What is MaxKB?

MaxKB (Max Knowledge Brain) is an open-source, self-hostable enterprise AI agent platform developed by FIT2CLOUD.

Built on a LangChain-powered RAG pipeline, it enables organizations to ingest private documents, build intelligent Q&A agents, and automate complex business workflows — all without writing a single line of code.

It supports private model deployment (DeepSeek, Llama, Qwen) and public APIs (OpenAI, Claude, Gemini), making it fully model-agnostic. With over 1 million cumulative downloads and 20K+ GitHub stars, MaxKB is production-verified across healthcare, finance, education, and manufacturing sectors.

Its MCP tool-use support and built-in workflow orchestration engine allow teams to graduate from basic knowledge Q&A to full agentic automation at their own pace.
