KoboldCpp is a self-contained local AI inference tool with a built-in web UI. It runs GGUF text, image, and speech models with no installation beyond a single binary, primarily aimed at creative writing and roleplay workflows.
KoboldCpp
Where Ollama optimizes for developer API use, KoboldCpp leans into the browser UI and creative writing features: character cards, story memory, chat templates, and image generation through a built-in Stable Diffusion backend. Everything runs locally and privately. The interface is dense and the configuration surface is wide, which rewards power users but can overwhelm newcomers. Skip it if you want a clean API or a simple chat box; reach for it if you want deep control over text generation and a capable all-in-one local setup.

Why it matters: The network clause is the point. Anyone who runs a modified version as a hosted service has to publish those changes, so the code handling your data stays inspectable. This is why privacy-first projects reach for AGPL.
