  • Group video calls and screen sharing require the Pro plan; Starter is limited to 1-1 video calls
  • Group video calls are capped at 20 participants even on Enterprise
  • Single Sign-On and Active Directory sync are Enterprise only
  • Enterprise is quote only, with no published rate, and is positioned for organisations with 100 or more members
  • Unlimited auto-join and announcement channels require Enterprise; Starter and Pro get one of each

Lucidchart

  • Interface can overwhelm new users due to extensive features and customization options
  • Drag-and-drop canvas can feel clunky compared to modern whiteboard tools like Miro
