    Use Cases & Benefits

    • Adds cloud storage integration nodes to ComfyUI for uploading, downloading, and managing images, video, audio, and AI models via S3-compatible providers.
    • Enables unified multi-provider cloud storage workflows with secure credential handling and caching, eliminating local storage limits and redundant downloads.
    • Use for automating cloud backup of generated media files directly from ComfyUI pipelines to providers like Backblaze B2 or AWS S3.
    • Use for sharing and synchronizing AI model files across multiple machines by downloading and caching from a central cloud bucket.
    • Use for generating presigned URLs to securely serve generated images or audio via CDN without exposing credentials or manual uploads.

    From the README

    Cloud storage nodes for ComfyUI. Save images, video, and audio to any S3-compatible provider. Download and cache models from cloud storage. Works with Backblaze B2, AWS S3, Cloudflare R2, Wasabi, DigitalOcean Spaces, and Google Cloud Storage.

    Upload generated content and manage AI models across machines using a single set of ComfyUI nodes and one boto3 dependency.

    comfyui-cloud-storage is a custom node package for ComfyUI that adds cloud storage support to any workflow. It uses the S3-compatible API shared by all major object storage providers, so a single installation covers B2, S3, R2, and more. Configure your credentials once and wire the profile to any number of save, load, or browse nodes.

    ComfyUI stores everything on the local filesystem. Generated outputs pile up on one machine with no backup. Sharing models across machines means re-downloading multi-gigabyte files from HuggingFace on each one. There is no built-in way to upload results to cloud storage or distribute models from a central bucket.
