Sogni vs SwarmUI

Sogni is an AI image-generation service with text-to-image creation, reference-image support, image editing, and API access. It supports PNG, JPG, and WebP output, and commercial use is included with Sogni Unlimited. The Free plan offers unlimited on-device rendering on Mac and iOS, more than 150 open-source models locally, free monthly Spark for filtered Supernet jobs, basic Supernet cloud rendering, and limited API access. Premium Spark costs $1.99 a month and provides pay-as-you-go Spark credits, a priority queue, and access to supported premium and partner models, with no monthly commitment. Sogni Unlimited costs $20 a month and includes credit-free fair-use Supernet rendering for supported open-weight models, full SDK and API access, up to four concurrent image jobs, and a three-day free trial. Unlimited Pro costs $50 a month and allows up to 16 concurrent image jobs, with higher-priority queue placement and a larger media queue. Enterprise has custom pricing, dedicated Supernet capacity, custom rate limits and SLA, and team account management.

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.
