Possible disadvantages

  • Learning Curve
    Obsidian can be complex and overwhelming for beginners due to its extensive features and customizable nature.
  • Sync Limitations
    While local-first is great for privacy, it requires additional steps or third-party solutions for syncing across devices.
  • No True Real-time Collaboration
    Obsidian lacks native real-time collaboration features, making it less suitable for collaborative work compared to cloud-based solutions.
  • Limited Mobile Features
    The mobile version of Obsidian, while functional, is not as robust as the desktop application, potentially hindering productivity on the go.
  • Dependence on Plugins
    Many advanced features require the use of third-party plugins, which could lead to compatibility issues and reliance on community support.

    Performance might degrade with a very large number of notes or complex graphs, impacting usability.

Possible disadvantages

    As FastNote is a web-based application, users must have an internet connection to access their notes, which could be a limitation in areas with poor connectivity.
  • Security Concerns
