comfypod

CLI tool for running ComfyUI on RunPod with persistent model storage.

Why?

Running ComfyUI on cloud GPUs has a few pain points:

• GPU time is expensive - Downloading models (often 10-50GB+) wastes expensive GPU hours
• Data disappears - Stopping a pod deletes everything, forcing re-downloads every session
• Setup is repetitive - Manually installing the same models and custom nodes each time
• Security concerns - RunPod proxy URLs have no built-in authentication

comfypod solves these by:

• Using cheap CPU pods for model downloads, storing them on a persistent Network Volume
• Keeping your models safe when GPU pods are stopped (pay only for storage)
• Defining your environment in a config file for reproducible setups
• Adding Basic Auth protection automatically

Features

• Network volume for persistent model storage (pay only for storage when not using GPU)
• Automatic model downloading from HuggingFace and Civitai
• Custom node installation
• Basic auth protection for web UI

Installation

npm install comfypod

Setup

1. Create comfypod.config.ts:

import { defineConfig } from "comfypod";

export default defineConfig({
  dataCenterId: "EU-CZ-1",
  gpu: {
    typeIds: ["NVIDIA GeForce RTX 3090"],
  },
  models: [
    {
      url: "https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0/resolve/main/sd_xl_base_1.0.safetensors",
      dest: "checkpoints/sd_xl_base_1.0.safetensors",
    },
  ],
  customNodes: [{ repo: "https://github.com/ltdrdata/ComfyUI-Manager" }],
});

Tokens default to environment variables (RUNPOD_API_KEY, HF_TOKEN, CIVITAI_TOKEN) but can be overridden in config.

Usage

# Estimate network volume size needed
npx comfypod estimate

# Download models to network volume (uses cheap CPU pod)
npx comfypod setup

# Start GPU pod with ComfyUI
npx comfypod start

# Check status
npx comfypod status

# Stop and delete GPU pod (keeps network volume)
npx comfypod stop

# Delete everything including network volume
npx comfypod cleanup

Options

npx comfypod <command> --config <path>
npx comfypod <command> -c <path>
