For Developers

Experiment in UI. Deploy via API. Zero Infrastructure.

ComfyUI workflows perfected by your design team become production-ready APIs instantly

Same environment, identical results, transparent pricing. No servers, no scaling, no maintenance - just reliable API endpoints.

Unified Platform

Perfect workflows in the UI, deploy via API with identical results

Zero DevOps

No servers, no scaling, no maintenance - just reliable API endpoints

Transparent Pricing

Pay only for actual generation time, monthly plans start at $10

Building AI Features Shouldn't Require Infrastructure Expertise

From creative experiment to production API in minutes

Your team has ComfyUI workflows that create amazing results, but moving from experimentation to production is painful. Setting up GPU infrastructure, managing dependencies, handling scaling, dealing with "works on my machine" problems when creative handoffs break in production.

Meanwhile, your product roadmap is waiting on AI features that should take days, not months.

What if your creative team's workflows became production APIs instantly?

AI Generation Infrastructure Is a Nightmare

Your designer sends you an amazing ComfyUI workflow. Now you need to dockerize it, manage GPU instances, handle queuing, implement caching, ensure consistency, monitor costs...

Or you could just call our API.

What You Don't Want to Manage

Environment Hell

Dependencies, model versions, breaking changes

GPU Management

Provisioning, scaling, GPU drivers, CUDA versions

Workflow Translation

Designer mockup ≠ Production code

Cost Unpredictability

Pay for idle GPUs, surprise bills

Reliability Issues

"Works locally" but fails in production

Focus on Your Product, Not GPU Management

Infrastructure Abstraction

Make API calls. That's it. No GPU management required.

Unified Development Flow

Designers iterate in ComfyUI, developers get working code instantly

Same Platform, Same Results

No translation layer between design and production

True Serverless Pricing

Pay only for GPU computation time - no idle charges

80-90% Cost Reduction

Transparent per-second billing vs GPU instances

From Creative Experiment to Production API in Minutes

Three pillars of developer-friendly AI integration

1. Unified Development Workflow

  • Designers perfect workflows in familiar ComfyUI interface
  • Developers deploy identical workflows via REST API
  • No rebuild, no translation, no environment differences
  • Generated API code matches UI behavior exactly

2. Zero Infrastructure Management

  • Auto-scaling from 0 to enterprise load
  • Multi-GPU orchestration handled automatically
  • 99.9% uptime SLA with monitoring
  • No Docker, Kubernetes, or GPU expertise required

3. Developer-Friendly Integration

  • RESTful API with comprehensive documentation
  • Real-time status updates via webhooks or polling
  • Transparent error handling and debugging
  • Code examples in Python, JavaScript, curl

The Only AI Platform Where UI Equals Production

Your creative team's workflows become your production infrastructure

1. Creative Team Perfects Workflow

Designer uses ComfyUI interface → Perfect result

2. Generate Production API Code

Auto-generated from UI workflow with exact configuration

3. Deploy to Production

Same environment, identical results, zero config

4. Scale Automatically

No capacity planning, no cold starts, no downtime

# Auto-generated from UI workflow
run
=
run_workflow
({
"workflow_id": "XXX",
"prompt": ..., # ComfyUI workflow JSON
"accelerator": "H100"
})

ComfyICU maintains a standardized environment with 95 pre-installed nodes, ensuring workflows work identically in UI and production. This managed approach eliminates deployment complexity while maintaining ComfyUI's full power.

Simple Integration, Powerful Results

Get started with just a few lines of code

Python Integration

Python
import requests
  import os
  import time
  
  def run_workflow(workflow_data):
      url = f"https://comfy.icu/api/v1/workflows/{workflow_data['workflow_id']}/runs"
      headers = {
          "Authorization": f"Bearer {os.environ['COMFYICU_API_KEY']}",
          "Content-Type": "application/json"
      }
      response = requests.post(url, headers=headers, json=workflow_data)
      return response.json()
  
  # Usage
  run = run_workflow({
      "workflow_id": "XXX",
      "prompt": {...},
      "accelerator": "H100"
  })
  
  print(f"Job started: {run['id']}")

Node.js/JavaScript

JavaScript
async function generateImage(workflowData) {
    const response = await fetch(`https://comfy.icu/api/v1/workflows/${workflowData.workflow_id}/runs`, {
      method: 'POST',
      headers: {
        'Authorization': `Bearer ${process.env.COMFYICU_API_KEY}`,
        'Content-Type': 'application/json'
      },
      body: JSON.stringify(workflowData)
    });
    
    const run = await response.json();
    return await pollForCompletion(workflowData.workflow_id, run.id);
  }

Webhook Handler

Flask/Python
@app.route('/comfyicu-webhook', methods=['POST'])
  def handle_completion():
      data = request.json
      
      if data['status'] == 'COMPLETED':
          # Process generated assets
          for output in data['outputs']:
              process_generated_asset(output['url'])
              
      return jsonify({'status': 'received'})

Common Developer Questions

Everything developers need to know about integrating ComfyICU

How do I get workflows from the UI to production?

Use any workflow from the UI, click 'View API Code' on a successful run, and copy the generated code. It works identically in production.

What's the difference between your API and hosting ComfyUI myself?

Zero infrastructure management, automatic scaling, 95 pre-installed nodes, and 80-90% cost savings. We handle the DevOps so you focus on features.

Can I use custom models and LoRAs?

Yes, provide public URLs (S3, CivitAI, HuggingFace) and we'll download them automatically. They're cached for subsequent requests.

How does billing work for variable usage?

Credit-based within your monthly subscription tier. If you exceed your credits, purchase additional credits with volume discounts. No surprise charges beyond your plan.platform fees

Do you support webhooks?

Yes, provide a webhook URL when creating runs. We'll POST status updates including completion and error states.

What about team access and permissions?

PRO ($60) and higher include team features with role-based access, API key management, and usage analytics.
