Skyfire Web Browser is a mobile web browser which renders requested web page on a proprietary server and relays it to the browser on the end user's mobile phone which displays the content. Skyfire currently runs on Android and iOS.^[1] As of 31 December 2010, it no longer supports Symbian OS or Windows Mobile.^[2] Skyfire comprises two distinct generations of mobile browser technology. In Skyfire's first generation (1.x) browser, a web page is fully rendered by a server separate from the mobile device, similar to the operation of a thin client.^[3] This approach is also used by Opera Mini. Skyfire's second generation (2.x) browser employs a hybrid approach, using a conventional rendering of Web pages on the handheld device, but streaming video from Skyfire's servers.^[4] Skyfire Web Browser is one of three main products for telecommunications offered by the company Skyfire.

Skyfire Company

Skyfire is a cloud solutions for mobility company founded in 2007. They offer network optimization technologies including video optimization and monetization tools for carriers. Skyfire maintains their Skyfire Web Browser, one of the top web browsers for the Android and Apple iOS (for both the iPhone and iPad) platforms, as a showcase and laboratory for its technology. Skyfire was recognized as no. 4 on Light Reading’s 2011 Startups to Watch list and a winner of the 2012 Red Herring Awards award in recognition of the leading private companies from Americas. Skyfire is funded by Lightspeed Venture Partners, Matrix Partners, Trinity Ventures, and Verizon Ventures.

Features

Skyfire is a web browser which operates by rendering requested web page on a proprietary server.

Rendered output is relayed to the browser (running on the end user's mobile phone), which displays the content.

Skyfire 1.x

In Skyfire's first-generation browser, all content is rendered at Skyfire's servers using the Gecko rendering engine^[5] before sending the rendered output to the browser. The output is sent as images annotated with interactive items such as links and text-fields.

Consequently, the browser is able to use features from a full desktop web browser without the need to have a powerful mobile device. Features such as Adobe Flash, Silverlight, and QuickTime are usable without additional plug-ins on the device, and can be easily updated server-side without the need to update millions of individual client installations.^[6]

Downsides include that the user experience can be adversely affected by the abilities of the Skyfire server. For example, a user with an excellent 3.5G or Wi-Fi connection may still experience slow page loading and unwatchable video. Until December 2009, Skyfire's servers demonstrated few symptoms of limits. Since then, the browser's performance has degraded significantly for users of Skyfire 1.5.^[7][8][9]

Skyfire 2.x

Skyfire's second generation browser uses the same three-tiered technology, but only for content that cannot be effectively processed at the handheld. Web page text and images, for example, are rendered on the phone. Flash video, on the other hand, is rendered at Skyfire's servers, re-encoded to a device-compatible video format, then relayed to the phone.

Flash video is currently supported with plans to add support for Windows Media, Silverlight, QuickTime, and others.^[10]

Skyfire 2.x builds on the open source WebKit layout engine.

Skyfire 3.x

includes more available website support for video

Performance and other issues

Although the recently-added Android version of Skyfire has been updated to 2.0, Symbian and Windows Mobile are limited to version 1.5. Skyfire 1.5 users have, for more than six months, registered complaints regarding slow page loading and the inability to view web videos without severe frame rate and audio glitches. Though since skyfire has implemented restrictions to prevent use from most unsupported countries, page loading and viewing web videos has improved. Other complaints center on a text-rendering feature that enlarges some text several times its normal size. The original intent was to remove the need for the user to "zoom in" to the text of articles. However, the fragmented and seemingly random nature of the feature requires repeated zooming in to read captions, view pictures, find links and navigate a given website, then zooming out to read an article. The large, pixellated characters thus make even casual browsing (according to one editor's opinion) an awkward proposition. Unlike in prior versions of Skyfire, the text-rendering feature is locked in with no option to turn it off.^{[14][15][16][17][18]}

A new concern has cropped up as of early June: in conjunction with virtually unplayable video, standard web pages can take between two and three minutes to load.^[19]

Skyfire's privacy policy states that "no data is ever transmitted to our servers when users access secure (HTTPS) sites".^[20] If Skyfire were to transcode HTTPS sites, that would create a potential security risk.^[21]

Windows Mobile support (aka WMS)

In November 2010, Windows Mobile users began reporting that Skyfire would immediately close upon opening, stating "Sorry: Due to strong demand we cannot provide service at this time. Please try again later."^[22] Several days later, the Skyfire developers announced that they would be ending support for Symbian and Windows Mobile,^[23] and possibly releasing Skyfire 2.x for the Windows Phone 7 and MeeGo platforms at a later date.

Awards and recognition

Skyfire's Web Browser has won numerous awards over the years. In 2008, it was voted one of the six must have applications for Windows Mobile by Read Write Web^[24] and also received the Mobile Maverick Award from Laptop Magazine.^[25] It received the Webby People's Voice Award for Best Mobile Application in 2009 ^[26] and was also recognized in 2010 by PC World as the World's Best Third-Party Android Browser.^[27]
