SwarmUI

What it does

Drives ComfyUI and other backends from a single interface, switching between a simple view and a full node-level one, and tends to support new models early. Handles multi-GPU and multi-machine distribution, model management and extensions. This is the maintained continuation of StableSwarmUI after Stability AI stopped supporting it in June 2024 — the original developer carries it on. Setup is real work, and model licences, not the app's MIT, govern what you may do with the output.

SwarmUI FAQ

Is SwarmUI free?

Yes. It runs on your own machine, so there is no usage-based cost either.

Do I need to install anything or write code to use SwarmUI?

It needs the command line. If you are not comfortable typing commands, expect to get stuck during setup.

Does SwarmUI work on a phone?

No. It needs a computer.

Can I use SwarmUI commercially?

The licence is MIT, which permits commercial use. Conditions such as keeping the copyright notice still apply, so read the licence text before shipping it inside something.
