An open-source, Python-backed visual builder that uses drag-and-drop to assemble AI agents, retrieval-augmented generation (RAG) applications, and MCP servers. It helps teams avoid vendor lock-in by providing a self-hostable platform for developers, AI teams, and product teams to build, deploy, and iterate on LLM-based agents and RAG workflows.
