Opera browser is available on many platforms, in different forms, with different modes, engines and levels of standards support. You can easily get confused in such a variety - did you know, for example, that Opera Mini for iOS has three modes, one of which is UIWebViewwith Opera Turbo?

Notes

1. Opera Turbo mode compresses traffic up to 80%, Opera Mini mode - up to 90%.
2. For Opera Turbo, marked with an asterisk, there is also a Video Boost option for video compression.
3. If you determine the position of users based on IP address, be sure to check the header X-Forwarded-For. Thus, you can correctly determine where the user opened your site from in a browser that uses Opera Mini and Opera Turbo proxies.
4. Standards support in Opera Mini is "limited", which means that complex JavaScript, CSS and other dynamic elements may not work as you expect, due to the peculiarities of server rendering and limited device capabilities.
5. Old Opera browsers on the Presto engine, for example, Opera 12 for computers, Opera Mobile Classic, etc. are no longer supported and are not listed in this list.
