The Stable Horde now supports V2.0 for everyone, even anonymously! https://stablehorde.net/
Stable Diffusion 2.0 on the stable horde doesn't need a GPU. Just run on a webclient.

or a local client without install: https://dbzer0.itch.io/lucid-creations
To allow everyone to experiment on SD2.0, we have upped the maximum resolution anonymous accounts can fulfill to 768x768, so remember to use that.
