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.</p>
|

<p>The visual editor simplifies prototyping of application workflows, enabling developers to quickly turn their ideas into powerful, real-world solutions.</p>

<p>Langflow can help you develop a wide variety of AI applications, such as chatbots, document analysis systems, content generators, and agentic applications.</p>
|
||
<p>Langflow includes several pre-built templates that are ready to use or customize to your needs.</p>
|
||
<h3 class="anchor anchorTargetStickyNavbar_Vzrq" id="create-flows-in-minutes">Create flows in minutes<a href="#create-flows-in-minutes" class="hash-link" aria-label="Direct link to Create flows in minutes" title="Direct link to Create flows in minutes" translate="no"></a></h3>
|
||
<p>The primary purpose of Langflow is to create and serve flows, which are functional representations of application workflows.</p>
|
||
<p>To <a class="" href="/concepts-flows">build a flow</a>, you connect and configure component nodes. Each component is a single step in the workflow.</p>
|
||
<p>With Langflow's <a class="" href="/concepts-overview">visual editor</a>, 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.</p>

|
||
<p>You can use the <a class="" href="/concepts-playground"><strong>Playground</strong></a> 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.</p>
|
||
<p>You can also run individual components to test dependencies in isolation.</p>

|
||
<p>You can use your flows as prototypes for more formal application development, or you can use the Langflow API to embed your flows into your application code.</p>
|
||
<p>For more extensive development, you can build Langflow as a dependency or deploy a Langflow server to serve flows over the public internet.</p>

<p>Langflow provides <a class="" href="/concepts-components">components</a> that support many services, tools, and functionality that are required for AI applications.</p>
|

<p>Some components are generalized, such as inputs, outputs, and data stores.

Others are specialized, such as agents, language models, and embedding providers.</p>
|

<p>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.</p>
