Cerea

Cerea: Self-hosted chat for OpenAI-compatible endpoints with knowledge bases and coding agents.

Cerea is a self-hosted chat interface for any OpenAI-compatible endpoint. It serves people using models by providing chat, knowledge bases, artifacts, tools, and coding agents on users' machines. It pairs with Pystino to handle organizational accounting, quotas, and gateways. Cerea supports file uploads, web search, sandboxed HTML and React previews, and Python execution in a WebAssembly sandbox. It also features a coding agents panel and remote MCP servers as connectors.
