Deep Dive: Switching from Mage.Space to ComfyUI
Trade-offs, installation & data architecture
What you trade away

How to deploy ComfyUI
Windows or macOS desktop installer, Windows portable archive, or manual Python install on Windows, macOS, or Linux
What it takes to run
A compatible GPU, enough VRAM and disk for multi-gigabyte models, and a working model/workflow must be chosen before useful output appears
Where your data lives
Models, inputs, outputs, and workflow JSON live in the local ComfyUI data tree; generated media can embed workflow and seed metadata, while API nodes transmit selected inputs to their provider
Why fork ComfyUI instead of vibe-coding a Mage.Space clone?
Do not mistake the interface for the product. Mage.Space's durable value is proprietary model, inference, which a solo one-shot build cannot reproduce responsibly. The prompt therefore builds only the closest honest personal consolation tool.
