 ranking).
Scope: Outputs, Inputs, Custom roots, Collections.
Filters: kind, min rating, workflow-only, date filters, sorting.
Optional: hide PNG siblings of video previews.
Summary line: total assets + selected count + current context.

Asset Management

Ratings/tags stored in the index DB and (optionally) synced into files when enabled.
Collections: create, add items (duplicates skipped and reported), remove items, open as a view. Large collections are capped for safety (configurable).
Context menu: tags, rating, add to collection, open in folder, rename, delete.

Drag & Drop

Drag an asset onto the ComfyUI canvas: stage to input, inject paths into compatible nodes.
Drag out to the OS (Explorer/Desktop): uses DownloadURL/text/uri-list and supports multi-selection ZIP (flat ZIP; folders excluded).

UX Details

Filename collision indicator: if multiple assets share the same filename, the extension badge shows EXT+ (e.g. PNG+).
Context menus: add/remove collection, open viewer, open in folder, copy path, etc.

Installation

Method A (Recommended): ComfyUI Manager

Install via the ComfyUI Manager UI.

Installing a specific version or nightly build

You can install a specific release tag or the nightly branch by using the GitHub ZIP archive URL. Example patterns:

Release tag (example):

https://github.com/MajoorWaldi/ComfyUI-Majoor-AssetsManager/archive/refs/tags/v2.3.2.zip
Nightly / latest main branch (example):

https://github.com/MajoorWaldi/ComfyUI-Majoor-AssetsManager/archive/refs/heads/main.zip

If your ComfyUI registry or manager accepts a zip URL, paste one of the above URLs to install that specific ref. The extension manifest includes a releases.zip_url_template that tools can use to programmatically construct these URLs; the template is:

https://github.com/MajoorWaldi/ComfyUI-Majoor-AssetsManager/archive/refs/{ref}.zip

Use {ref} = tags/vX.Y.Z for a tag, or {ref} = heads/<branch> (for example heads/main) for branch installs (nightly).

Method B: Manual Install

cd ComfyUI/custom_nodes
git clone https://github.com/MajoorWaldi/ComfyUI-Majoor-AssetsManager ComfyUI-Majoor-AssetsManager
pip install -r ComfyUI-Majoor-AssetsManager/requirements.txt

Restart ComfyUI.

If dependencies are missing at startup, install them explicitly:

python ComfyUI-Majoor-AssetsManager/scripts/install-requirements.py

No dependency installation is executed automatically at import time.

Required Python Packages

Runtime requirements are defined in requirements.txt:

aiohttp>=3.8.0
aiosqlite>=0.20.0
pillow>=11.0.0
send2trash>=1.8.0
watchdog>=3.0.0
pywin32>=300 (Windows only)

Install manually with one of:

pip install -r ComfyUI-Majoor-AssetsManager/requirements.txt

python ComfyUI-Majoor-AssetsManager/scripts/install-requirements.py

Tkinter Note (Embedded Python)

The native folder picker requires built-in tkinter. On embedded Python builds (for example python_embeded), tkinter is often missing, so the UI falls back to manual path entry.

The extension remains fully functional with manual path input.
pip install tk is not a replacement for built-in tkinter.
If you need the native folder picker, use a full Python installation with tkinter.

Optional (Recommended): ExifTool + FFprobe

The Assets Manager works without these tools, but metadata extraction (generation info, media probe) and tag/rating sync to files are best-effort and will be degraded if the tools are missing.

Verify they are available in your PATH:

exiftool -ver
ffprobe -version

If they are not in PATH, set MAJOOR_EXIFTOOL_PATH and/or MAJOOR_FFPROBE_PATH (see Environment Variables below).

Windows

Option A (Scoop):

scoop install ffmpeg exiftool

Option B (Chocolatey):

choco install -y ffmpeg exiftool

Option C (WinGet):

winget install -e --id Gyan.FFmpeg
winget install -e --id PhilHarvey.ExifTool

If the IDs differ on your machine, use winget search ffmpeg / winget search exiftool.

Option D (manual download):

FFprobe is included with FFmpeg builds: install FFmpeg and ensure the bin/ folder is in your PATH.
ExifTool: download from https://exiftool.org/ and point MAJOOR_EXIFTOOL_PATH to exiftool.exe if needed.

macOS

brew install ffmpeg exiftool

Linux

Debian/Ubuntu:

sudo apt-get update
sudo apt-get install -y ffmpeg exiftool

Package names can vary by distro (e.g. perl-Image-ExifTool on some).

Usage

Open the Assets Manager panel/tab.
Pick a scope (Outputs / Inputs / Custom / Collections).
Use search + filters; right-click cards for actions; double-click to open the viewer.
Use Collections to save sets of files and browse them later.
Drag assets:
- to the ComfyUI canvas (staging/inject path),
- or to your OS (single file or a ZIP for multi-selection).

Route Registration (Custom Nodes)

To avoid duplicate middleware/route injection, use explicit initialization with an aiohttp app:

from ComfyUI_Majoor_AssetsManager import init

def setup_with_app(app):
    init(app)

Auth-aware variant (recommended):

from ComfyUI_Majoor_AssetsManager import register

def setup_with_app(app, user_manager):
    register(app, user_manager=user_manager)

Notes:

register_routes(app) is idempotent per app instance.
No sys.modules replacement is required.
Do not call both manual registration and another auto-registration path for the same app.

API Namespace & Versioning

Extension endpoints are namespaced under /mjr/am/... to avoid collisions with ComfyUI native APIs (for example /api/assets/...).
Versioned compatibility path is supported via middleware redirect: /mjr/am/v1/... -> /mjr/am/... (HTTP 308).
During startup, the extension performs a route-collision check against existing app routes and logs overlaps if detected.

Hotkeys (high level)

Hotkeys are ignored while typing inside inputs.

Ctrl/Cmd+S: trigger an index scan for the current scope.
D: toggle details sidebar for the current selection.
0-5: set rating for the current selection (when interacting with the grid).
Viewer:
- Viewer hotkeys are consumed (do not leak to ComfyUI/global handlers).
- Esc: close viewer
- 0-5: set rating (single view)
- Shift+Arrow: step video frames (single video)
- F: false color toggle
- Z: zebra toggle
- G: grid cycle (off -> thirds -> center -> safe -> golden)
- I: pixel probe toggle
- L: loupe toggle
- C: copy last probed color hex
- Alt+1: toggle 1:1 zoom

Settings

Settings are stored under the mjrSettings key in localStorage (browser-side).

Backend persistence is currently limited to probeBackend.mode (stored in the SQLite metadata table). It uses a version bump so changes propagate quickly even with multiple backend instances. Other settings are intentionally browser-local and won't sync across machines/browsers.

Remote access & API Token (new):

The UI now exposes API token settings allowing administrators to configure a token and enable remote access to the Assets Manager. Access is disabled by default and the token is stored in the backend settings; ensure you secure your network if enabling remote access. See the user guide for configuration details.
Page size (assets per request)

Compatibility & CI

This project supports Python 3.10 through 3.12, with upstream ComfyUI guidance recommending Python 3.13 (3.12 as the stable fallback). GitHub Actions now runs both ci-python.yml and python-tests.yml on ubuntu-22.04 with actions/setup-python@v4 targeting Python 3.12 so the runner closely matches the ComfyUI best-practice environment.

ComfyUI compatibility baseline:

Minimum recommended ComfyUI: 0.13.0
Tested frontend baseline: 1.38.x
Older/development snapshots may break extension APIs; upgrade both ComfyUI backend and frontend together.

API reference:

Full endpoint table: docs/API_REFERENCE.md

Run tests across multiple Python versions locally with tox (requires those Python versions installed):

pip install tox
tox

Frontend compatibility notes:

UI classes/components are namespaced with mjr-am-* to reduce CSS/JS collisions.
ComfyUI frontend API access is centralized in js/app/comfyApiBridge.js (API, settings, sidebar registration) for legacy/new frontend compatibility.
i18n detection supports legacy and newer ComfyUI frontend locale surfaces, with fallback:
1. Stored Majoor language
2. ComfyUI locale settings/runtime
3. Browser/document locale
4. en-US
Majoor API endpoints are namespaced under /mjr/am/*.
Frontend bundle hygiene checks:
- npm run check:frontend-size
- npm run check:frontend-imports
Auto-scan (on open / on startup)
Status poll interval
Sidebar position (left/right)
Hide PNG siblings (video previews)
Sync rating/tags to files (best-effort; requires tools)
Media probe backend (auto/exiftool/ffprobe/both)
Observability (request logging)
Tags cache TTL (ms)
Workflow minimap display toggles

Environment Variables (backend)

Canonical namespace is now MJR_AM_... to avoid collisions with ComfyUI/global environment variables.

Compatibility aliases are still accepted (MAJOOR_... and some MJR_... names), but new deployments should prefer MJR_AM_....

API Token Setup

The API token is user-defined. Set MAJOOR_API_TOKEN (or MJR_API_TOKEN) before starting ComfyUI.

Windows (PowerShell):

$env:MAJOOR_API_TOKEN = "my-secret-token"

Windows (CMD):

set MAJOOR_API_TOKEN=my-secret-token

Linux / macOS:

export MAJOOR_API_TOKEN="my-secret-token"

Once set, include the token in your API requests via one of these headers:

X-MJR-Token: my-secret-token
Authorization: Bearer my-secret-token

Scenario	Behavior
No token set (default)	Write operations allowed only from localhost (`127.0.0.1` / `::1`)
Token set	All write operations require the token
`MAJOOR_REQUIRE_AUTH=1`	Forces token auth even for localhost

Security Summary

Without token: write operations are localhost-only.
With token: write operations require authentication.
Safe Mode is enabled by default.
Destructive operations (delete/rename/open-in-folder) are disabled by default and must be explicitly enabled. You can persist the same secret in ComfyUI's Settings modal under Security -> Majoor: API Token. The Assets Manager stores it in browser storage and automatically sends both X-MJR-Token and Authorization: Bearer ... on behalf of the UI, so remote clients only need to match the shared secret between the backend environment and the settings field. The backend still requires the environment variable (MAJOOR_API_TOKEN/MJR_API_TOKEN) when ComfyUI starts; the UI control just remembers it for you so the headers stay in sync.

Security Model (high level)

CSRF: state-changing endpoints require X-Requested-With: XMLHttpRequest (or X-CSRF-Token) and validate Origin vs Host when present.
Rate limiting: in-memory per-client limits exist on expensive endpoints (search/scan/metadata/batch-zip). Client identity is based on IP; X-Forwarded-For is only honored when the connection comes from MAJOOR_TRUSTED_PROXIES.
Path safety: file operations validate root containment for output/input/custom roots and reject paths outside allowed roots (symlink/junction handling is opt-in).
Write access: destructive actions are loopback-only by default unless a token is configured.
Safe Mode: write operations are disabled by default unless explicitly enabled via environment variables.
Batch ZIP: ZIP building streams from an open file handle (avoids TOCTOU rename/replace races).

UI Preview

Files & Storage

Index DB: <output>/_mjr_index/assets.sqlite
Custom roots store: <output>/_mjr_index/custom_roots.json
Collections store: <output>/_mjr_index/collections/*.json
Temporary drag-out ZIPs: <output>/_mjr_batch_zips/ (auto-cleaned)

Troubleshooting (DB Corruption)

If the index DB is too corrupted, use the emergency endpoint:

POST /mjr/am/db/force-delete

This force-deletes the SQLite files, recreates a clean DB, then triggers a rescan.

Manual fallback (with ComfyUI stopped):

Delete:
- assets.sqlite
- assets.sqlite-wal
- assets.sqlite-shm
Location: <output>/_mjr_index/
Restart ComfyUI, then run a scan/reset index.

Development

python -m pytest -q

Type/lint checks:

python -m mypy --config-file mypy.ini
python -m ruff check mjr_am_backend mjr_am_shared tests
python -m black --check mjr_am_backend mjr_am_shared tests

Tests (Windows)

Batch runners generate both JUnit XML and a styled HTML report in tests/__reports__/:

Full suite: run_tests.bat (or tests/run_tests_all.bat)
Quick suite (skips the long Comfy output scan): run_tests_quick.bat
Metadata / parser suite: run_tests_parser.bat (runs tests/metadata/)

Open the report index:

tests/__reports__/index.html

Test runtime DB artifacts (*.db, *.db-wal, *.db-shm, etc.) are created under:

tests/__pytest_tmp__/

Parser samples scan (metadata suite):

Put sample files under tests/parser/ (subfolders supported), or set MJR_TEST_PARSER_DIR to an external folder.

Release (zip)

On Windows, build a clean drop-in zip (excludes .git/, caches, etc.):

pwsh -File scripts/make_release_zip.ps1

Architecture

mjr_am_backend/ - Python backend (routes + features)

Upgrade Guide (Major ComfyUI Changes)

When ComfyUI introduces major frontend/backend API changes:

Update to a pinned ComfyUI stable tag first.
Verify route registration and /mjr/am/health in the browser.
Run compatibility tests (tests/compat/*) and full pytest.
Check frontend bridge (js/app/comfyApiBridge.js) for API surface changes.
Re-validate i18n + settings registration in UI.

Viewer Roadmap (bigger items)

GPU grade (WebGL2): exposure/gamma/channels/zebra/false color.
OffscreenCanvas + Worker fallback for heavy processing.
Cache processed frame while paused (instant grade tweaks).
