Invoke AI

InvokeAI is an open-source generative AI creative engine built on Stable Diffusion, designed for artists, designers, and content creators who need professional-grade AI image generation tools. The platform features an industry-leading WebUI with layer-based canvas editing, node-based workflow composition, support for Stable Diffusion, SDXL, and other generative models, and is fully self-hosted under an Apache 2.0 license. InvokeAI began as a community open-source project and was later backed by a commercial entity that subsequently shut down its hosted service when the founding team joined Adobe; the open-source project continues under community maintainers Lincoln Stein and Vic (Blessedcoolant).
