TL;DR
FlowiseWorkflow Automation · ★ 55.5k
When to choose:
- You want an intuitive visual drag-and-drop canvas for building LangChain/LlamaIndex agents, multi-agent workflows, and RAG pipelines without code.
- You need an embeddable chat widget, API endpoints, and a low-code UI for rapid AI application prototyping.
When to skip:
- You need a long-term actively maintained project; the Flowise repository was archived in August 2026 and reached end-of-life.
- You require code-first, type-safe Python orchestration with deterministic checkpointing; Pydantic AI or Temporal are better choices.
