Editorial review
FlowiseAI is an open-source, low-code platform designed for visually building and deploying AI agents and chatbots.

The platform supports building single-agent systems and chatbots with features like tool calling and knowledge retrieval (RAG) from various data sources, as well as multi-agent systems with workflow orchestration.

The platform is enterprise-ready, supporting production-scale deployments with options for both cloud and on-premises environments, horizontal scaling, and compatibility with over 100 LLMs, embeddings, and vector databases.
