Possible disadvantages

    Compared to desktop Markdown editors, Markdown-Viewer.com has a more limited set of features, which might not meet the needs of advanced users who require additional editing tools and functionalities.
  • Internet Dependency
    As an online tool, it requires a stable internet connection to function, which might not be ideal for users with limited or unreliable internet access.
  • Privacy Concerns
    Uploading files to a web-based service could raise privacy concerns as sensitive data could potentially be accessed or logged by third parties.

    Obsidian uses Markdown, making it easy to format text and compatible with many other text editors and tools.

Possible disadvantages

    Obsidian can be complex and overwhelming for beginners due to its extensive features and customizable nature.

    While local-first is great for privacy, it requires additional steps or third-party solutions for syncing across devices.

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