Configuration

SWEer can be configured using environment variables:

Browser Configuration

You can configure which browser backend to use:

# Use Firefox instead of the default Chromium
export SWEER_BROWSER_TYPE="firefox"
sweer-backend

# Use Chromium (default)
export SWEER_BROWSER_TYPE="chromium"
sweer-backend

Supported browser types:

• chromium (default) - Uses Chromium browser
• firefox - Uses Firefox browser

Custom Browser Executable Paths

You can specify custom installations of browsers instead of using Playwright's default bundled browsers:

# Use a custom Chromium installation
export SWEER_CHROMIUM_EXECUTABLE_PATH="/usr/bin/chromium-browser"
export SWEER_BROWSER_TYPE="chromium"
sweer-backend

# Use a custom Firefox installation
export SWEER_FIREFOX_EXECUTABLE_PATH="/usr/bin/firefox"
export SWEER_BROWSER_TYPE="firefox"
sweer-backend

This is useful when:

• You want to use a system-installed browser instead of Playwright's bundled version
• You need to use a specific browser version
• You want to use a browser with custom configurations or extensions pre-installed
• You're working in an environment where Playwright's bundled browsers aren't available

Other Configuration Options

# Enable automatic screenshotting after each action
export SWEER_AUTOSCREENSHOT="1"

# Configure window size
export SWEER_WINDOW_WIDTH="1280"
export SWEER_WINDOW_HEIGHT="720"

# Run browser in headed mode (visible window)
export SWEER_HEADLESS="0"

# Change screenshot delay (in seconds)
export SWEER_SCREENSHOT_DELAY="0.5"

If navigating a lot, you can activate automatic screenshotting with

export SWEER_AUTOSCREENSHOT="1"
