ThinkDiffusion
Managed Stable Diffusion and ComfyUI in your browser
About ThinkDiffusion
ThinkDiffusion is a managed cloud platform purpose-built for Stable Diffusion. It launches pre-configured Automatic1111, Forge, ComfyUI, and Fooocus instances in your browser within seconds — no installation, no CUDA driver headaches, no model downloading. The platform targets artists and creators who want to run heavy SD workflows on cloud GPUs without becoming a sysadmin.
Pros & Cons
Pros
- Zero setup — generate your first image within 2 minutes of signing up
- Pre-installed model library saves hours of downloads and gigabytes of bandwidth
- Includes all the popular SD UIs (A1111, ComfyUI, Forge, Fooocus) in one subscription
- Browser-only access means it works from any device, including iPads and Chromebooks
- Persistent storage so your custom workflows and trained LoRAs are always one click away
Cons
- Hourly rate is 2-4x higher than raw GPU clouds like Vast.ai or RunPod
- Less control than SSH-based clouds — can't install arbitrary system packages
- GPU choice is limited to ThinkDiffusion's curated tiers, not the full NVIDIA catalog
- No serverless inference — you pay while the machine is running even when idle
