DESCRIPTION
Stainless is a multi-process browser for OS X Leopard and Snow Leopard.

Although Stainless started out as a technology demo to showcase our own multi-processing architecture in response to Google Chrome, we've been inspired by our growing fanbase to forge ahead and craft Stainless into a full-fledged browser. In fact, Stainless now has features you won't find in Chrome or in any other browser.

A prime example is parallel sessions, which allow you to log into a site using different credentials in separate tabs at the same time. This new technology is woven throughout Stainless, from the private cookie storage system, to session-aware bookmarks that remember the session in which they were saved. We're excited to showcase what we believe is a true browser innovation.

WHAT'S NEW
Version 0.7.5:
  • added: url and search autocompletion
  • added: new theme-capable UI (API available in future version)
  • added: new tab and security preferences
  • fixed: nested group contextual menus don't work
  • fixed: create groups from open tabs fails when no tabs are open
  • fixed: switching to empty tab group doesn't update bookmarks
REQUIREMENTS
Mac OS X 10.5 or later.

TOMIS  At first run it quite clearly states that this should be considered a "tech demo" to prove that running each tab in a separate process is doable and usable on the Mac. Hopefully the WebKit/Safari team will pick up on this idea.

Props for the effort, it's certainly interesting work. People marking it down seam to be missing the point.

TUISHIMI  Understanding this is a TECHNOLOGY PREVIEW I found it to be very interesting. While you claim your solution to having each tab be a separate process is likely not as complex an implementation as Google's, it is great that you could toss something like this together in short order.

Works as advertised. Won't woo me from OmniWeb just yet, but it has potential. ;)

I am giving a high rating because this is NOT just another webkit test program tossed together in 15 minutes - and because it does what you claim it will do, nothing more, nothing less.

FRANCOLA  Great to see someone working on this! Please keep it up. I love using Chrome during the day at work. Please don't be discouraged by the naive opinions of those who do not understand the importance of growth and change.

Oh, and could you please make the next build so that the window will appear (after being closed) by just clicking the dock icon and not having to select New Window from the menu or shortcut. Maybe some history, bookmarks, extensions... Just kidding. ;) Keep up the good work!

Thanks!

DR. GIRLFRIEND  This browser sounds really exciting! I'm a long time Firefox user (since the days when it was called Phoenix) and I'm truly disappointed in how bloated, buggy, and memory-intensive Firefox has become. It all boils down to leadership and the Mozilla Foundation has been operating like a beast with too many heads for years now. I want my lean, mean privacy-conscious browser back -- not this gargantuan, crash-prone imposter who shares a bed with Google.

As soon as this browser implements 1Password and a decent ad-blocking program, Firefox's days are numbered.

DOUG S.  Lately I've been considering switching my browser. I am a web designer so I use all the big players on a regular basis and they each have their issues. Mostly it comes down to their inability to have a large number of tabs open without experiencing excessive amounts of lag. I find this to be unacceptable.

Since I use every major browser regularly I know all their shortcomings and know none of them meet my requirements. Though Stainless is not complete it shows the most promise out of all of them. It's more than a proof of concept, like CrossOver Chromium, it's an actual working browser and it works pretty well.

However, it's missing history and bookmark support. Also I'd love to see some 1Password support just as much, though this could be achieved by implementing a plugin architecture similar to Safari's. There are other features that I would love to see added that you don't really find in any other browser without plugins such as bookmarks powered by tags and smart-folders.

OK, so it's not complete and still has lots of room to grow. That being said I can't think of a single other browser that I'm really looking forward to the next version of like I am for Stainless. I hope this browser moves out of the beta phase and into real development. I know I'd use it as my default browser if it did.

GREGMLR  Stainless could be a great browser but at current there are quite a few bugs still present in the program. I downloaded Stainless to use for just browsing MySpace, however whenever I'm logged into MySpace, opening a link in a new tab will log me out in the new tab but I can go back to the old one and I'm still logged in. So even though there are tabs, I'm pretty much confined to using just the one. Another fluke in the program would be that after closing a window, but leaving Stainless open in the dock, in order to open a new window you can't simply click the dock icon like with Safari. You have to click the dock icon, then go to the menu bar and click "File, New Window." This will also result in logging you out of MySpace (unlike with Safari) but not other websites (I tried it with BetaNews) so maybe it's just a problem with certain websites.

Other than these problems I'm having, Stainless has great potential to be an awesome browser. The GUI is gorgeous, the best looking browser out there, rivaling even Safari. Plus it's quite snappy and doesn't take up much space which is always a plus.

TUISHIMI  Can't wait to see what the novel ideas are for bookmarking and history. (I am being serious)!

E_COMMERCE  Fascinating browser to use, and a taste of what Chrome may one day be like on the Mac. A couple of minor things I noticed (beyond the obvious, proof-of-concept issues):

- When switching tabs, the window noticeably deactivates and reactivates.

- There doesn't appear to be a parent process that owns all of the tabs as in Google Chrome.

- With search integrated into the URL bar, typing "foo" for "http://www.foo.com" does not work.

I'll be watching this one closely. :)

STANISHJOHND  Wonder why this app can't be built to work in Tiger, too. Before people say upgrade to Leopard, I can't because I have an older mac that isn't upgradeable to this latest version.

JOHNDSTANISH  Found out why one couldn't make this work on 10.4. Apple never documented the API's for process management with Tiger. With 10.5, the API's are documented and is the reason you can install procfs with MacFuse.
