Direct answer
What is DiffusionBee?
DiffusionBee is a downloadable macOS application that runs Stable Diffusion locally and offline, allowing users to generate images, edit visuals, and train custom models without sending data to the cloud.
DiffusionBee is a creative AI toolbox designed to run Stable Diffusion entirely on local computer hardware running macOS 13.1 or higher. It executes generative tasks without sending prompts, training data, or rendered images over the internet. The suite includes text-to-image creation, image-to-image modification, generative fill for inpainting and object removal, AI upscaling, and image variation tools. It also provides video generation features, an illusion generator, and control image capabilities for structural composition. An integrated AI canvas combines digital brushwork with prompt-based generation. Furthermore, DiffusionBee supports training custom models locally on user-supplied image datasets to reproduce specific styles, people, or objects. The software is optimized for Apple silicon hardware, though it also runs on Intel-based Macs with variable performance.
DiffusionBee runs completely offline on macOS hardware, ensuring prompts, datasets, and generated images remain entirely on your computer without cloud fees or external servers.

Editorial assessment
Pros and limitations
Where it is strong
- Operates 100% offline, keeping prompts and generated outputs strictly private.
- Free download with no metered credits or recurring subscriptions listed on the site.
- Integrates full image generation, generative fill, upscaling, and model training in one package.
Where to be careful
- Restricted to macOS 13.1 or higher, lacking support for Windows or Linux operating systems.
- Render speeds depend on local hardware, running notably slower on Intel Macs without dedicated graphics.

Frequently asked
DiffusionBee FAQ
Where are the images generated?+
Images are generated locally on your computer. Nothing is sent to the cloud, and your prompts, models, and outputs never leave your device.
How much time does it take to generate an image?+
On an 8GB M1 MacBook Air, DiffusionBee takes approximately 30 seconds to generate an image. Speeds are faster on computers with higher specifications.
Can I freely use the generated images?+
Yes, you can freely use the generated images as long as you comply with the CreativeML Open RAIL-M license.
What are the minimum system requirements for DiffusionBee?+
DiffusionBee requires macOS 13.1 or higher. Machines with Apple silicon processors are recommended for optimal performance.
Does DiffusionBee work with Intel-based machines?+
Yes, DiffusionBee works on Intel-based Macs. However, it runs very slowly compared to Apple Silicon M1 machines if your system lacks a dedicated graphics chip.
