<h1 id="comfyui-auto-installer-v5-(python-rewrite)">🚀 ComfyUI Auto-Installer — v5 (Python Rewrite)</h1>Version 5 is a full rewrite from the ground up in Python, replacing all the PowerShell scripts from previous versions. It's cross-platform, faster, smarter, and now ships with a TUI manager, Docker images, and GPU-optimized inference out of the box.If you are upgrading from the PowerShell version (v4.x), a one-command migration preserves all your models, outputs, and custom nodes: <code>irm https://get.umeai.art/migrate.ps1 | iex</code><h2 id="quick-start-(one-liner)">⚡ Quick Start (One-Liner)</h2><ul><li>Windows (PowerShell): <code>irm https://get.umeai.art/comfyui.ps1 | iex</code></li><li>Linux / macOS: <code>curl -fsSL https://get.umeai.art/comfyui.sh | sh</code></li></ul>Only requires Git — everything else (Python, uv, dependencies) is handled automatically.<h2 id="what's-new-in-v5">✨ What's New in v5</h2><ul><li>Full Python rewrite — no more PowerShell dependency</li><li>Cross-platform — Windows, Linux, macOS, and Docker</li><li>TUI Manager — interactive terminal UI to launch, update, download models, and configure settings</li><li>VRAM-aware model catalog — 7 model families with quantization recommendations based on your GPU</li><li>GPU auto-detection — NVIDIA (CUDA 13.0/12.8), AMD (ROCm/DirectML), Apple Silicon (MPS)</li><li>SageAttention 2 + 3 — pre-compiled wheels including RTX 50XX Blackwell support</li><li>One-click update — update ComfyUI, all nodes, and dependencies with a single command</li><li>Model security scanner — detects malicious pickle code in .ckpt/.pt files</li><li>Junction architecture — models and outputs persist independently from ComfyUI updates</li><li>Docker ready — 4 image variants including a cloud version with JupyterLab for RunPod</li></ul><h2 id="prerequisites">📋 Prerequisites</h2><ul><li>Git</li><li>GPU: NVIDIA (CUDA 12.x+), AMD (Radeon RX 6000+), or Apple Silicon (M1+)</li><li>Internet connection</li><li>Note: Python is automatically installed via uv if not present.
