Browser Use

Procedures and concepts for the Browser Use integration.

The following documentation is for Browser Use v1.14.4 (BDK).

Overview

The Browser Use book enables you to perform web automation using natural language. Use plain English to describe a task, and a remote browser agent will execute it.

The browser agent can perform a range of web automation tasks, including navigating pages, filling out forms, and extracting structured data, all with full traceability. Every action is logged with detailed step plans and unique session IDs. Take a look at this quick example:

Prerequisites

1. Required Books

The following Book(s) need to be added to your agent so it can learn and understand the automation procedures defined within them:

• Browser Use

How to Add the Book(s)

1. Go to Books → All Books.

2. Search for the name of the book and click on it.

3. Click on Install or Add Connection to add the book to your agent.

4. If adding a connection, you'll be prompted for connectivity details.

Concept	Description	Type	Required	Default Value
browser	The reference to the provisioned browser instance.	browser instance	Yes	(no default)
task	An object containing task configuration (created with the Browser Automation widget).	browser task	Yes	(no default)

Output Concepts

Concept	Description	Type
visual log	A series of screenshots showing each step the browser took.	file
detailed plan	A text summary of the steps taken to automate the task.	text
result	The data extracted or produced by the agent upon completing the task.	any
browser run id	The identifier of the browser run.	text
browser files	A list of files generated by the agent upon completing the task.	file

Examples

Get the Weather in Philadelphia. Task instructions: "Search for the 'current weather in Philadelphia' and extract the temperature"

provision a browser

Output Concepts

Concept	Description	Type
answer	None	browser instance

Examples

Provision an AWS browser and get the reference to the browser instance:

to run a playwright script on a browser and get the result, the browser run id and the browser files

Execute a custom Playwright script on the provisioned browser.

Note: Before using this procedure, you must first "provision a browser". The script must: 1. Be stored in S3 2. Contain an async function: run(page, context, browser, params, llm=None) 3. Be accessible from the browser farm's AWS credentials

Input Concepts

Concept	Description	Type	Required	Default Value
browser	Reference to the provisioned browser instance.	browser instance	Yes	(no default)
playwright script	S3 URI of the Playwright script (e.g., "s3://bucket/scripts/my_script.py").	text	Yes	(no default)
parameter json	Optional dictionary of parameters to pass to the script.	json	No	(no default)

Output Concepts

Concept	Description	Type
result	Data returned by the script execution.	any
browser run id	Identifier of the browser run.	text
browser files	Files generated during script execution.	file

Examples

Run a custom data extraction script with parameters:

provision a browser
the script s3 uri is "s3://my-bucket/scripts/123456789/weather_search.py"
run the script s3 uri on the browser with parameters {"location": "San Francisco, CA"} and get the result, the browser run id and the browser files
