Shiira is a web browser written in Cocoa. It uses the KHTML rendering engine provided by Apple’s Web Kit. Since this is the same rendering engine used by Safari, HTML content rendered by Shiira will look the same as in Apple’s own browser.

The browser is being developed by a group in Japan, and they are also creating English versions of the browser. Today, they released version 1.0 for OS X 10.4. This version only works with Tiger. To try it out on Panther, you will need to download 0.9.4.

I checked this browser out a while back when it was around version 0.5 and I was impressed with where it was heading.

One of the nicer things they have incorporated into the 1.0 release is Tab Expose, which allows you to see all the pages you have open in tabs the same way you view the different applications in Expose.

If you are looking for an alternative to Safari and are not interested in Firefox, give this one a shot.
