Hey, old friend. OmniWeb first shipped way back in 1995 and was one of the first old-line Mac browsers to make the transition to WebKit in 2003. Believe it or not, OmniGroup recently updated this “lost” labor of love to be Lion compatible.

That happened back in December 2011 (release notes). Yes, it took me a couple extra months to make the discovery, but in doing so I also learned that OmniWeb uses a fairly recent version of WebKit — the same found in Safari 5.0.5.

And, that delivers a respectable 265 points on the HTML5 Test.

Don’t expect Lion fullscreen mode or any other modern OS X features and functionality — OmniWeb v5.0 shipped in 2004. However, its approach to tabbed browsing is kind of neat.

Yes, you can run OmniWeb 5.11.1 (download) on even the newest Macs, but it’s best suited for older Intel and legacy PowerPC Macs, including those running OS X 10.4.8 (Tiger).
