User agent string/ID

The user agent string for Chromium-based versions of Opera resembles the Chrome string with an additional browser signature:

OPR/[version major].[version minor].[build].[patch] (edition)

This signifies the name of the browser (OPR) followed by a series of numbers denoting the build.

An edition may be included in the string, if the build is from the developer or beta pre-release streams, or if the build has been custom-made for an Opera partner. For example, a developer channel release of Opera’s partner build with Yandex may have a signature that looks like:

OPR/25.0.1614.18 (Edition developer-Yx)

The full user agent string looks similar to this:

Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.87 Safari/537.36 OPR/37.0.2178.31 (Edition beta)

This string will vary depending on your operating system and the build number you are using. Broken down, these objects mean:

Mozilla/[version]: Signifies the browser is Mozilla compatible.
(Operating system): Signifies which platform and version of operating system the browser is running on.
AppleWebKit/[build]: Signifies the browser is WebKit compatible.
(Layout engine): Signifies the layout engine used for rendering. KHTML is open-source and developed by the KDE project.
Chrome/[version, build, and patch]: Signifies the browser is Chrome compatible.
Safari/[build]: Signifies that the browser is Safari compatible.
OPR/[version, build, and patch]: Signifies the Opera browser signature (See above).
(Edition): Signifies the edition of the Opera browser.
