ComfyUI Review 2026 — Best Open-Source AI Image Generation UI
ComfyUI is the professional node-based UI for Stable Diffusion. Supports Flux.1, SDXL, SD3, ControlNet, and 500+ extensions. 60K+ GitHub stars.

ComfyUI lets users connect models, processing steps, parameters, and outputs on a visual node graph. Workflows can be saved, reused, extended with custom nodes, and run locally on supported hardware or through Comfy Cloud.
It is used by artists, developers, VFX teams, advertisers, game studios, and researchers. The local application is free and runs offline, while Comfy Cloud, Partner Nodes, API usage, storage, and some model licenses cost extra.
