sdnext

What it does

A mature all-in-one WebUI and server for generative imaging: Stable Diffusion plus dozens of other architectures, with refinement, captioning, upscaling and video in the same place, actively maintained and cross-platform. The breadth costs you an afternoon of setup and vocabulary, so if you only want a picture there are gentler options. Model licences vary independently of the app's Apache-2.0 — check the model before using output commercially.

sdnext FAQ

Is sdnext free?

Yes. It runs on your own machine, so there is no usage-based cost either.

Do I need to install anything or write code to use sdnext?

It needs the command line. If you are not comfortable typing commands, expect to get stuck during setup.

Does sdnext work on a phone?

No. It needs a computer.

Can I use sdnext commercially?

The licence is Apache-2.0, which permits commercial use. Conditions such as keeping the copyright notice still apply, so read the licence text before shipping it inside something.
