The short answer
Three visual agent builders dominate 2026: n8n (199,396 stars) is the workflow-automation king with 400+ integrations - agents as part of bigger pipelines. Dify (151,406 stars) is the LLM-app platform: RAG, prompt studio, agent mode, API publishing. Langflow (152,859 stars) is the most developer-friendly - a visual canvas that maps 1:1 to LangChain components.
Which one for which job
| Tool | Stars | Sweet spot | Best for |
|---|---|---|---|
| n8n | 199,396 | Automation workflows | Zapier replacement + AI steps |
| Dify | 151,406 | LLM apps & RAG | Chatbots, knowledge bases, APIs |
| Langflow | 152,859 | Agent prototyping | LangChain users, complex agents |
30-minute starter: n8n AI agent
- Install:
docker run -d -p 5678:5678 n8nio/n8n- open http://localhost:5678 - Add an "AI Agent" node with an LLM (Ollama/OpenAI) and a tool (e.g., HTTP Request).
- Wire a trigger: Webhook, Slack message, or schedule.
- Activate the workflow - the agent runs on every trigger.
Dify's edge
- Built-in RAG pipeline: upload docs, chunk, embed, retrieve - all visual.
- One-click publish as API for your own apps.
- Prompt management with versioning - team-friendly.
Real numbers
- n8n runs 100k+ self-hosted deployments and has an active paid cloud too.
- Dify is used by 1M+ developers for LLM apps (per its site) with 151k GitHub stars.
- Langflow generates exportable Python from the canvas - bridge to real code.
FAQ
Q: Do they work with local models? A: Yes - all three connect to Ollama (177,825 stars) or any OpenAI-compatible endpoint.
Q: Which has the gentlest learning curve? A: Dify - the LLM-app templates do most of the setup. n8n assumes you know workflow concepts.
Q: Can I export my n8n workflow to code? A: Not directly, but Langflow exports Python, and n8n workflows are JSON you can version-control.
