brui-core 1.2.0

Core browser UI automation framework

BRUI Core (Browser UI Automation Core)

A flexible and robust browser UI automation framework that provides essential functionality for browser-based UI automation projects.

Features

• Browser Management: Automated browser launching and control across different operating systems
• Configuration Handling: Flexible configuration management with TOML and environment variable support
• Clipboard Integration: Easy clipboard monitoring and manipulation
• UI Integration Base: Extensible base classes for UI automation
• Cross-Platform Support: Works on Linux and macOS

Installation

From PyPI (recommended)

pip install brui_core

From source (editable)

Using uv (recommended)

git clone https://github.com/AutoByteus/brui_core.git
cd brui_core
uv sync

Development / testing extras

With uv, dev dependencies are synced by default. To sync all extras:

uv sync --all-extras

Build the distribution

This project utilizes uv for modern, isolated builds:

# Build with specific Python version
uv build --python 3.11

This will produce the source distribution and wheel in the dist/ directory.

Quick Start

from brui_core.ui_integrator import UIIntegrator

async def main():
    # Initialize the UI integrator
    ui = UIIntegrator()
    await ui.initialize()

    try:
        # Your automation code here
        pass
    finally:
        # Clean up
        await ui.close()

# Run with asyncio
import asyncio
asyncio.run(main())

Requirements

• Python 3.8+
• Playwright (pinned in pyproject.toml and installed automatically)
• Chrome/Chromium browser installed
• Pillow, pyperclip, and other transitive dependencies installed with the package

Configuration

The framework is configured using environment variables:

Environment Variable	Description	Default
CHROME_PROFILE_DIRECTORY	Chrome profile to use	Profile 1
CHROME_REMOTE_DEBUGGING_PORT	Remote debugging port	9222
CHROME_DOWNLOAD_DIRECTORY	Directory for downloads	(System Default)
CHROME_USER_DATA_DIR	User data directory for session persistence	(System Default)

Session Persistence (Logins & Cookies)

To maintain login states (cookies, local storage, cache) across different automation runs, you can configure the user_data_dir.

• Default Behavior: If user_data_dir is not set, Chrome uses your system's default user profile (e.g., ~/.config/google-chrome on Linux). This means your automation shares the same session as your personal browsing.
• Custom / Isolated Session: To keep your automation isolated (or to maintain multiple distinct signed-in states), set user_data_dir to a specific path. As long as you point to the same directory, Chrome will restore your previous session, keeping you logged in.
• Chrome/Chromium 136+ Requirement: Recent Chrome and Chromium versions (136+) refuse to enable remote debugging on the default profile directory. You must set user_data_dir to a non-default path for CDP to work.

Example (Environment Variable):

export CHROME_USER_DATA_DIR="./my-bot-profile"
