Not copied from the project's own blurb. These are things we opened and verified, with the date.
- 11 Sept 2026We checked that the link to the project still resolves.
- 30 Aug 2026We read the project's own documentation and found no sign that development has stopped.

- Commercial use confirmed as allowed74 of 211

Only 19 of the 211 meet all of the conditions above.
Counted from our own checks: every tool we list is examined against the same criteria.
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.
