ComfyUI Model Linker Extension

ComfyUI Model Linker

A ComfyUI extension that relinks missing models in shared workflows: it finds the closest matches among your local files using fuzzy matching, and can download what you don't have from HuggingFace or CivitAI.

Features

• Workflow scanning — finds model references in all nodes, including nested subgraphs
• Custom node support — detects model fields of third-party loader nodes automatically by introspecting their input definitions; no hardcoded node list
• Fuzzy matching — intelligent similarity scoring finds files despite renames, different separators, or capitalization; 100% matches shown first, otherwise best matches ≥70% confidence
• Cross-platform paths — workflows authored on Windows match on Linux and vice versa (\ vs / is handled)
• Folder-aware suggestions — a file sitting in a folder the node can't load from is flagged with a "wrong folder" warning instead of silently failing at prompt time
• Auto-resolve — one click links every perfect match; also available directly from ComfyUI's native Missing Models popup
• Browse & swap — the All models tab lists every model in the workflow grouped by category; swap any of them for another local file without hunting through the node tree, applied to all referencing nodes at once
• Downloads — fetches missing models from HuggingFace/CivitAI (URLs from the workflow, a model database, or online search), with progress, speed display, bulk download, and cancel
• Safe updates — resolved models are applied to the live graph in place (no canvas rebuild); you save the workflow yourself when ready
