Human in the loop

Let a human interact with the live browser while the agent is running. Useful for approvals, payments, complex auth flows, or reviewing agent work before continuing.

Use cases

• Human enters payment info or approves a transaction, agent handles the rest
• Human navigates a complex auth flow, then hands back to agent
• Human reviews what the agent did before the agent continues

Sessions time out after 15 minutes of inactivity. The maximum session duration is 4 hours. If the human needs more time, send a lightweight follow-up task (e.g. “wait”) to reset the inactivity timer.

Flow

1. Create a session — it stays alive automatically when you pass session_id to run()
2. Run an agent task
3. Human interacts with the live browser
4. Send a new follow-up task

Python

from browser_use_sdk.v3 import AsyncBrowserUse

client = AsyncBrowserUse()

# 1. Create a session
session = await client.sessions.create()
print(f"Live view: {session.live_url}")

# 2. Agent does the first part
result = await client.run(
    "Go to amazon.com and search for noise cancelling headphones",
    session_id=session.id,
)
print(result.output)

# 3. Human opens live_url and picks a product
input("Press Enter after you've selected a product in the live view...")

# 4. Agent continues where the human left off
result = await client.run(
    "Get the details of the selected product — name, price, and rating",
    session_id=session.id,
)
print(result.output)

# Clean up
await client.sessions.stop(session.id)

import { BrowserUse } from "browser-use-sdk/v3";
import * as readline from "readline";

const client = new BrowserUse();

// 1. Create a session
const session = await client.sessions.create();
console.log(`Live view: ${session.liveUrl}`);

// 2. Agent does the first part
const searchResult = await client.run(
  "Go to amazon.com and search for noise cancelling headphones",
  { sessionId: session.id },
);
console.log(searchResult.output);

// 3. Human opens liveUrl and picks a product
const rl = readline.createInterface({ input: process.stdin, output: process.stdout });
await new Promise((resolve) =>
  rl.question("Press Enter after you've selected a product in the live view...", resolve),
);
rl.close();

// 4. Agent continues where the human left off
const result = await client.run(
  "Get the details of the selected product — name, price, and rating",
  { sessionId: session.id },
);
console.log(result.output);

// Clean up
await client.sessions.stop(session.id);
