The debug flag conversion could be more explicit and safer. The current implementation may not handle string values like 'false' or '0' correctly.

debug = os.getenv('DEBUG', 'false').lower() in ('true', '1', 'yes', 'on')

This approach properly converts string environment variables to boolean values, handling common representations of false/true.

Consider adding error handling for the port conversion and app startup. The current code could fail silently or with unclear errors.

try:
    port_num = int(port)
    print(f'Loading backend version {__version__} on port {port_num}')
    app.run(host='0.0.0.0', port=port_num, debug=debug)
except ValueError:
    print(f'Error: Invalid port number "{port}"')
    sys.exit(1)
except Exception as e:
    print(f'Error starting server: {e}')
    sys.exit(1)

This provides better error handling and user feedback when the application fails to start.
