Browser Use headless vs headed mode

Quick answer
Browser Use headless mode runs the browser without a visible UI, ideal for automated tasks and CI environments. Headed mode shows the browser window, useful for debugging and interactive sessions.

VERDICT

Use headless mode for automated, resource-efficient browser tasks; use headed mode when visual feedback or manual interaction is needed.
ModeVisibilityPerformanceUse caseDebugging
HeadlessNo UI, runs in backgroundHigher speed, lower resource useAutomated scripts, CI/CD pipelinesHarder to debug visually
HeadedVisible browser windowSlightly slower, more resource useDevelopment, debugging, demosEasy to observe and interact

Key differences

Headless mode runs the browser invisibly without rendering a UI, optimizing speed and resource consumption. Headed mode launches a full browser window, allowing users to see and interact with the browser during execution. Headless is best for automated workflows, while headed is suited for debugging and manual testing.

Headless mode example

This example uses the browser_use Python package to run a headless Chromium browser that navigates to a page and extracts the title.

python
from browser_use import Agent
import os

async def run_headless():
    agent = Agent(
        task="Visit example.com and get the page title",
        llm=None,  # No LLM needed for simple browsing
        headless=True  # Explicitly enable headless mode
    )
    result = await agent.run()
    print("Page title:", result)

import asyncio
asyncio.run(run_headless())
output
Page title: Example Domain

Headed mode example

This example runs the browser in headed mode, showing the browser window for interactive debugging or observation.

python
from browser_use import Agent
import os

async def run_headed():
    agent = Agent(
        task="Visit example.com and get the page title",
        llm=None,
        headless=False  # Show the browser window
    )
    result = await agent.run()
    print("Page title:", result)

import asyncio
asyncio.run(run_headed())
output
Page title: Example Domain

When to use each

Use headless mode for automated, fast, and resource-efficient browser tasks such as scraping, testing, or scheduled jobs. Use headed mode when you need to visually debug, manually interact, or demonstrate browser automation.

ModeBest forAdvantagesLimitations
HeadlessAutomation, CI/CD, scrapingFaster execution, less resource useNo visual feedback, harder debugging
HeadedDebugging, demos, manual tasksVisual feedback, easier troubleshootingSlower, higher resource consumption

Pricing and access

Browser Use is an open-source Python package that requires no paid plans. Both headless and headed modes are free to use locally. API access depends on the AI LLM provider you integrate for task completion.

Key Takeaways

  • Use headless mode for fast, automated browser tasks without UI overhead.
  • Use headed mode when visual interaction or debugging is required.
  • The browser_use package supports both modes via the headless parameter.
  • Headless mode reduces resource consumption and is ideal for CI/CD pipelines.
  • Headed mode facilitates manual testing and demonstration with visible browser windows.
