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.
