Langflow vs n8n: No-Code AI Agent Showdown

Langflow and n8n are the top no‑code platforms for building AI agents fast. Choose the right one and stop wasting time on endless trials.

Verdict at a Glance

Platform	Price	Ease of Setup	Mobile Support	Key Features	Best For
Langflow	Free tier, Paid Pro $49/mo	Drag‑and‑drop UI, 5‑minute install	Responsive web UI, no native app	LLM chaining, visual prompt editor, built‑in vector store	AI researchers prototyping LLM pipelines
n8n	Free self‑host, Cloud $20/mo	Node‑based workflow, Docker quick‑start	Responsive UI, iOS/Android via web	200+ integrations, webhook triggers, custom code nodes	Automation engineers needing broad app connectors

Why Visual AI Builders Matter

Speed beats code when you need a proof‑of‑concept. Drag‑and‑drop lets you iterate in minutes, not days.

Both platforms let you connect LLMs, APIs, and data stores without writing a line of Python.

Langflow Deep Dive

Specialized for LLM workflows. Visual prompt editor maps token flow instantly.

• Native LangChain nodes
• Built‑in vector stores (FAISS, Chroma)
• Supports OpenAI, Anthropic, Cohere

When to Pick Langflow

• You need rapid LLM prototyping.
• Vector store and prompt chaining are core.
• Team consists mainly of AI researchers.

When to Pick n8n

• You need to stitch AI with existing business tools.
• Automation beyond AI is a priority.
• Self‑hosting compliance matters.

FAQ

Does Langflow support Azure OpenAI?

Yes, add a custom endpoint in the OpenAI node settings.

Can n8n run on a Raspberry Pi?

Docker image works on ARM; performance is modest but sufficient for testing.

Is there a free vector store in Langflow?

FAISS is bundled free; Chroma requires a paid plan.

How does n8n handle rate limiting for LLM APIs?

Use the built‑in “Throttle” node to queue requests.

Do both platforms offer community templates?

Langflow has a public flow gallery; n8n provides a template marketplace.

Bottom Line

Pick Langflow for pure AI workflow speed, n8n for broader automation needs. Both eliminate coding, but matching the tool to your integration scope saves weeks of wasted evaluation.
