Possible disadvantages

• Basic Design
  The user interface, while functional, is quite basic and may not appeal to users who prefer more visually engaging and modern designs.
• Maintenance and Support
  As an open-source project, it may not provide the same level of dedicated support and regular updates as commercial alternatives, potentially leading to issues with maintenance.
