ComfyUI Model Download Manager

A robust Java Swing application to identify and download missing models for ComfyUI workflows.

Features

• Advanced JSON Parsing: Recursively scans ComfyUI JSON workflows (including subgraphs and widgets_values) for model filenames.
• Model Metadata Support: Detects and uses embedded model download metadata (URLs, directories).
• Download Manager:
  • Resume Capability: Uses HTTP Range requests to resume interrupted downloads.
  • Pause/Resume/Stop: Full control over the download queue.
  • Overwrite Protection: Prompts before overwriting existing local files.
  • Real-time Status: Shows download speed (MB/s) and per-file progress.
• Intelligent Sorting: Automatically infers the correct subfolder (e.g., checkpoints, loras, vae) based on node types.
