ComfyUI vs InvokeAI vs Fooocus: Local Image UI Guide 2026

Last verified: 2026-06-21.

In short: Choose ComfyUI for node workflows, custom nodes, local API work, and the fastest path to new model workflows. Choose InvokeAI for a polished canvas, galleries, model management, and creative editing. Choose Fooocus when you want the simplest SDXL prompt-to-image path and do not need API automation or a growing workflow system.

This recovery update replaces unsourced performance and hands-on claims with primary-source evidence. The main sources are ComfyUI on GitHub, ComfyUI official docs, ComfyUI Desktop, InvokeAI, InvokeAI on GitHub, Invoke Training, Fooocus on GitHub, and the FooocusPlus repository.

Quick comparison

Methodology and evidence level

This page compares product fit, not measured speed.

• We used official docs, official GitHub READMEs, and project-owned pages.
• We do not claim exact generation times, benchmark wins, live pricing, or live hardware availability.
• We treat third-party forks separately from the original projects.
• Hardware statements are conservative because model, precision, driver, UI, extensions, and workflow graph change memory use.
• If you are choosing hardware, validate with your actual model and workflow before buying.

For hardware context, pair this page with ToolHalla's best local AI image generators guide, Stable Diffusion setup guide, and cloud GPU provider guide.

Choose ComfyUI if you want control and automation

ComfyUI is the best first pick for technical users, pipeline builders, and anyone who wants the image workflow to be inspectable as a graph. The official repository describes ComfyUI as a modular AI creation engine available through desktop, portable, local, and cloud paths. The official docs cover tutorials, built-in nodes, development, custom nodes, local API, and cloud API.

That source profile matches the practical recommendation: choose ComfyUI when you need repeatable workflows, custom node ecosystems, local server integration, or a path to newer model workflows. If your image generation system needs to be part of a product pipeline, ComfyUI is usually the first UI to test.

Limitations: ComfyUI has a learning curve. A node graph is transparent and reusable, but it asks the user to understand the graph. If you mostly want to paint, mask, adjust layers, and keep a gallery, InvokeAI may be less work.

Choose InvokeAI if canvas editing is the job

InvokeAI is the best first pick for artists and operators who care about canvas editing, image boards, galleries, and iteration more than building a graph from scratch. Invoke's own site highlights layer-based canvas editing and a professional creative toolkit. The InvokeAI GitHub repository describes a web-based UI for generating, refining, and iterating on visual media.

InvokeAI also has an adjacent Invoke Training project for Stable Diffusion fine-tuning, LoRA training, and textual inversion. That does not mean every team should train models, but it does make InvokeAI a stronger candidate when custom style or brand imagery is part of the workflow.

Limitations: InvokeAI is less natural than ComfyUI for deeply custom graph pipelines. It is a better creative workspace than a low-level workflow engine. If the project depends on a new model or custom node chain, verify support before standardizing on it.

Choose Fooocus if you want simple SDXL prompting

Fooocus is the simple option. Its README describes offline, open-source image generation focused on prompting and images, with minimal manual tweaking and a 4GB Nvidia minimum. That makes it a good first tool for users who want to generate images locally without learning nodes or canvas systems.

Fooocus is also the easiest recommendation to bound: use it for simple local SDXL-style generation and quick prompt exploration. Do not choose it for API automation, custom pipelines, training, or a long roadmap of model support.

The original project should be separated from forks. FooocusPlus is a community continuation with its own direction. If you want Flux or broader model support in a Fooocus-like UI, evaluate FooocusPlus as a separate project, not as proof that the original Fooocus roadmap covers your needs.

Hardware and cloud testing

All three tools can become GPU-bound depending on model and workflow. Do not buy hardware from a UI comparison alone. If you are testing Flux, SDXL batches, ControlNet-heavy workflows, or upscaling, rent first when possible. A short Vast.ai GPU rental can show whether your workflow needs more memory or only a cleaner setup. If you plan to buy, use searches like RTX 4090 GPU on Amazon only as a starting point and verify seller, warranty, power, cooling, and current price yourself.

Decision guide

Pick ComfyUI when

• You need workflow graphs and repeatable pipelines.
• You want local API integration.
• You expect to install custom nodes.
• You want to evaluate newer model workflows early.
• You are comfortable learning a technical interface.

Pick InvokeAI when

• You want canvas editing, layers, galleries, and a visual creative workspace.
• You prefer a guided web UI over graph-first workflow building.
• LoRA or fine-tuning inside the Invoke ecosystem matters.
• Your users are artists, designers, or content operators.

Pick Fooocus when

• You want the lowest-friction local image generator.
• SDXL-style prompting is enough.
• You do not need API automation.
• You do not want to learn node graphs.
• You understand that forks such as FooocusPlus are separate maintenance bets.

FAQ

Is ComfyUI better than InvokeAI?

For pipelines and graph control, yes. For canvas editing and creative iteration, InvokeAI is often the better first tool. The right choice depends on workflow, not status.

Is Fooocus still worth using?

Yes, for simple local SDXL generation and beginner-friendly prompting. It is not the right choice for API workflows, training, or complex automation.

Which tool should a beginner install first?

If the beginner wants quick local images, Fooocus. If they want to learn a tool that can grow into technical workflows, ComfyUI Desktop. If they think in canvas edits and galleries, InvokeAI.

Which tool should a studio standardize on?

A studio should test ComfyUI for pipeline automation and InvokeAI for artist-facing editing. Many teams can justify both: ComfyUI for repeatable production workflows, InvokeAI for canvas work.
