New Source Connector: ComfyUI Cloud API

[Vincent Lange (vincent-el)]

Connector Proposal: source-comfyui

What

A source connector for the ComfyUI Cloud API that extracts generation jobs, assets, models, nodes, and system data from ComfyUI Cloud into any Airbyte destination.

Why

ComfyUI is the most widely-used open-source AI image/video generation platform (4M users, 60K+ community nodes, 150K+ daily downloads). The Cloud API provides a production-grade REST interface for managing AI generation workflows. There is currently no Airbyte connector for any generative AI workflow engine — this would be the first.

Use cases:

• Analytics teams at creative studios tracking generation costs, GPU utilization, and model performance
• Data teams building observability over AI generation pipelines
• Researchers analyzing workflow patterns and node usage across large-scale generation
• Creative production teams feeding generation metadata into data warehouses for reporting

Streams

Stream	Endpoint	Sync Mode	Description
jobs	GET /api/jobs	Incremental	Generation job history with status, timing, workflow refs
job_details	GET /api/jobs/{id}	Incremental	Full job data: workflow graph, outputs, execution metadata
assets	GET /api/assets	Incremental	User assets with tags, metadata, sizes
models	GET /api/models/{folder}	Full Refresh	Available AI model catalog
nodes	GET /api/object_info	Full Refresh	Node type catalog (inputs, outputs, categories)
system_stats	GET /api/system_stats	Full Refresh	System info (GPU, VRAM, versions)

Implementation

• Built with: Python CDK (airbyte-cdk)
• Auth: API key via X-API-Key header
• Pagination: Offset/limit with has_more flag
• Incremental sync: Cursor-based on create_time (jobs) and created_at (assets)
• Tests: 53 unit tests passing
• Ready to submit: Full connector with Dockerfile, schemas, README, icon

About ComfyUI

ComfyUI is the AI creation engine for visual professionals. Open-source node-based interface for Stable Diffusion, Flux, and other generative models. Used by OpenAI, Netflix, Amazon Studios, Ubisoft, EA, Tencent. Recently raised $30M at $500M valuation.

I am a data platform engineer and ComfyUI practitioner — happy to maintain this connector and iterate on feedback.
