Civitai
A self-hostable AI model-sharing platform for Stable Diffusion assets, with uploads and comments; its public website also offers hosted art creation.

Civitai is a platform for creators to share AI image models, browse other people's work and exchange feedback. You can self-host its model-sharing platform, but image generation and training don't work in the local setup.
- Model discovery: Browse Stable Diffusion and Flux models on the public site, including free models, to find assets for AI image creation.
- Model sharing: Create an account and upload models or Stable Diffusion customization assets, including textual inversions, hypernetworks, VAEs and aesthetic gradients.
- Comments and feedback: Discuss shared models with other users and give creators feedback on their work.
- Community artwork: Browse images, videos, articles and comics alongside creator pages to see what people make with AI models.
- Hosted art creation: The public website lets you create and share AI art; generation runs through external services and isn't available in a local copy of the platform.
The platform is open source under Apache 2.0. A self-hosted copy runs with Node.js and Docker-backed services. Chat, notifications, other live updates and Buzz also depend on services that aren't available in the local setup.
