InvokeAI
Walks through the path from prompt to finished image in a locally hosted setup, showing what layer editing, inpainting and batch generation each take off your hands, and what the open-source licence asks in return.
Invoke, also written InvokeAI, is an open-source image engine built around local self-hosting. Prompting, inpainting, outpainting and layer compositing sit in one professional interface, while models stay on the machine that runs them. Released under Apache 2.0, it supports batch generation and parameter comparison; after the hosted service closed, core contributors kept the community edition running.
