💡 Pro Tips

Use headless=False for debugging

See what the browser is doing while developing your agent

Add waits strategically

wait_for_load_state('networkidle') ensures page is fully loaded

Save cookies for authenticated sessions

Avoid repeated logins by saving and reusing cookies

Use page.pause() for interactive debugging

Pause execution to inspect the page in the browser

Handle errors gracefully

Wrap in try/except and log errors for robust agents

Respect robots.txt and rate limits

Be a good citizen - don't overwhelm target servers

Inspired by Notte — browser agent deployment platform.
