UPDATE: The blink based Opera uses the same developer tools as Chrome, the following applies to the Presto-based Opera <=V12

Opera DragonFly is a fully featured development tool:

  • Edit and modify the DOM tree and any CSS live. Click on elements to find them in the DOM.
  • Full breakpoint-and-step javascript debugger, including a remote debugger protocol for development on any device.
  • Network requests, HTTP headers and more. AJAX friendly.
  • Very helpful error messages, better tracing than some other tools.
  • You can update to the cutting edge branch to get the latest features. Simply, go to opera:config#DeveloperTools|DeveloperToolsURL and use https://dragonfly.opera.com/app/cutting-edge.

See more information on the developer blog, or read more tutorials on its usage at dev.opera.com...


Try Firebug Lite.

    Upgrade to Opera 9 or 10 - the internal tool gets a lot better. It's called Dragonfly by the way. – Ant Sep 29 '09 at 12:52
  • Dragonfly's still in Alpha but very promising – MartW Sep 29 '09 at 13:09
