Node-based visual AI studio for images, video, 3D and audio
Connect models, samplers, conditioning, LoRAs and output nodes on an infinite canvas where every step is visible and adjustable.
One interface for image generation, video, 3D assets and audio or music workflows, with support for leading open and partner models.
Run ComfyUI locally on your own GPU, or open the same workflows in the cloud when you don't have the hardware.
Deploy any workflow as a production API so your own app or agent can generate outputs on demand.
Free online Stable Diffusion XL image generation with a searchable library of nine million prompts
Generate photo-realistic images from text prompts using Stable Diffusion XL directly in the browser, with no GPU or software install required.
Search over 9 million Stable Diffusion prompts shared from around the world, then reuse or adapt them for your own generations.
Add or replace parts of an existing image, or extend a picture beyond its original borders to re-frame a composition.
