SwarmUI
What SwarmUI is
SwarmUI is a modular web interface for generating AI images, with support for video and some audio models. It is free and open source under the MIT License. By default, it runs on the user's computer and says it does not collect user data. Listed image models include Krea 2, Stable Diffusion, and Flux; video examples include MiniMax H3, Wan, and LTX-2, while ACE-Step is listed for audio. The Generate tab is intended for beginners, and a Comfy Workflow tab exposes the raw graph for advanced users. SwarmUI can install ComfyUI and use it as a backend, and it also supports AUTOMATIC1111. Users can build extensions and custom node packs; named tools include an image editor, automatic workflow generation, and Grid Generator. Windows, Linux, and M-Series Mac are listed as compatible. A modern GPU is required, with Nvidia RTX 30xx or newer recommended; other GPUs may work with limitations. Cloud options include a free Google Colab option and templates for Runpod and Vast.ai. The README describes SwarmUI as being in “Almost-Release” status.
Who it suits
SwarmUI may suit beginners who want a Generate tab and advanced users who want raw graph access. It also fits users seeking local operation or cloud GPU options, provided their setup meets the hardware requirements.
What it does well
- Free and open source under the MIT License.
- Runs locally by default and says it collects no user data.
- Supports image, video, and some audio models.
- Offers ComfyUI and AUTOMATIC1111 backend options.
What to know first
- A modern GPU is required.
- Other GPUs may work with limitations.
- The README says the project is in “Almost-Release” status.
Limits
A modern GPU is required for local use, with Nvidia RTX 30xx or newer recommended. Other GPUs may work with limitations. LLM-assisted prompting is a feature target that is not yet implemented natively.

Getting started
- Visit the SwarmUI website and choose a compatible Windows, Linux, or M-Series Mac setup.
- Prepare a modern GPU; Nvidia RTX 30xx or newer is recommended.
- Use the local installation, or choose the free Google Colab option for cloud GPU use.
- Start with the Generate tab or open the Comfy Workflow tab.
- Optionally install or connect ComfyUI, or use AUTOMATIC1111 as a backend.
Verdict
SwarmUI combines image generation with video and some audio model support, plus tools for simpler and more advanced workflows. A modern GPU is required for local use, and the README identifies the project as still in “Almost-Release” status.
