Stable Diffusion alternatives
The 8 closest alternatives to Stable Diffusion, which is open source. Each one below does roughly the same job from a different angle.
Why people move off Stable Diffusion
- Requires technical setup that casual users will find intimidating
- Output quality out-of-the-box is below Midjourney without custom models
- Stability AI as a company has had significant instability and leadership churn
- SD3 release was controversial and underperformed initial expectations
Worth weighing against what it does well: completely free to run locally on your own hardware
