Note: This library is currently in active development, and its API may undergo changes without notice at any time.
Note: This project originally started as a working proof of concept and does not aim to offer extensive support or
documentation. It serves as a fundamental demonstration of the concept and should be considered a foundation for further
development or experimentation.
This library enables you to work with BAS (BrowserAutomationStudio) using headless Chromium browsers and a
customizable Windows GUI program, while controlling it with Python ❤️.
- BrowserAutomationStudio Integration: Run BAS seamlessly with headless browsers while enjoying the convenience of a user-friendly and customizable Windows GUI program through BrowserAutomationStudio.
- Unique Fingerprint Feature: The application includes a unique feature that assigns a
fingerprintto each browser instance using FingerprintSwitcher. Please be aware that this is paid service. - Proxy Support: The application supports proxy providers such as Brightdata. Please note that this is a paid service.
- Executing Browser Automation Studio (BAS) Actions from Python: Implement BAS actions from Python using the
un-documented API. This includes actions such as retrieving page source,
emulating mouse movements, etc. (Note: Not all functions are currently supported). - Playwright Control: The application leverages Playwright to efficiently manage and control BAS.
The functioning of BAS (Browser Automation Studio) involves the following steps:
- Initial Execution: Upon initiation, BAS runs cmd_initial.py. This script is responsible for creating tasks and storing them on the disk for later use.
- Data Acquisition and Browser Configuration: BAS then retrieves the necessary data, configures, and launches browser instances based on the tasks provided earlier.
- Task Execution: Following the browser setup, BAS executes cmd_worker.py using the
task_idandremote-debugging-portnumber as command-line parameters. - Task Handling: cmd_worker.py obtains both the
ws_endpointandremote-debugging-portfrom the command line. It then manages complex tasks using Playwright. These tasks can range from opening a webpage to filling out forms or even taking screenshots. - Task Completion: Once the tasks have been completed, BAS terminates the browser instances and exits.
The result of running cmd_worker.py is as follows:
{
"tasks_file": "C:\\Users\\Administrator\\AppData\\Local\\PyBASProfilesTasks\\tasks.json"

For the optimal running of this application, the following system requirements are necessary:
- Operating System: The application is compatible with Windows 10/11 and Windows Server 2022 (tested on 21H2).
- Python: Ensure you have Python 3.11 or higher installed. If not, you can download it from the official Python website.
- Poetry: This is a necessary tool for managing Python dependencies. You can find the installation guide on the official Poetry documentation.
- Git: The application requires Git for version control. If it's not already installed on your system, you can download it from the official Git website.
- Make: This is an optional tool, it can be downloaded from the Chocolatey website.
- FingerprintSwitcher License: Please note that this is a paid feature. You will need a valid license for FingerprintSwitcher to access its functionalities.
To work with the most recent development version of pybas-automation, follow the steps outlined below:
- Clone the Repository: Clone the
py-bas-automationrepository from GitHub. - Navigate to the Directory: Once cloned, navigate to the
py-bas-automationdirectory on your local system. - Install Dependencies: With Poetry, install all the necessary dependencies.
Here are the corresponding commands for each step:
git clone git@github.com:sergerdn/py-bas-automation.git
cd py-bas-automation
git lfs pull
poetry installIf you wish to incorporate pybas-automation into your project, execute the following command:
poetry add pybas-automationPlease note that this is not currently recommended as the latest release may have unresolved issues.
-
Download the BAS Program: Begin by downloading the latest version of the compiled BAS program, called
PyBasFree.zip. You can find this file in the project directory under PyBasFree.zip. After downloading, extract the contents and executePyBasFree.exe. -
Set Variables in the BAS GUI: After running the BAS program, proceed to set the necessary variables within the BAS graphical user interface (GUI).
-
Set Up Proxy Provider: If you are using a proxy provider, you will need to configure it within the BAS GUI. This can be accomplished by navigating to the
Proxy Settingsoption in the vertical menu and selecting the appropriate provider.
-
Start the Program: Once all variables have been set, click the "OK" button to initiate the program.
This guide introduces a Python script that integrates the Browser Automation Studio (BAS) with py-bas-automation.
The
purpose is to handle the creation of browser profiles through FingerprintSwitcher and manage tasks related to these
profiles.
This script facilitates the integration between BAS (Browser Automation Studio) and py-bas-automation. It manages
the creation of browser profiles using FingerprintSwitcher and generates tasks associated with these profiles.
- Initialization: Import essential modules and configure logging.
- Browser Profiles: Utilize
FingerprintSwitcher's fingerprint key to generate or manage browser profiles. - Proxy Support: Configure proxy settings for each browser profile in full-automatic mode by handling proxy
providers. Note: at the moment only
Brightdatais supported. - Tasks Generation: Generate an associated task for each browser profile and store it.

main()This script demonstrates how to execute tasks using the Playwright Python library in conjunction with the
pybas_automation package. The primary goal is to fetch task data, connect to an existing browser instance using
Playwright, and perform actions on a webpage.
- Initialization: Import necessary libraries and set up our task id and debugging port.
- Task Storage: Fetch a specific task from our task storage.
- Remote Browser Connection: Use the remote debugging port to get a WebSocket endpoint, which allows us to connect to an existing browser instance.
- Executing Browser Automation Studio (BAS) Actions from Python: Implement BAS actions from Python using the un-documented API. This includes actions such as retrieving page source, emulating mouse movements, etc. (Note: Not all functions are currently supported).
