Core Benefits

• 🙊 Language Choice
  Web4 ends JavaScript’s monopoly on building dynamic user interfaces on the web.
• 👯‍♀️ Multiplayer Reactivity
  When application state lives on the server, multiple connected clients can react to the same state change.
• 🙈 Offline Reactivity
  Bidirectional protocols enable local-first synchronizations and apps continue to function even without a network connection.
• 🪶 Zero-Cost Dependencies
  When applications execute remotely, binaries can grow to gigabytes in size without impacting user experience because they are never transferred to the browser.

Note

XTML (eXtramural Templating Markup Language) is intended to be a hopeful W3C candidate recommendation for HTML6
