SwarmUI
SwarmUI is a modular web interface for generating AI images, with support for AI video and some AI audio models.
What SwarmUI is
SwarmUI is a modular web interface for generating AI images, with support for AI video and some AI 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, and ACE-Step is listed for audio. The Generate tab is intended for beginners, while a Comfy Workflow tab exposes a raw graph for advanced users. SwarmUI can install ComfyUI and use it as a backend, and it also supports AUTOMATIC1111 as a backend. Users can build extensions and custom node packs, and the project names an image editor, automatic workflow generation, and Grid Generator among its tools. 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. The maker also points to a free Google Colab option and templates for Runpod and Vast.ai. The README describes the project as being in “Almost-Release” status.
