Fooocus

Fooocus is an SDXL-powered image generator with multi-prompt support, A1111-style prompt reweighting, custom aspect ratios, style adjustments, inpainting, and InsightFace face swapping. It runs in the browser, with a Google Colab option and an open source GitHub repository for users who want to self-host.

Fooocus is a browser-based image generator built around the SDXL model family. It pairs a text prompt with a set of style and composition controls, then renders an image that can be refined with inpainting and editing tools. The platform is aimed at artists, designers, and hobbyists who want more control than a single-click generator offers without managing a local Stable Diffusion install. In practice, a session starts with a prompt or an image prompt. Fooocus supports multiple prompts at once, so you can merge several creative directions in one generation, and it uses A1111's reweighting algorithm to shift emphasis toward or away from specific terms. Style controls cover contrast, sharpness, and color, while aspect ratio settings let you target a specific layout. When the output needs work, a proprietary inpainting routine fills, completes, or replaces regions of the image, and InsightFace powers face swapping for avatars and portrait edits. The tool also supports a broad range of SDXL models, which means outputs can swing from painterly and illustrative to photorealistic depending on the preset selected. Users who want to run the same generator outside the hosted app can launch it on Google Colab or install it from the GitHub repository, which makes Fooocus a middle ground between fully hosted commercial generators and self-managed Stable Diffusion setups. The people most likely to benefit are digital artists iterating on concepts, designers producing mood boards and avatars, and instructors demonstrating image generation in a classroom. The hosted version removes installation work, while the open source route keeps the door open for users who prefer local control.
