ComfyUI LTS

A vanilla, up-to-date fork of ComfyUI intended for long term support (LTS) from AppMana and Hidden Switch.

Key Features and Differences

This LTS fork enhances vanilla ComfyUI with enterprise-grade features, focusing on stability, ease of deployment, and scalability while maintaining full compatibility.

Deployment and Installation

• Pip and UV Installable: Install via pip or uv directly from GitHub. No manual cloning required for users.
• Automatic Model Downloading: Missing models (e.g., Stable Diffusion, FLUX, LLMs) are downloaded on-demand from Hugging Face or CivitAI.
• Docker and Containers: First-class support for Docker and Kubernetes with optimized containers for NVIDIA and AMD.

Scalability and Performance

• Distributed Inference: Run scalable inference clusters with multiple workers and frontends using RabbitMQ.
• Embedded Mode: Use ComfyUI as a Python library (import comfy) inside your own applications without the web server.
• LTS Custom Nodes: A curated set of "Installable" custom nodes (ControlNet, AnimateDiff, IPAdapter) optimized for this fork.

Enhanced Capabilities

• LLM Support: Native support for Large Language Models (LLaMA, Phi-3, etc.) and multi-modal workflows.
• API and Configuration: Enhanced API endpoints and extensive configuration options via CLI args, env vars, and config files.
• Tests: Automated test suite ensuring stability for new features.
