Opera’s debugging tool evolves to enhance compatibility

May 4, 2010

Today 100,000 Web developers rely on Opera Dragonfly

Oslo, Norway - May 4, 2010

Opera Dragonfly is actively used by more than 100,000 Web developers each day. This full-featured debugging environment has rapidly grown in usage since the release of Opera 10.50, on March 2, 2010.

Opera has recently changed its license for usage of Opera Dragonfly, from BSD to Apache 2.0. The Apache 2.0 license includes a patent policy promise that allows people to use Opera Dragonfly or Scope regardless of patents held by Opera Software or any other contributor. Opera's Scope protocol is used for communication between the Opera browser and Opera Dragonfly.

"We are putting more focus into Opera's Web developer tools in order to enhance compatibility and platform building activities. As we have stated previously, we will not be satisfied until Opera has the best Web developer tools in the industry," said Christen Krogh, Chief Development Officer, Opera Software. "We encourage more Web developers to join our mission, try out our products and share their feedback, in order to help us continually improve our offerings."
