🚀 DaSiWa ComfyUI Installer

This script provides a one-click installation experience for ComfyUI, optimized with uv for maximum speed. It automatically handles environments, GPU detection, and my curated set of Custom Nodes - needed for my workflows.

This installer is "evergreen" - it will always download and updated versions of the installer and all logic from his repository.

🚫👾The Installer is open source and virus free. Virustotal can proof this by testing on 61 AV engines. Only Kaspersky is doing a false positive for the installer.bat.

✨ Features

ComfyUI Core: Clones the latest official repository.
Performance: Installs uv for lightning-fast package management (up to 10x faster than standard pip).
Environment: Creates a virtual Python environment (venv).
GPU Setup: Automatically detects GPUs and installs the correct PyTorch version.
Custom Nodes: Installs a predefined list from custom_nodes.txt including all sub-dependencies.
Auto-Update: The installer checks for logic updates on every start.
Starters: Creates convenient "run_comfyui" starters with predefined parameters (inside the ComfyUI folder.

🛡️ Zero-Conflict Design

This installer is designed to be "invisible" to your operating system:

Ignores Windows Store Aliases: It bypasses the "fake" Python links that often break AI installations.
No Admin Rights: Since Python is downloaded as a portable folder, you don't need administrator privileges to "install" it.
Strict Versioning: By locking to Python via config.json, we ensure high-performance libraries like Triton and SageAttention remain stable.

🛠️ Prerequisites

GPU: An NVIDIA, AMD, or Intel GPU (required for automated Torch optimization).
No Python Installation Required: The installer now uses uv to automatically download and manage a portable, isolated Python environment. You do not need to install Python on your system manually.
Internet Connection: Required for the initial download of the portable Python binary and ComfyUI components.
