Langflow
78.9
LangGraph
77.4Choose Langflow when you need engineers and technical teams seeking a visual yet code-extensible canvas to build, evaluate, and deploy agentic RAG systems.. Choose LangGraph when you need building complex, custom, and multi-actor agent workflows that require explicit state management, human approvals, and real-time streaming.
At a glance
The practical differences
| Decision factor | Langflow | LangGraph |
|---|---|---|
| Best for | engineers and technical teams seeking a visual yet code-extensible canvas to build, evaluate, and deploy agentic RAG systems. | building complex, custom, and multi-actor agent workflows that require explicit state management, human approvals, and real-time streaming |
| Not ideal for | non-technical marketers looking for a no-code plug-and-play chatbot builder without understanding data pipelines or APIs. | non-technical users looking for no-code bot builders or projects requiring only basic, linear LLM call chains |
| Pricing | As of September 2026, Langflow offers open-source self-hosting and a free cloud account option, alongside paid Professional Services and Premier Support. Specific commercial tier pricing is not published on the main page, so check the official website for current terms. | At the review date, the LangGraph orchestration library is open source under an MIT license and free to use. Optional hosted infrastructure, tracing, and managed deployment through LangSmith offer a free Developer tier (1 seat, 5,000 monthly traces) and a paid Plus tier at $39 per seat per month plus compute and storage usage. |
| Key difference | Unlike closed-box builder tools, Langflow exposes full Python code under every component and allows developers to convert entire visual flows into callable APIs or MCP servers. | Unlike generic black-box autonomous loops, LangGraph models agent workflows as explicit stateful graphs with fine-grained control over cyclical transitions, state persistence, and human-in-the-loop interruptions. |
| Overall rank | #49 | #88 |
| Review verdict | Langflow suits software engineers and AI developers who want to prototype and deploy RAG flows and autonomous agent teams rapidly without losing code-level control. It is less suited for non-technical business users seeking turnkey chatbot widgets with zero configuration. | LangGraph suits software engineers who need precise, low-level control over multi-agent workflows, state persistence, and human approval steps. It is not designed for non-technical users seeking no-code drag-and-drop builders or teams that only need standard, non-cyclical prompt chaining. |
