civitai

Why we included this project

Civitai is the open-source codebase behind one of the largest community hubs for Stable Diffusion models and the custom assets people build around them. It's a full Next.js application for standing up your own platform where creators upload and trade checkpoints, textual inversions, hypernetworks, VAEs, and other customizations, with account creation, model browsing, and comment-based collaboration all built in. Because it's a large, production-oriented web app rather than a lightweight library, it fits teams comfortable running a multi-service setup with Postgres, tRPC, and object storage. For developers it also works as a useful reference for building a sizable Next.js community site with Prisma and a typed API layer. Just expect an involved self-hosting effort, since generation, training, and real-time chat all depend on external services.
