ThinkDiffusion review: Cloud workspaces for running Stable Diffusion, ComfyUI and other open-source AI apps

What ThinkDiffusion does

ThinkDiffusion rents you a private cloud machine preloaded with open-source image and video generation software, so nothing has to be installed or maintained locally. The apps include Automatic1111, ComfyUI, Forge, Fooocus and Kohya, the last of which is meant for training and fine-tuning your own models and LoRAs. You can add extensions and custom nodes, and bring models from Civitai, Hugging Face or your own computer with a one-click upload.

Each machine is dedicated to a single user, and files, models and settings persist in a personal drive as long as the subscription is active. Several machines can be launched side by side.

The pricing page covers the TD-TEAMS plan, which costs $59.99 per month. It adds 20% discounted machine rates and includes a $20 balance credit every month, 2 team members and a 200 GB default workspace. Additional members are an add-on at $6 per member per month, and extra workspaces are sold in storage sizes. Admins can create isolated workspaces for separate projects or clients, share models and extensions inside each one, and cap individual members' usage.

The homepage mentions a free trial period, but gives no length. The pages do not show a free plan or a yearly-billing price. Machines range from 16GB to 48GBs of VRAM. Files are deleted within 48 hours after a subscription expires. There is no direct integration with tools such as Adobe Suite, though Automatic1111 and ComfyUI expose built-in APIs for technical users.

• Cloud workspaces for Stable Diffusion, ComfyUI, Flux, Forge and Kohya
• One-click model upload from Civitai, Hugging Face or local files
• Extensions for Automatic1111 and custom nodes for ComfyUI
• Dedicated machine per user
• Run several machines simultaneously
• Model and LoRA training with Kohya
• Isolated team workspaces
• Per-member usage limits set by admins
• File browser available without a running machine

Our take

ThinkDiffusion suits people who already want to work with open-source generation tools like ComfyUI or Automatic1111 but would rather not buy a GPU or manage installs. Teams, classes and agencies get the clearest fit, because the Teams plan adds shared workspaces, isolation between projects and per-member usage limits. Solo users will find no individual prices on the pricing page we reviewed, and no free plan is stated, only a trial of unspecified length. It is a poor match if you need ready-made hooks into Adobe tools or filtered content by default. Storage is tied to an active subscription, so plan for exports before cancelling.
