  • New : Including selection of Themes for elegant appearance
  • WYSIWYG visual IDE. Raudus uses offscreen WebKit engine to deliver exact appearance of web-controls to IDE. Just place a button on a form and in a second the offscreen WebKit will paint it as it will appear in browser or mobile device.
  • Delphi-style application and forms.
  • Visual and non-visual components, delphi-style event handlers.
  • Coding in Pascal only. Minimal use of HTML, CSS and JavaScript. PHP is not used.
  • Easy debugging. Run application, refresh browser page and debug.
  • Truly stateful server-side applications. Close and open browser - and return to the same state.
  • AJAX techniques. Asynchronous requests. Page never reloads.
  • Timers, publishers (let you deliver pictures, HTML and arbitrary content to page).
  • TDataSource-compatible components to view and edit data.
  • Create your own components using HTML5, CSS3 and JavaScript.
  • High performance. Native server-side code is created.
  • User interface logic is kept securely on server. No code obfuscation needed. You do not risk to disclose your sources.
