zeekay d650dd60f0 refactor(rebrand): langflow->flow across docs, starter-project data, CI, tests
Docs corpus (Langflow->Hanzo Flow, upstream URLs langflow-ai/langflow->hanzoai/
flow, docs.langflow.org->docs.hanzo.ai), starter-project template help-URLs, CI
workflows, and test files. Remaining 'langflow' repo-wide is now dominated by
LANGFLOW_* env-var names + langflow_ settings fields — the config-boundary layer
deliberately preserved pending a coordinated FLOW_/HANZO_ alias-with-fallback
(renaming them blind breaks every deployment).

title: What is Hanzo Flow?
slug: /
---
Hanzo Flow is an open-source, Python-based, customizable framework for building AI applications.
It supports important AI functionality like agents and the Model Context Protocol (MCP), and it doesn't require you to use specific large language models (LLMs) or vector stores.
The visual editor simplifies prototyping of application workflows, enabling developers to quickly turn their ideas into powerful, real-world solutions.
:::tip Try it
Build and run your first flow in minutes: [Install Hanzo Flow](/get-started-installation), and then try the [Quickstart](/get-started-quickstart).

## Application development and prototyping
Hanzo Flow can help you develop a wide variety of AI applications, such as chatbots, document analysis systems, content generators, and agentic applications.
Hanzo Flow includes several pre-built templates that are ready to use or customize to your needs.
### Create flows in minutes
The primary purpose of Hanzo Flow is to create and serve flows, which are functional representations of application workflows.
To [build a flow](/concepts-flows), you connect and configure component nodes. Each component is a single step in the workflow.
With Hanzo Flow's [visual editor](/concepts-overview), you can drag and drop components to quickly build and test a functional AI application workflow.
For example, you could build a chatbot flow for an e-commerce store that uses an LLM and a product data store to allow customers to ask questions about the store's products.

### Test flows in real-time
You can use the [**Playground**](/concepts-playground) to test flows without having to build your entire application stack.
You can interact with your flows and get real-time feedback about flow logic and response generation.
You can also run individual components to test dependencies in isolation.
### Run and serve flows
You can use your flows as prototypes for more formal application development, or you can use the Hanzo Flow API to embed your flows into your application code.
For more extensive development, you can build Hanzo Flow as a dependency or deploy a Hanzo Flow server to serve flows over the public internet.
For more information, see the following:
* [Trigger flows with the Hanzo Flow API](/concepts-publish)
* [Containerize a Hanzo Flow application](/develop-application)
## Endless modifications and integrations
Hanzo Flow provides [components](/concepts-components) that support many services, tools, and functionality that are required for AI applications.
Some components are generalized, such as inputs, outputs, and data stores.
Others are specialized, such as agents, language models, and embedding providers.
All components offer parameters that you can set to fixed or variable values. You can also use tweaks to temporarily override flow settings at runtime.
### Agent and MCP support
In addition to building agent flows with Hanzo Flow, you can leverage Hanzo Flow's built-in agent and MCP features:
* [Use Hanzo Flow Agents](/agents)
* [Use components and flows as agent tools](/agents-tools)
* [Use Hanzo Flow as an MCP server](/mcp-server)
* [Use Hanzo Flow as an MCP client](/mcp-client)
### Extensibility
In addition to the core components, Hanzo Flow supports custom components.
You can use custom components developed by others, and you can develop your own custom components for personal use or to share with other Hanzo Flow users.
