Comfy-Swap exposes ComfyUI workflows as stable, production-ready APIs. It bridges the gap between ComfyUI's visual workflow design and real-world application integration.

AI agents (Claude Code, Cursor, Codex, etc.) can install the comfy-swap skill to automate image generation workflows.

Install skill (recommended methods, in order):

# 1. Via skills.sh (universal, works with most agents)
npx skills add kamjin3086/comfy-swap-skill

# 2. Via openskills (Claude Code compatible)
npx openskills install kamjin3086/comfy-swap-skill

# 3. Manual clone (fallback)
git clone https://github.com/kamjin3086/comfy-swap-skill.git ~/.agents/skills/comfy-swap

After installation, agents can run comfy-swap health to verify setup, then use CLI commands to list workflows, run generations, and manage parameters.

Comfy-Swap turns complex ComfyUI workflows into simple, unified API endpoints that are:

• AI Agent Friendly — Clean JSON interface, predictable parameters, easy for LLMs and automation tools to call
• Developer Friendly — Same workflow, same parameters, whether you use REST API or CLI
• Production Ready — Stable API contracts that don't break when you update your workflow internals

curl -X POST 'http://localhost:8189/api/prompt' \
  -H 'Content-Type: application/json' \
  -d '{
    "workflow_id": "portrait-gen",
    "params": {
      "prompt": "professional headshot, studio lighting",
      "seed": 42
    }
  }'

comfy-swap run portrait-gen prompt="professional headshot" seed=42 --wait --save ./output/

Same workflow. Same parameters. Choose your interface.

• Workflow → API: Export any ComfyUI workflow as a callable API endpoint
• Parameter Mapping: Map friendly names to internal node fields (one param → multiple nodes)
• Dual Interface: REST API and CLI share identical parameters
• Image I/O: Upload images as inputs, download generated outputs
• Request Logs: Track all API calls with workflow filtering and time range
• Web Playground: Test workflows interactively before integration
• Backup/Restore: Export all configurations for migration

Comfy-Swap focuses on workflow exposure and API integration. It intentionally does not:

• ❌ Manage ComfyUI installation or updates
• ❌ Install or manage custom nodes
• ❌ Provide workflow editing UI
• ❌ Replace ComfyUI's execution engine

These are handled by ComfyUI itself or ComfyUI Manager.

Add to PATH for global access (recommended):

# Copy to a PATH location (easiest)
Copy-Item comfy-swap.exe -Destination "$env:LOCALAPPDATA\Microsoft\WindowsApps\"

# Or add custom directory to PATH permanently
$binPath = "C:\path\to\comfy-swap"
[Environment]::SetEnvironmentVariable("Path", $env:Path + ";$binPath", "User")

# Move to a standard PATH location
sudo mv comfy-swap /usr/local/bin/

# Or add to PATH in shell profile
echo 'export PATH="$PATH:/path/to/comfy-swap-dir"' >> ~/.bashrc
source ~/.bashrc

Verify installation: comfy-swap version

comfy-swap serve

Open http://localhost:8189 to complete setup.

Build from source: git clone + go build -o comfy-swap . (requires Go 1.21+)

Option A: Git Clone (Recommended)

cd /path/to/ComfyUI/custom_nodes
git clone https://github.com/kamjin3086/ComfyUI-ComfySwap.git

Restart ComfyUI after installation.

In ComfyUI: Right-click canvas → Export to ComfySwap → Configure parameters → Swap

This makes your workflow available through Comfy-Swap's unified API and CLI interface.

# REST API
curl -X POST 'http://localhost:8189/api/prompt' \
  -H 'Content-Type: application/json' \
  -d '{"workflow_id": "my-workflow", "params": {"prompt": "a cat"}}'

# CLI
comfy-swap run my-workflow prompt="a cat" --wait

# Show all commands and options
comfy-swap --help
comfy-swap run --help

Global flags: -s, --server (server URL), -q, --quiet, --json, --pretty

{
  "name": "seed",
  "type": "integer",
  "default": -1,
  "description": "Random seed, -1 for random",
  "targets": [
    { "node_id": "3", "field": "seed" },
    { "node_id": "9", "field": "seed" }
  ]
}

One seed parameter automatically updates multiple nodes. Your API stays clean.
