ComfyUI alternatives

Looking for a ComfyUI alternative?

ComfyUI is centered on Stable Diffusion, so anything past diffusion images — video, audio, agents — means leaving the graph. If that's what has you looking, here are the alternatives worth weighing — and why teams pick NodeTool, the open source, BYOK canvas for image, video, audio, and text.

Frequently asked questions

What is the difference between NodeTool and ComfyUI?
ComfyUI is a node editor focused on Stable Diffusion and diffusion image generation with an engineer-first UX. NodeTool is the studio around it: image, video, music, and text on one node-based canvas, a much wider model roster across providers and modalities, and editing tools creatives actually use — called with your own keys at provider prices. Both are node-based and open source.
Is NodeTool open source like ComfyUI?
Yes. NodeTool is open source under AGPL-3.0. You can run it as a desktop app on macOS, Windows, or Linux, or in the browser via NodeTool Cloud, which is managed hosting of the same open-source code.
Can NodeTool do more than image generation?
Yes. NodeTool works across image, video, audio, and text on one canvas, with editing tools built in — masks, inpaint, outpaint, relight, upscale, layers, and compositing. ComfyUI is centered on diffusion image generation.
How does NodeTool handle model pricing?
NodeTool is BYOK — you bring your own API keys and pay each provider their list price. There are no credits, no markup, and no curated roster. You can also run local models with Ollama, MLX, or llama.cpp in the desktop app.
