## How each alternative compares with Stable Diffusion

- **Midjourney** (Paid, $10/mo, checked 2026-11-11): Midjourney Basic lists about 200 image jobs a month (four images each) with general commercial terms, as a hosted service with no model weights to download. Switch if you want polished stylised images from a hosted service without installing models or owning a GPU. Stay with Stable Diffusion if you want weights you can run locally, fine-tune and extend with community tools.
- **Krea AI** (Free plan + paid, $9/mo, checked 2026-11-11): Krea's free plan lists 100 units a day with access to all image models, and Basic gives 5,000 units a month across image, video and 3D models. Switch if you want one app with many third-party image and video models and a daily free allowance. Stay with Stable Diffusion if you want to run Stable Diffusion weights yourself with no per-image charge.
- **Recraft** (Free plan + paid, $10/mo, checked 2026-11-11): Recraft's free plan allows 3 generations per style per day with public images and no commercial use; Basic adds commercial rights and private generations. Switch if you want custom style libraries and private commercial output for design work. Stay with Stable Diffusion if you want unrestricted local generation under the Community License without public galleries.
- **Ideogram** (Free plan + paid, $15/mo, checked 2026-11-11): Ideogram's Plus plan lists 1,000 priority credits a month, and its free plan gives only weekly slow credits that vary by account. Switch if you want hosted images with readable text and priority credits at a fixed monthly price. Stay with Stable Diffusion if you want local control with LoRA training and ControlNet-style tooling.
- **Black Forest Labs (FLUX)** (Paid, $0.048/image, checked 2026-11-11): FLUX is priced per image via API, from $0.048 for FLUX 3 Image at 1K, and offers open-weights licences from a Builder tier for self-hosting. Switch if you want per-image billing with no subscription, or a newer model family with licensed weights. Stay with Stable Diffusion if you prefer the free Community License and the larger Stable Diffusion tooling ecosystem.
- **Adobe Firefly** (Free, Free plan; paid price not published): Firefly has a free plan with limited daily generations and one concurrent job, with paid plans that share credits across Adobe apps. Switch if you work in Adobe apps and want generation in the same credit system. Stay with Stable Diffusion if you want open weights you can run offline and tune on your own images.
- **Stable Diffusion web UI** (Open source, Free (self-hosted)): This AGPL-3.0 browser front end runs Stable Diffusion checkpoints locally with extensions, whereas Stability's own offering is the model licence and a paid API. Switch if you want a browser interface with extensions for running Stable Diffusion checkpoints on your own GPU. Stay with Stable Diffusion if you want the models and licence from Stability itself or a paid API without managing a UI.
- **ComfyUI** (Open source, Free (self-hosted)): ComfyUI is a GPL-3.0 node-graph interface and backend that chains diffusion models, so one workflow can combine image, upscale and video steps. Switch if you want node-graph workflows that chain image models, upscalers and video steps locally. Stay with Stable Diffusion if you want a single model and licence from Stability with the simplest setup.
- **InvokeAI** (Open source, Free (self-hosted)): InvokeAI is an Apache-2.0 creative engine for Stable Diffusion and Flux models with a unified canvas, a more permissive licence than AGPL web UIs. Switch if you want an Apache-2.0 canvas-style tool for Stable Diffusion and Flux that fits commercial work. Stay with Stable Diffusion if you want the models and Community License directly without an extra application layer.
