RunDiffusion is a cloud platform that runs open-source AI image tools like Automatic1111, ComfyUI and Fooocus on remote GPUs, so anyone can use pro Stable Diffusion workflows without owning hardware.
RunDiffusion’s idea is simple: the best image-generation tools are open source, but installing them and buying a suitable GPU is not. The service launches pre-configured cloud sessions of more than a dozen applications, including Automatic1111, ComfyUI, Fooocus, InvokeAI and Kohya for LoRA training, each ready in about ninety seconds with dozens of popular models preloaded. A smart session timer and an integrated file browser keep costs and outputs under control, and files can persist between sessions with personal storage. Alongside raw sessions, the Runnit workspace offers a simpler board-based interface that combines generation tools for less technical users. Teams get shared workspaces and storage, and commercial use of outputs is allowed, which makes the platform popular with small studios and architecture and design firms generating textures and concept art. Because sessions run the genuine open-source applications rather than a simplified clone, tutorials and community workflows found online work as written, and users can install extensions and custom nodes just as they would on a local machine.
RunDiffusion offers a 30-minute free trial, then pay-as-you-go cloud sessions starting at $0.50/hour. Runnit plans start at $8.79/month for Hobby, and the Creator’s Club membership costs $35.99/month, adding 100GB storage and server discounts.
Creators, small studios and technical artists who want full open-source Stable Diffusion workflows, custom models and training, without buying or maintaining a GPU.
