ComfyUI

ComfyUI belongs in the database because it has become one of the most important workflow interfaces for people building with generative AI beyond simple prompt boxes. The official site positions it around image, video, audio, and 3D generation through modular workflows and nodes, which makes it much more relevant to builders than consumer-facing art apps. It is especially important because many teams use ComfyUI as a practical layer for chaining together models, pre-processing, post-processing, and reproducible generation logic.

It also deserves inclusion because the pricing picture is specific and should be written accurately. The core product remains fundamentally open source, but the official docs also publish partner-node pricing in credits for hosted and partner model usage, with 211 credits equal to 1 USD. That means ComfyUI should not be described like a normal seat-based SaaS. The honest editorial framing is OSS-first workflow software with an official partner-node pricing surface for managed model access.
