ComfyUI Without Censorship: How to Run It Offline

Does ComfyUI have censorship? Short answer: no.

AI image generation is booming, but one of the most common questions creators ask is: does ComfyUI have censorship?

The answer: No—ComfyUI itself is uncensored. Unlike platforms that impose strict filters, ComfyUI is a node-based workflow tool that gives you total freedom. You choose which models, extensions, and safety modules to run—or not run.

This freedom means you can use ComfyUI for uncensored AI image generation and even experimental uncensored AI video generation without artificial limits.

In this article, we’ll cover:

How ComfyUI handles censorship (or doesn’t).
How to run ComfyUI completely offline.
Why Promptus is the best way to access an optimized version of ComfyUI, alongside Google’s Gemini 2.5 Flash Image (Nano Banana).

🚫 Does ComfyUI Have Censorship?

By default, ComfyUI does not include any censorship.

The results depend entirely on the models you load—Stable Diffusion checkpoints, LORAs, or custom weights.
If you want moderation, you can add optional nodes like Safety Checker or NudeNet.
But if you don’t add them, ComfyUI will let you generate uncensored AI images and videos with no restrictions.

This is one of the biggest reasons why creators love ComfyUI: it’s an open playground, not a locked-down tool.

🔒 Running ComfyUI Offline

Another major advantage is the ability to run fully offline:

Once installed, ComfyUI runs locally on your machine.
Your prompts, data, and generations stay private—nothing is sent to the cloud.
You don’t even need an internet connection, except to download models the first time.

This makes ComfyUI perfect for users who want private, uncensored AI workflows at home, in studios, or in professional environments.

Frequently Asked Questions

Does ComfyUI have censorship?

ComfyUI itself is a community project with an open-source tool and the generation happens in your local computer. When you use the Promptus local app with ComfyUI, the local generations enforces no built-in restrictions or filters on content creation, giving creators total freedom over their workflows.

Which AI models are uncensored for ComfyUI?

Censorship levels depend entirely on the models you choose to load. To generate uncensored images or videos, you must download open-source, unfiltered checkpoints, custom LoRAs, or specific base weights from repositories like Civitai or Hugging Face.

Does ComfyUI have a built-in safety checker?

By default, ComfyUI does not automatically activate content moderation. However, it gives you the flexibility to install optional nodes—such as a Safety Checker or NudeNet—if your specific project or workflow requires moderation filtering.

Can you run ComfyUI without an internet connection?

Yes. After your initial setup and model downloads, ComfyUI runs 100% locally on your computer. It requires no active cloud connections, meaning your text prompts, source assets, and final generations remain completely private and offline.

What are the hardware requirements to run ComfyUI offline?

Running advanced workflows locally—especially experimental uncensored AI video—requires dedicated hardware. You will need a strong local graphics card (GPU), preferably from NVIDIA, with a high amount of VRAM to safely hold heavy diffusion models in memory.

Is ComfyUI difficult to install manually?

Yes, manual installation can be quite intimidating for beginners. It involves setting up Python environments, handling Git dependencies, and manually organizing directory paths for nodes and custom extensions across command lines. For easy use of ComfyUI, many users are switching to the alternative of Promptus.
