Which one is for you
Pick DiffusionBee if
- Fits if you have an Apple silicon Mac and want to make images free and offline
- Works for people who would train a small custom model on their own pictures
Look elsewhere if
- Skip it if you use Windows, Linux or a phone, since only macOS is offered
- Tight if you have an Intel Mac, which the FAQ calls very slow without a dedicated graphics chip
- Tight if you have an 8GB Mac, where one image takes about 30 seconds
- Watch out: generated images are tied to the CreativeML Open RAIL-M license
Pick Stability AI if
- Fits if you're a developer adding image generation and editing to your own app
- Works for teams who can run open image models on their own hardware or call them on Bedrock or Azure
Look elsewhere if
- Skip it if you just want to type a prompt and get a picture, as there's no app; Start creating leads to enterprise partnerships
- Not for you if your company makes over $1M a year, as that needs an Enterprise License priced by sales
- Too light for developers who want video by API, as the price list has none; Stable Video Diffusion is self-host only
- Watch out: the API is pay per use at a cent a credit, 2.5 to 8 credits an image and 60 for the Creative Upscaler
- Tight if you have no hardware of your own, as the free license means running the models yourself, and the API start is 25 credits
How we grade them
| 2.8GPADiffusionBeeGood | 1.8GPAStability AIWeak | |
|---|---|---|
| Value for money | AThe whole app is free and runs locally on your Mac, which counts as free and substantial. No paid plans are listed on the site. | CNothing a person can subscribe to. The models are free to run yourself under $1M yearly revenue, which takes your own hardware, and the API charges $0.025 to $0.08 an image at a cent a credit. There's no plan to set against this category's. |
| Free plan and trial | AFree outright, with no paid plan listed and no cap beyond how fast your Mac is. | CThe Community License lets people and companies under $1M a year run the core models free, commercial use included. That needs your own hardware, and the API's free start is 25 credits. |
| Features | CText to image, image to image, generative fill, upscaler, variants, local training and video tools. A local Stable Diffusion app, with output tied to the CreativeML Open RAIL-M license. | DBuilding blocks only: SD 3.5 models, editing, upscaling, sketch and style control, and 3D. There's no app for a person, and the image page's Start creating link goes to enterprise partnerships, so it needs code or another product to be useful. |
| Ease of use | BNo store rating on record. You download it and start generating, with nothing to set up, though Intel Macs are very slow. | DNo app and no rating. Using it means calling an API from code or running the models on your own hardware. |
| Platforms and integrations | DmacOS only, version 13.1 or later. No Windows, Linux, phone, web or API is listed. | BAn API plus the models on Amazon Bedrock, SageMaker JumpStart and Microsoft Azure AI Foundry, and downloads for your own machines. No phone or desktop app. |

More comparisons
How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
