Flowise

Flowise is an open source, low-code/no-code platform for building generative AI applications, including AI agents, chat assistants, and LLM orchestration flows. It provides modular building blocks for constructing systems ranging from simple compositional workflows to autonomous agents, addressing the need to assemble and iterate on customized LLM pipelines without extensive coding.

Key capabilities include Agentflow for multi-agent systems with workflow orchestration, Chatflow for single-agent systems and chatbots with tool calling and retrieval-augmented generation (RAG), and Human in the Loop for human review of agent tasks. Observability features provide execution traces with support for Prometheus and OpenTelemetry. Developers can extend and integrate via APIs, TypeScript and Python SDKs, and an embedded chat widget. The platform supports over 100 LLMs, embeddings, and vector databases, with both cloud and on-premises deployment and horizontal scaling through message queues and workers.

Flowise is packaged as a free plan with limited flows, assistants, predictions, and storage, alongside paid Starter and Pro editions that add higher usage limits, storage, workspaces, users, admin roles, and priority support. The Pro edition is seat-based with additional per-user costs. An open source community edition is also available.
