What it is

Casibase is an open-source AI LangChain-like Retrieval-Augmented Generation (RAG) knowledge database that supports various LLMs including OpenAI, Azure, LLaMA, Google Gemini, HuggingFace, Claude, Grok, etc. It offers a web UI and Enterprise SSO.

Casibase stands out as an open-source, multi-provider RAG solution with built-in web UI and SSO support, making it ideal for teams needing flexibility in LLM integration.

When it fits — and when it doesn’t

A good fit for

  • Teams needing to integrate multiple LLM providers in one RAG system

  • Developers looking for an open-source alternative with SSO support

  • Projects requiring a web UI for managing the knowledge base

Look elsewhere if

  • Users who prefer cloud-hosted solutions over self-hosting

  • Teams that require real-time streaming capabilities not supported by RAG architecture
