  • marked:

    marked is designed to be minimal and does not offer extensive customization options. It focuses on speed and simplicity, which may limit its extensibility compared to other libraries.

  • remark:

    remark is built around a plugin system that enables developers to create custom transformations and linting rules. This modular approach allows for extensive customization and integration of various Markdown processing tasks.
