ComfyUI at a glance
Checked 15 Oct 2026ComfyUI builds generation pipelines as node graphs and supports a long list of open image models (SD 1.5, SDXL, SD3.5, Flux.1, Flux.2, Qwen Image, Z-Image and more). It ships a desktop app (Windows, macOS), a Windows portable build and a manual install, and claims to run large models on 4GB VRAM + 8GB RAM. Code is GPL-3.0; there is no default model, so the weights licence is whatever you load. Paid API nodes and Comfy Cloud are optional and can be disabled with --offline.
RepoQuarry. “ComfyUI.” Checked 15 Oct 2026. https://repoquarry.dev/projects/comfyuiHow much of Midjourney does it replace?
4 of 4 jobs. Covers all four jobs with open models you pick and wire up yourself; quality and licence depend on the model.
How much of Adobe Firefly does it replace?
3 of 3 jobs. Inpainting, outpainting and reference conditioning are built in; no Adobe app integration.
How much of Suno does it replace?
1 of 5 jobs. Makes songs through the YuE2 text-to-music workflow (official ComfyUI template); the YuE2 weights are non-commercial except for individual creators.
For instrumental tracks (Instrumental mode), covers and restyles of an uploaded song (Cover), extending or regenerating part of a song (Extend, splitting a song into vocal and instrument stems (Get Stems), see other Suno alternatives. You may also need to build an interface, an API server and hosting yourself.
