Spec score 8.9 #14 of 124 in AI image generators

What it is

SwarmUI is a modular web interface for generating images with AI, with support for video and some audio models. Its listed image models include Krea 2, Stable Diffusion, and Flux; video examples include MiniMax H3, Wan, and LTX-2, and ACE-Step is listed for audio. A beginner-oriented Generate tab sits alongside a Comfy Workflow tab that exposes the raw graph for advanced work. SwarmUI can install ComfyUI and use it as a backend, or connect to AUTOMATIC1111. Its tools include an image editor, automatic workflow generation, and Grid Generator, and users can add extensions and custom node packs. By default, it runs on the user's own computer and says it collects no user data. Windows, Linux, and M-Series Mac are listed as compatible; a modern GPU is required, with Nvidia RTX 30xx or newer recommended. Cloud GPU options include a free Google Colab option and templates for Runpod and Vast.ai. SwarmUI is free and open source under the MIT License.
