Mesa Dynamics has released a technology preview of Stainless, which
the company says is the first multi-process web browser for OS X,
inspired by Google Chrome. Each tab in Stainless runs in a separate
process.
Like Chrome, Stainless also has tabs that can be dragged between
windows, a unified address and search bar, and a private browsing
mode. Stainless is freeware and requires Mac OS X 10.5 (“Leopard”).
Version 0.1 is available immediately for download at
