  • File Size
    Paper.js can be relatively large in terms of file size compared to some lightweight alternatives, which might affect load times.
  • Limited to Canvas
    Paper.js is limited to the HTML5 Canvas element, so it doesn't natively support other rendering contexts like SVG.

    While it offers built-in animation support, the flexibility and feature set might not be as extensive as dedicated animation libraries.
  • Learning Curve for Complex Features
    Although it's beginner-friendly for simple tasks, mastering more complex aspects of Paper.js can have a steeper learning curve.
