Stable Diffusion web UI (AUTOMATIC1111)
Classic Gradio web interface for Stable Diffusion with txt2img, img2img, inpainting, upscaling and a large extension ecosystem.
Quick answer
Stable Diffusion web UI (AUTOMATIC1111) is a classic Gradio web interface for Stable Diffusion with txt2img, img2img, inpainting, upscaling and a large extension ecosystem, listed under Image & media generation. A typical small-business use: generate product shots, banners and social images in-house with your own checkpoints. It needs a GPU server; we do not estimate that cost because GPU prices vary too much by card and provider. License: AGPL-3.0, which allows internal business use. Activity is low: the last commit was on Jul 27, 2024.

What is Stable Diffusion web UI (AUTOMATIC1111)?
Stable Diffusion web UI, usually called AUTOMATIC1111 or A1111, is a browser interface for running Stable Diffusion checkpoints locally. It covers text-to-image, image-to-image, inpainting and outpainting, upscalers, prompt styles, LoRA and textual-inversion embeddings, and an HTTP API, and has one of the largest collections of community extensions. It installs with a launch script that sets up Python dependencies; models are downloaded separately. Development has slowed, with the last code push in March 2026.
Where it fits in a 10–200 person business
- Generate product shots, banners and social images in-house with your own checkpoints
- Inpaint or outpaint existing marketing images to fix or extend them
- Batch image variations or upscaling through the built-in API
These use cases are our editorial suggestions, not claims made by the project.
Can a business use Stable Diffusion web UI (AUTOMATIC1111)? (license)
| License | AGPL-3.0 |
|---|---|
| Type | Network copyleft (AGPL): Like GPL, and also applies when users access a modified version over a network. |
| Internal business use | Allowed under the license text |
| What to watch | Free for internal and commercial use. If you modify it and let users interact with it over a network, you must offer them the modified source under AGPL-3.0. Each model checkpoint has its own license; check it before commercial use. |
This is a plain-English summary of the license text, not legal advice. Third-party models you run with it have their own licenses.
Data & compliance: does Stable Diffusion web UI (AUTOMATIC1111) phone home?
| Telemetry (usage data sent to the vendor) | Not documented |
|---|---|
| Other calls home by default (updates, marketplaces, default cloud services) | Not documented |
| Single sign-on (OIDC / SAML / LDAP) | Not documented |
| Audit log | Not documented |
| Role-based access control (RBAC) | Not documented |
| Data residency / GDPR notes from the project | Not documented |
Checked against the project's own docs and repository on . "Not documented" means we could not find the answer in official sources; it does not mean the feature is missing or that no data is sent. Third-party services you connect (model APIs, vector databases, search engines) have their own data policies. Compare all apps.
What hardware does Stable Diffusion web UI (AUTOMATIC1111) need?
The project does not publish a minimum CPU/RAM figure, so we leave the official value blank rather than guess.
GPU: NVIDIA GPUs are the recommended path; AMD GPUs, Intel CPUs/GPUs, Apple Silicon and Ascend NPUs have separate install guides. With little VRAM use --medvram or --lowvram; without enough VRAM it may refuse to launch or run out of memory.
No CPU, RAM, VRAM or disk minimum is published; the wiki says required VRAM depends largely on image resolution. Requires Python 3.10.6 (or 3.11 on very new systems) and git.

How much does it cost to host Stable Diffusion web UI (AUTOMATIC1111) per month?
Needs a GPU server for practical use. Not estimated, because GPU prices vary too much by card and provider.
How to deploy Stable Diffusion web UI (AUTOMATIC1111)
Method: Launch script (Linux)
sudo apt install wget git python3 python3-venv libgl1 libglib2.0-0
git clone https://github.com/AUTOMATIC1111/stable-diffusion-webui
cd stable-diffusion-webui
./webui.sh
# options go in webui-user.sh; UI on http://127.0.0.1:7860From the official instructions: github.com/AUTOMATIC1111/stable-diffusion-webui#automatic-installation-on-linux. Always check the source for the current version before you run it.
Known gotchas when self-hosting Stable Diffusion web UI (AUTOMATIC1111)
- The UI listens only on localhost by default. --listen opens it to the network and --share publishes a public gradio.live link; add --gradio-auth username:password before doing either. source
- Python 3.10.6 is the documented version; the README warns newer Python versions do not support its torch build, so very new distros need python3.10 or 3.11 installed alongside. source
- Without enough VRAM the web UI may refuse to launch or fail with out-of-memory errors. --medvram or --lowvram cut VRAM use at the cost of speed; needs grow with image resolution. source
- Development has slowed: the last release is v1.10.1 (July 2024) and the master branch has not changed since then; newer commits land only on the dev branch (latest March 2026). Expect slow support for new model families. source
