# Langflow

> Langflow (v1.12.7, October 2026) is a Python platform for building AI agents and LLM workflows on a visual canvas. Each flow can be called as an API, triggered by a webhook or served as an MCP tool, and components can be edited in Python. It supports the major model providers and local models through Ollama. Install the Langflow Desktop app on Windows or macOS, the Python package (Python 3.10 to 3.14), or Docker. MIT licensed. It is an AI workflow builder, not a library of ready-made app-to-app connectors like Zapier.

## What it replaces
- Zapier: AI agent workflows, Webhooks (partial). Strong for AI agent flows and webhook triggers; far fewer ready-made app integrations and no documented scheduler.
  - Use it instead of paying for Zapier? Personal use: Yes. Business: Yes.
- Make: AI agent workflows, Webhooks (partial). Visual canvas focused on LLM agents and retrieval rather than general app-to-app automation.
  - Use it instead of paying for Make? Personal use: Yes. Business: Yes.
- ChatGPT Plus: Chat with your documents (partial). You build the file-chat flow yourself from a template and bring your own model, cloud or local.
  - Use it instead of paying for ChatGPT Plus? Personal use: Yes. Business: Yes.
