Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

CodeSandbox

  • Detailed paid plan pricing was not published on the accessible pages, making cost comparison difficult.
  • Focus has shifted toward programmatic sandbox infrastructure, which may be less approachable for casual users just wanting a quick online editor.
  • Public sandboxes are visible to others by default, which is not ideal for proprietary code.

Excalidraw

  • Advanced features (unlimited private scenes/folders, cloud storage, access management, presentations, extended AI, team management) are gated behind Excalidraw+
  • Free hosted version persists via scene links/local storage rather than a managed multi-scene workspace
  • Self-hosting the full collaborative stack requires standing up a websocket server and storage beyond the npm editor package
  • No official native desktop or app-store mobile apps - web/PWA only
