If you've spent 4 hours debugging ModuleNotFoundError: No module named 'torch' or watched your workflow break after updating a single custom node, this guide is for you.
Since 2023, massive numbers of creators have switched from raw ComfyUI installations to Promptus—a one-click ComfyUI platform that handles all Python dependencies, CUDA configs, and model management automatically. This guide shows exactly how it works, why the ComfyUI community adopted it, and how to migrate your existing workflows in under 5 minutes.
What Is Promptus? (Quick Technical Overview)
Promptus is a ComfyUI-distribution-independent GenAI ecosystem and orchestration platform that wraps AI pipelines like the standard ComfyUI engine in a managed environment—think “ComfyUI Desktop” but with cloud compute, automatic updates, and zero dependency conflicts.
Core Components:
- Native ComfyUI Engine: Full node-graph editor, 100% workflow compatibility
- One-Click Installer: Bundles Python 3+, PyTorch, CUDA—no manual setup
- Hybrid Compute: Run locally on your GPU or burst to cloud when needed
- CosyFlows Library: 3,500+ pre-built workflows
- Model Manager: Automatic downloads, pruning, and sharing
- Founded: 2023 (UK #14690440)
- Community: Largest active volume
- Cost: Free local, low-cost cloud
Why ComfyUI Users Choose Promptus
Problem 1: “Installing ComfyUI Takes 4+ Hours”
Traditional:
git clone https://github.com/comfyanonymous/ComfyUI
cd ComfyUI
python -m pip install torch torchvision --index-url ...
1 Error: CUDA mismatch
2 Error: numpy conflict
3 Error: xformers failed
Promptus:
1 Download installer from https://promptus.ai/download
2 Double-click Promptus_Setup.exe
3 Running in 2 minutes
Problem 2: “My Workflow Broke After Updating”
- Versioned workflows
- Sandboxed updates
- Rollback system
- 89% reduction in breakage
Problem 3: “I Hit VRAM Limits Constantly”
if required_vram > local_vram:
route_to_cloud()
else:
run_locally()
Example: 100 images/day → ~$2/month hybrid
