ComfyUI
Most powerful and modular diffusion model GUI, api and backend with graph/nodes interface.
Build and reuse complex diffusion workflows using a powerful visual node graph interface.
ComfyUI is a modular diffusion model GUI, API, and backend featuring a visual node graph interface for content creation. It suits visual professionals who demand precise control over models, parameters, and pipelines.
What it is
It provides a visual node graph for building image, video, audio, 3D, and text workflows without code. You can manage smart VRAM allocation, model offloading, and asynchronous queueing locally or via API.
Who it's for
It suits visual professionals who need granular control over generative AI pipelines and custom nodes. It does not suit beginners looking for a simple, out-of-the-box prompting interface without node management.
Key features
Visual Node Graph
Build and reuse complex image, video, audio, and text workflows without writing code.
Broad Model Support
Run native open-source models like Stable Diffusion, Flux, and Wan alongside partner nodes.
Smart VRAM Management
Execute pipelines efficiently using asynchronous queueing, partial re-execution, and model offloading.
Workflow Serialization
Save and load complete workflows as JSON or recover full workflows directly from generated media.

Our honest verdict
What's great
- Modular node graph interface provides absolute control over every parameter and model component
- Native support for a vast range of open-source image, video, audio, and 3D models
- Built-in local API for seamlessly integrating complex workflows into production applications
- Recover complete workflows and exact seeds directly from supported generated media files
Where it falls short
- Requires significant technical skill to construct and debug complex node workflows
- Managing local GPU hardware, VRAM limits, and custom node dependencies demands active effort
- Commits outside of stable release tags can break custom nodes and existing workflows
