Browser-use:基于 Python 的智能浏览器自动化 AI 工具调研与实战
一、概述
Browser-use 是一个旨在将 AI "智能体"(Agents)与真实浏览器进行交互的 Python 库,可以轻松实现浏览器自动化。在配合 LLM(如 GPT 系列)使用时,浏览器-use 能够让你的智能体发起对网页的访问、操作页面元素、收集信息、执行脚本等,从而扩展 AI 应用的落地场景。
- GitHub : browser-use/browser-use
- 官网 : browser-use.com
- 文档 : docs.browser-use.com
目前 Browser-use 最低需要 Python 3.11 及以上,才能正常使用其封装的 Playwright 功能。
1. 技术栈:
- LangChain(AI Agent框架)
- Playwright(浏览器自动化)
- dotenv(环境变量 key)
- 异步I/O架构
2. 流程图
browser-use:语言模型 -> 决策/控制 -> 浏览器执行 -> 数据回传 -> 模型后处理
二、核心特性
1. 简单的 Agent 接口
通过 Agent 类即可快速创建带浏览器交互能力的智能体,赋能 LLM 与网页之间的复杂操作。
python
agent = Agent(
task="打开 https://cn.vuejs.org/guide/essentials/computed,获取页面里所有的 h2 标签文本及所有的 a 标签文本(以及它的 href)",
llm=llm,
)
result = await agent.run()
2. 多语言模型支持
可轻松集成 LangChain 提供的各类 LLM(如 OpenAI、Anthropic、Cohere 等)进行高级任务管理。
模型 | 所属/类型 |
---|---|
GPT-4o | OpenAI |
Claude | Anthropic |
Azure | Azure OpenAI |
Gemini | Google Generative AI |
DeepSeek-V3 | DeepSeek |
DeepSeek-R1 | DeepSeek |
Ollama | 本地模型 (需安装 Ollama) |
3. 基于 Playwright
默认使用 Playwright 进行浏览器的无头启动、页面操作和渲染控制;对常见网页交互场景提供友好的抽象。
4. 云端版 & 本地版
除了本地安装运行外,Browser-use 也提供托管版本,可以直接在云端执行,无需配置本地环境。
三、安装与环境配置
1. Python 版本
- 需要 Python 3.11 或更高版本。
- 推荐在独立虚拟环境(venv)或管理工具(如 uv)中配置环境。
1.1. 推荐使用 pyenv 管理 python
Github:github.com/pyenv/pyenv
shell
brew install pyenv
pyenv install 3.11.9
shell
# pyenv 根目录
export PYENV_ROOT="$HOME/.pyenv"
export PATH="$PYENV_ROOT/bin:$PATH"
# 初始化
eval "$(pyenv init -)"

2. 安装方法
2.1. 安装 browser-use
powershell
pip3 install browser-use
2.2. 安装 Playwright
powershell
playwright install
- 此操作会自动下载 Chromium 无头浏览器,用于后续的浏览器自动化。
2.3. 配置 LLM API Keys(可选)
- 在 .env 文件中填写相应的 OPENAI_API_KEY=、ANTHROPIC_API_KEY= 等 Key。
plain
OPENAI_API_KEY=sk-xxxxxxx
- 如果使用其他 LLM,需要参考 LangChain 文档或对应服务提供的说明进行配置。
四、基础配置
1. Agent
1.1. Agent 参数
参数名称 | 类型 | 默认值 | 说明 |
---|---|---|---|
task | str | 无 | 代理需要执行的任务描述。(必传) |
llm | BaseChatModel (LangChain Model) | 无 | 主语言模型,执行对话和工具调用。(必传) |
controller | Controller 实例 | 默认 Controller | 自定义函数/工具调用的注册表 |
use_vision | bool | True | 是否启用视觉能力(截图+分析)。如模型支持图像输入,可显著提高网页理解;也会产生额外 token 成本。 Deepseek 需要设置为 False |
save_conversation_path | str | 无 | 若指定,则会将对话历史保存在该路径下,用于调试或审计。 |
system_prompt_class | type (自定义 System Prompt 类) | 默认Prompt | 自定义系统提示词逻辑 |
browser | Browser (Browser-use 实例) | 无 | 重用已创建的 Browser 实例;若不提供,则 Agent 每次 run() 时会自动创建并关闭新的浏览器。 |
browser_context | BrowserContext (Playwright 实例) | 无 | 使用已有的浏览器上下文 (Context)。适合需要维护持久会话 (cookies/localStorage) 的场景。 |
max_steps | int | 100 | 允许 Agent 执行的最大步骤数,防止死循环或无限操作。 |
planner_llm | BaseChatModel | __ | 规划用语言模型,与主 LLM 分开;可用较小/便宜模型处理高层策略。 |
use_vision_for_planner | bool | True | Planner 是否能使用视觉功能(若主 LLM 已开启视觉,这里可独立关闭以节省资源)。 |
planner_interval | int | 1 | Planner 模型执行间隔。即每多少步调用一次 Planner 作重新规划。 |
message_context | str | 无 | 额外的任务/上下文信息,辅助 LLM 更好理解或执行任务。 + 03/28 文档已删除字段 |
initial_actions | list[dict] | 无 | 初始化时要执行的动作列表(无需经 LLM 调用),格式为 {action_name: {...}}。 |
max_actions_per_step | int | 10 | 每个步骤里可执行的最大动作数,用于控制 Agent 过度频繁操作。 |
max_failures | int | 3 | 允许 Agent 失败的最大次数,超过则停止任务。 |
retry_delay | int (秒) | 10 | 当遇到限流 (rate limit) 或可重试的错误时,等待多少秒后再次尝试。 |
generate_gif | bool 或 str (路径) | False | 是否录制浏览器过程生成 GIF。为 True 时自动生成随机文件名;为字符串时将 GIF 存储到该路径。 |
1.2. Agent 执行流程图
2. Browser 配置
Browser-use 提供两个主要配置类:
- BrowserConfig:控制浏览器整体行为
- BrowserContextConfig:控制单个上下文(浏览器标签页/会话)的行为

4. Prompt
用于 控制 Agent 的行为与能力,对其整体逻辑有深层影响。
自定义提示会显著影响性能、稳定性和输出风格。
message_context 字段
5. 持久化会话
增加 Cookie
python
context_config = BrowserContextConfig(cookies_file="cookies.json")
五、Demo 示例
1. 简单示例
python
#!/usr/bin/env python3
# -*- coding: utf-8 -*-
import asyncio
from dotenv import load_dotenv
from langchain_openai import ChatOpenAI
from browser_use import Agent
load_dotenv()
llm = ChatOpenAI(model="gpt-4o")
async def main():
agent = Agent(
task="打开 https://cn.vuejs.org/guide/essentials/computed,获取页面里所有的 h2 标签文本及所有的 a 标签文本(以及它的 href)",
llm=llm,
)
result = await agent.run()
print('result:',result)
if __name__ == "__main__":
asyncio.run(main())
1.1. 核心流程:
- 从 .env 中读取 OPENAI_API_KEY 等信息,初始化 ChatOpenAI。
- 创建一个 Agent,指定 task 即描述智能体要完成的任务。
- 调用 agent.run() 发起执行,包括浏览器自动化与 LLM 结合的流程。
2. 使用本地的 Chrome 浏览器
python
#!/usr/bin/env python3
# -*- coding: utf-8 -*-
from browser_use import Agent, Browser, BrowserConfig
from langchain_openai import ChatOpenAI
from dotenv import load_dotenv
import asyncio
load_dotenv()
browser = Browser(
config=BrowserConfig(
chrome_instance_path='/Applications/Google Chrome.app/Contents/MacOS/Google Chrome',
)
)
llm = ChatOpenAI(model="gpt-4o")
agent = Agent(
task="打开 https://cn.vuejs.org/guide/essentials/computed,获取页面里所有的 h2 标签文本及所有的 a 标签文本(以及它的 href)",
llm=llm,
browser=browser,
)
async def main():
await agent.run()
await browser.close()
if __name__ == '__main__':
asyncio.run(main())

你正在访问一个公司内部 Wiki 系统:http://wiki.xxx.com/pages/
你的目标是:
1. 打开该页面并使用搜索功能,输入关键词:RAP
2. 等待页面加载完毕,提取所有与搜索结果相关的条目,包括标题、简要描述和对应链接。
3. 优先提取条目中出现 "接口管理"、"Mock"、"权限" 等关键词的内容。
4. 将所有结果以列表形式返回。
请确保你的返回格式如下:
{
"posts": [
{
"post_title": "xxx",
"post_url": "http://..."
},
...
]
}
"""
controller = Controller(output_model=WikiResults)
async def main():
task = "搜索 Wiki 中有关 RAP 的内容"
model = ChatOpenAI(model='gpt-4o')
agent = Agent(
task=task,
llm=model,
controller=controller,
browser=browser,
message_context=instruction_message
)
history = await agent.run()
result = history.final_result()
if result:
parsed: WikiResults = WikiResults.model_validate_json(result)

print(f'Title: {post.post_title}')
print(f'URL: {post.post_url}')
else:
print('No result')
if __name__ == '__main__':
asyncio.run(main())
4. 多个 Agent 执行
python
agent1 = Agent(
task="打开 https://cn.vuejs.org/guide/essentials/computed,获取页面里所有的 h2 标签文本及所有的 a 标签文本(以及它的 href)",
llm=llm,
use_vision=False
)
result1 = await agent1.run()
agent2 = Agent(
task="打开 https://docs.browser-use.com/customize/custom-functions,获取页面里所有的 h2 标签文本及所有的 a 标签文本(以及它的 href)",
llm=llm,
use_vision=False
)
result2 = await agent2.run()
六、常见操作
1. 修改 LLM 模型
python
llm = ChatOpenAI(model="gpt-3.5-turbo")
或
python
llm = ChatOpenAI(model="gpt-4o")
2. 在 .env 中设置 API Key
plain
OPENAI_API_KEY=sk-xxxx
ANTHROPIC_API_KEY=xxxxxx
如果你还需使用其他模型(如 Cohere、HuggingFace Hub),可一并配置对应的 Key,并在 Python 脚本中初始化相应的 LLM 对象。
3. 官方文档示例
在 docs.browser-use.com/introductio... 可以找到更多场景示例,比如如何定制 browser-use 的 Tools、配合 PythonREPLTool 扩展执行 Python 脚本等。
七、UI 测试方式
1. 安装 Gradio
plain
pip3 install gradio
2. 运行示例
python
import asyncio
import gradio as gr
from dotenv import load_dotenv
from langchain_openai import ChatOpenAI
from browser_use import Agent
load_dotenv()
llm=ChatOpenAI(base_url='https://api.deepseek.com/v1', model='deepseek-chat', api_key="sk-XXX")
async def run_browser_task(
task: str,
) -> str:
try:
print('task', task)
agent = Agent(
task=task,
llm=llm,
use_vision=False
)
result = await agent.run()
print('final_result()', result.final_result())
return result
except Exception as e:
return f'Error: {str(e)}'
def create_ui():
with gr.Blocks(title='Browser Use GUI') as interface:
gr.Markdown('# Browser Use Task Automation')
with gr.Row():
with gr.Column():
task = gr.Textbox(
label='Task Description',
placeholder='Task 描述',
lines=3,
)
model = gr.Dropdown(
choices=['gpt-4', 'gpt-3.5-turbo'], label='Model', value='gpt-4'
)
headless = gr.Checkbox(label='Run Headless', value=True)
submit_btn = gr.Button('Run Task')
with gr.Column():
output = gr.Textbox(label='Output', lines=10, interactive=False)
submit_btn.click(
fn=lambda *args: asyncio.run(run_browser_task(task.value)),
inputs=[task, model, headless],
outputs=output,
)
return interface
if __name__ == '__main__':
demo = create_ui()
demo.launch()
打开终端提示的地址,就能看到一个简易的 web 界面,在界面中输入 task 等信息测试智能体。

八、常见问题 & 解决思路
- 报错:playwright not installed 或 executable path not found
- 请确认已执行 playwright install chromium,且安装成功。
- Python 版本过低
- Browser-use 要求 Python >= 3.11,如果你使用的是 3.10 或更低版本,需要升级环境。
- LLM 调用失败
- 检查是否在 .env 中填写了正确的 API key,或你的 Key 是否仍在有效期内。
- 一直执行 Step1
- Key 没钱了...
- UI Demo 启动后无法访问
- 可能是端口占用,或者 Gradio 版本过旧。尝试更新 gradio 或换一个端口。
- 长时间卡住/超时
- 检查网络环境,LLM 请求或浏览器加载是否耗时过长。
- DeepSeek
- 需要添加 use_vision=False 字段
九、总结
Browser-use 让 AI 与浏览器的结合变得更便捷,能够快速构建出"会浏览网页、抓取信息、进行动态交互"的智能体。只需简单的配置与几行代码,就能让 LLM 自动处理网页操作,为项目带来更多可能性。
- 使用 Python >= 3.11;
- 安装并配置好 Playwright;
- 在主代码中初始化 Agent 并提供 LLM;
- 在 .env 中存放 API Keys;
