Forge vs Fooocus: choose your control budget

Not universally. Forge is the stronger candidate when you need visible model, sampling, ControlNet and memory decisions. Fooocus is the stronger candidate when a prepared SDXL prompt-and-image workflow removes decisions you do not want to manage.

Start with Fooocus if the goal is a first SDXL image and guided built-in edits with minimal setup choices. Start with Forge if learning the model files and generation parameters is part of the goal, or if a required non-SDXL family rules Fooocus out.

For its intended SDXL path, usually fewer decisions are visible before generation. That does not make every task easier: Advanced settings, first-use downloads and unsupported model families can move the complexity elsewhere.

The UI name alone cannot answer that. Compare model and VAE hashes, effective prompt after expansion/styles, sampler, scheduler, steps, guidance, seed, dimensions and post-processing. We did not run a controlled GPU quality test for this page.

No universal winner is claimed. Measure cold start, model load, first generation and warm repeats on the same machine with the same supported SDXL model, dimensions, batch and runtime. Include setup and editing time if workflow speed is the real question.

That depends on hardware, runtime, model, refiner, precision, offload, dimensions and the chosen task. Forge exposes more memory decisions; exposure is not proof of a lower peak. Record VRAM and system-memory spill locally.

Both are credible SDXL candidates with different operating models. Fooocus is entirely centered on an opinionated SDXL experience. Forge supports SDXL inside a broader WebUI-shaped model and control surface. Run the same checkpoint in both, then run Fooocus defaults as a separate trial.

The original lllyasviel/Fooocus README says the project is built entirely on SDXL, is in limited LTS and has no current plans for newer model architectures. It recommends alternatives including WebUI Forge for FLUX. Do not use a Fooocus fork as evidence for the original.

Original Fooocus is officially scoped to SDXL, so SD 1.5 is not the supported route described by its current README. Original Forge exposes an sd preset, but the exact checkpoint and workflow still need testing on the pinned commit.

No. The inspected original Fooocus UI exposes sampler, scheduler, guidance, sharpness, performance and model controls under Advanced. Its design automates defaults first; it does not remove every advanced setting.

The official documentation describes an offline GPT-2-based prompt-processing engine used by the Fooocus V2 style. Treat the expanded prompt and selected styles as part of the recipe when comparing or reproducing an output.

Yes. Negative Prompt is available under Advanced in the documented interface. A preset or performance mode can still alter the effective recipe, so record those choices too.

Fooocus offers a guided Inpaint or Outpaint route, directional expansion and Enhance around its own SDXL methods. Forge offers Forge Canvas and a denser img2img/inpaint control surface. Test the complete mask, context, revision and export task.

Choose Forge when you need named ControlNet models, preprocessors, weights and guidance ranges in a WebUI-style unit. Choose Fooocus when its built-in Image Prompt types complete the task without exposing that chain. They are not equivalent interfaces.

The inspected original Fooocus source includes ImagePrompt, PyraCanny, CPDS and FaceSwap types with adjustable stop and weight values in Advanced. Verify required model downloads and licenses before treating the route as portable.

The file may be reusable, but support is not guaranteed by visibility. Match the SDXL base model, trigger text, weight, loader behavior and any style or prompt expansion, then compare a controlled baseline.

They can reference deliberately shared storage, but folder mapping and runtime support must be configured. Start with copies or read-only source storage, verify hashes and keep each application environment separate.

No native settings importer was verified. Preserve the Fooocus preset, config, styles, expanded prompt and image metadata, then map only the task-relevant settings into Forge. Some prepared behavior has no one-to-one control.

Both official repositories are under lllyasviel, and the Fooocus README points users to WebUI Forge for newer models. They remain separate applications with different code, licenses, scopes, downloads and update histories.

Its current README states limited long-term support with bug fixes only. The latest inspected main commit is 2 September 2025 and changes CI configuration; the latest published release is v2.5.5 from 12 August 2024. Read those facts together.

A raw latest-commit date is misleading here. Fooocus main is later because of a CI dependency bump, while its product scope is explicitly limited LTS. Forge main last changed in June 2025. Neither fact decides whether your exact workflow works.

Both are local applications, and Fooocus explicitly describes itself as offline. Initial packages, models, inpaint files, extensions or optional components can still require downloads. Verify first-run traffic and the completed local environment yourself.

Only if Forge solves a named limit—such as a required model family, explicit conditioning chain or resource control—and repeats the whole job reliably. Keep Fooocus intact until Forge passes the receipt. Keeping both for different jobs is a valid result.
