DiffusionHub: historical overview
DiffusionHub was a hosted Stable Diffusion workspace that let creators launch private cloud GPU sessions with Automatic1111, ComfyUI, Fooocus, or Kohya instead of installing the tools locally. The original DiffusionHub.io service is no longer active. This page is retained as a concise historical archive.

What DiffusionHub was
Founded in 2023, DiffusionHub packaged popular open-source Stable Diffusion interfaces into browser-accessible GPU instances. Users could generate and edit images, build ComfyUI workflows, install models or extensions, and use Kohya for LoRA or DreamBooth-style training without owning a powerful local GPU.
The service promoted a 30-minute trial and hourly usage starting at $0.99, with storage and higher-volume options. Those prices and allowances are historical, not current offers. The product's core idea survives in newer managed ComfyUI platforms, GPU clouds, and hosted model APIs.

Why this listing is historical
DiffusionHub no longer sells an active plan. Historical listings described a free 30-minute trial and pay-as-you-go GPU access beginning at $0.99 per hour. Those rates, storage limits, and subscription offers are not available now.
- The original DiffusionHub.io service is no longer active.
- Historical GPU rates, trial terms, storage allowances, models, extensions, security claims, and performance figures are not current.
- Projects that depended on the hosted environment must move workflows, model files, and outputs to another service or local setup.
