Flows consist of components that represent individual steps in your application's workflow.</p>

<p>Langflow's drag-and-drop interface allows you to create complex AI workflows without writing extensive code.

You can connect different resources, including prompts, large language models (LLMs), data sources, agents, MCP servers, and other tools and integrations.</p>

<p>When building a <a href="/concepts-flows">flow</a>, you primarily interact with the workspace.
|

This is where you add <a href="/concepts-components">components</a>, configure them, and attach them together.</p>

<p>If your flow has a <strong>Chat Input</strong> component, you can use the <strong>Playground</strong> to run your flow, chat with your flow, view inputs and outputs, and modify the LLM's memories to tune the flow's responses in real time.</p>
|
||
<p>To try this for yourself, create a flow based on the <strong>Basic Prompting</strong> template, and then click <svg xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round" class="lucide lucide-play" aria-hidden="true"><polygon points="6 3 20 12 6 21 6 3"></polygon></svg> <strong>Playground</strong> when editing the flow in the workspace.</p>

|
||
<p>If you have an <strong>Agent</strong> component in your flow, the <strong>Playground</strong> displays its tool calls and outputs so you can monitor the agent's tool use and understand the reasoning behind its responses.
|
||
To try an agent flow in the <strong>Playground</strong>, use the <strong>Simple Agent</strong> template or the <a href="/get-started-quickstart">Langflow quickstart</a>.</p>
