Workflow Studio

About

A centralized control UI for managing ComfyUI workflow JSON files, generating images via API, assisting with prompt creation, and browsing/organizing nodes.

• Install via ComfyUI Manager or git clone to custom_nodes
• Launch from the Workflow Studio button in the ComfyUI toolbar, or open http://127.0.0.1:8188/wfm

Workflow Tab

• Switch between Thumbnail, Card, and Table view modes
• Search, category filter, favorites filter, and group filter
• Create, rename, delete groups and assign/remove workflows
• Import JSON/PNG files via button or drag & drop
• Side panel: thumbnail, JSON viewer (format badge: UI/API/App), clipboard copy, group management
• Detail modal: rename, favorite, thumbnail change, badge assignment, tags, memo, AI summary, open in ComfyUI, load in GenerateUI, set as default, delete
• Badge management: add, rename, delete badges with custom colors shared with the Models tab (⚙ Badge button)

GenerateUI Tab

• Connect/disconnect ComfyUI and check connection status
• Load workflows from Workflow tab (App format .app.json not supported)
• 4-tab layout — Input (Prompt + Image), Model, Settings, Feeder — Input/Model/Settings each include a Raw JSON column for instant preview and direct editing
• Input tab: Prompt (top) and Image drag-and-drop (bottom) in the left column
• Model tab: Checkpoint, VAE, LoRA, ControlNet, UNET, TextEncoder selectors with filter
• Settings tab: KSampler and Latent Image side by side, each at 50% width
• Raw JSON always visible in the right column of each tab — edit directly and Apply to reload the workflow
• Seed control: random, fixed, increment, decrement — seed input and mode selector stacked vertically for readability
• Generate, progress display, stop, and view results
• Eagle integration: auto-save generated images to Eagle
• Checkpoint Batch: select checkpoints by folder from the dropdown — check a folder to select all its files, or expand with ▶ to check individual files; use Filter to search; Pause/Resume suspends and continues between models; Stop aborts after the current generation

GenerateUI Tab — Feeder subtab

Requires the comfyui-image-feeder custom node. Controls ImageFeeder nodes and runs continuous generation loops over an image library stored in user/default/image-loop-data/.

• Left pane — Node settings: select the target ImageFeeder node from the dropdown; edit all node parameters (Directory, Sort Mode, Index, Start/End Index, Batch Size, Seed, Use Selection); click Apply to write changes to the loaded workflow
• Left pane — Presets: save the current directory + selection as a named preset; load or delete saved presets
• Left pane — Run: After gen mode determines index behavior after each generation — Loop (wrap back to 0 and continue indefinitely), Increment (advance index and stop when all images are exhausted), Fixed (always use the same index); click Run to start the loop, Stop to interrupt
• Center pane — Folder tree: browse subfolders inside image-loop-data; click a folder to load its images; click ↺ to reload the tree
• Center pane — Image grid: displays thumbnails of all images in the selected folder; check individual images to add them to the selection; All / None buttons select or clear the entire folder; click an image to open the preview panel
• Center pane — Preview panel: shows the clicked image at larger size with filename, resolution, and file size
• Status bar: shows the current folder path and how many images are selected out of the total in the folder
• Seed during Run: uses the right-pane seed setting (Random / Fixed / Increment / Decrement) — the ImageFeeder's own Seed field controls random sort order only
• Index sync: after each generation the node returns the next index via WebSocket; the Index field updates automatically so the display stays in sync

Prompt Tab

• AI assistant (Ollama): model selection, chat for prompt consultation, image attachment (vision models)
• Apply AI responses to GenerateUI prompts
• Translation: JA↔EN, ZH↔EN
• Preset management: create, edit, positive/negative prompt clipboard copy (PP/NP)
• Preset Manager: browse all presets, favorites, and group-based filtering
• Group management: create groups, assign/remove presets, delete groups
• GenUI Set: apply preset prompts directly to GenerateUI
• Wildcard toolbar: one-click buttons to insert wildcard syntax ({|}, {n$|}, __|__, <lora:>, etc.); wraps selected text
• Wildcard file manager: create/edit/delete .txt/.yaml wildcard files; click filename to insert __filename__ at cursor

Settings Tab

• UI language and summary language
• Theme selection (13 presets) with customization: color overrides, background patterns (stripes, polka dot, checkerboard, SVG tiling), and font selection (16 Google Fonts including Japanese display fonts)
• Workflow data folder path
• ComfyUI connection URL and test
• Ollama URL, default model, and connection test
• Default workflow setting
• Eagle integration URL and auto-save toggle
• Data Management: export all plugin data to JSON / import to restore
• All sections are collapsible accordion panels
• Wildcard Integration: link WFS wildcard dir to ComfyUI-Impact-Pack wildcards (junction/symlink); existing files migrated automatically

Nodes Tab

• Node Browser: search by name/description/alias/tag, filter by category, package, tag, group, favorites
• Card and Table view modes with pagination
• Favorite nodes and add custom tags for organization
• Create, rename, delete node groups and assign/remove nodes
• Side panel: Details (class name, package, category, description, flags), I/O Spec (inputs/outputs with types and defaults), Groups management
• Node Sets: create reusable node collections with descriptions, tags, and link definitions between nodes

Gallery Tab

• Browse images in the ComfyUI output folder — set the folder path in Settings > Gallery Output Folder
• 3-column layout: folder tree (left) | image grid (center) | detail panel (right)
• Thumbnail and Table view modes; double-click any image to open fullscreen lightbox
• Toolbar filters: favorites (★), text search, tag filter, group filter, sort by date/name
• Folder tree: click to load images, expand with ▶; "+ New" creates a subfolder inside the selected folder, "Del" deletes it with all contents
• Multi-select with Ctrl+click — bulk operations: Add to Group, Favorite All, Unfavorite All, Move To..., Delete
• Detail panel — Info tab: filename, size, date, tags (add/remove), memo; "Move To..." moves the image to another folder, "Delete" removes it permanently
• Detail panel — Metadata tab: displays workflow JSON from PNG embedded data (prompt / workflow keys) or from metadata saved by the Generate UI tab; one-click clipboard copy
• Detail panel — Groups tab: create, assign, remove, rename, and delete groups per image
• Workflow auto-save: images generated in the Generate UI tab automatically have their workflow saved to gallery metadata and shown in the Metadata tab
• Supports PNG (tEXt/iTXt), JPEG, WebP, GIF; workflow extraction reads ComfyUI prompt and workflow keys embedded in PNG metadata

Models Tab

• Browse installed models: Checkpoint, LoRA, VAE, ControlNet, UNET, TextEncoder, Hypernetwork, Embedding with sub-tab switching
• Thumbnail, Card, and Table view modes with pagination
• Search, tag filter, group filter, favorites filter, and status filter (All / Enabled only / Disabled only)
• Side panel: Info (file path, tags, memo), Groups management, CivitAI integration
• CivitAI integration: fetch model info by SHA256 hash, batch fetch per model type
• Detail modal: preview image, CivitAI info (base model, trained words, tags), thumbnail change
• Group management: create, rename, delete groups and assign/remove models
• GenUI Model button: apply the selected model to the corresponding node in GenerateUI's current workflow (Checkpoint / LoRA / VAE / ControlNet / UNET / TextEncoder)
• User-defined badges: assign free-label badges with custom colors shared with the Workflow tab
• Enable/Disable models: toggle visibility in ComfyUI by renaming file extension (.disabled suffix). Disable per model (⏸ button on each card) or per group (Enable All / Disable All in Group panel). Changes take effect after ComfyUI refresh.
• Multi-select & bulk operations: click Select to enter selection mode, check multiple models, then use the bulk action bar to add/remove from groups or permanently delete files (model file + preview images + sidecar files such as .json/.info).
