Opera Dragonfly is a web development tool integrated into the Opera web browser from Opera 9.5 to 12.18, similar to Firebug and development tools built into Mozilla Firefox and Google Chrome.
Supports JavaScript debugging, viewing DOMs, monitoring network traffic, previewing resources, editing colors, etc. It also supports remote debugging, which allows using the Dragonfly feature to be used when debugging a phone, TV, or other desktop computer.
Opera Dragonfly must be downloaded on first use, and function offline afterwards. Opera Dragonfly automatically updates to the latest available version, when connected to the Internet.
Opera Dragonfly is compatible with Presto 2.1 and later, especially Opera Mobile 9.5 and above, Opera Desktop 9.5 and above, and Nintendo DS & amp; Nintendo DSi Browser. The Scope transport protocol (STP) is used for communication between the Opera browser and Opera Dragonfly.

History
Opera Dragonfly development started in May 2008. When Opera Dragonfly development started using BSD license, but later changed to Apache License 2.0.
On September 21, 2011, Opera Dragonfly team announced that since then the release will be more focused on improving on individual components, eg. DOM inspector or UI framework. As soon as a feature for a particular component is implemented, it will be placed in the test path for some initial testing. As part of a new release strategy, they switch Opera Dragonfly to the new version scheme: & lt; major-version & gt ;. & Lt; year & gt ;. & Lt; month & gt ;. & Lt; date & gt ;. & Lt; today-build & gt;
Opera Dragonfly's opt-out ends after Opera 12.x, when Opera switches from Presto's layout engine to Blink and Chromium base. The next version includes Chromium DevTools instead. By 2015, Dragonfly has not been reintroduced, though by 2013, indications are given that it may be at some point back.
