Sleipnir is a modern web browser created by the Japanese company Fenrir, distinguished by a huge number of available features, as well as support for CSS3 and HTML 5. One of the most important elements of the program is the Fenrir Pass service, which enables full synchronization of the most important data from Sleipnir browser, between desktop computers and mobile devices. Thanks to this, we can browse the web pages on the computer's desktop, and after a while open them automatically on a mobile device.

That's not all. For example, if you dial any phone number from the website directly from your computer, it will automatically be sent to your smartphone. Sleipnir supports two web rendering engines - Trident and Blink (Blink is enabled by default).

Supports add-ons and extensions that are compatible with Google Chrome and offers the ability to translate various texts and documents. The program also has an advanced RSS feed reader - FeedReader, which, unlike other readers, stores the obtained data in the local environment. This way you can view and read the latest news much faster and more securely.

In addition, it supports data filtering and importing from Google Reader. Sleipnir uses keyboard shortcuts and mouse gestures. It is designed so that it should not cause problems when browsing the web pages in full screen mode.

In addition, it offers convenient management and grouping of tabs, as well as the creation of screenshots from the currently open website.
