At Google, we have a saying: “launch early and iterate.” While this approach is usually limited to our engineers, it apparently applies to our mailroom as well! As you may have read in the blogosphere, we hit "send" a bit early on a comic book introducing our new open source browser, Google Chrome. We will be launching the beta version of Google Chrome tomorrow in more than 100 countries.

So why are we launching Google Chrome? Because we believe we can add value for users and, at the same time, help drive innovation on the web.

All of us at Google spend much of our time working inside a browser. We search, chat, email and collaborate in a browser. And in our spare time, we shop, bank, read news and keep in touch with friends -- all using a browser. Because we spend so much time online, we began seriously thinking about what kind of browser could exist if we started from scratch and built on the best elements out there. We realized that the web had evolved from mainly simple text pages to rich, interactive applications and that we needed to completely rethink the browser. What we really needed was not just a browser, but also a modern platform for web pages and applications, and that's what we set out to build.

On the surface, we designed a browser window that is streamlined and simple. To most people, it isn't the browser that matters. It's only a tool to run the important stuff -- the pages, sites and applications that make up the web. Like the classic Google homepage, Google Chrome is clean and fast. It gets out of your way and gets you where you want to go.

Under the hood, we were able to build the foundation of a browser that runs today's complex web applications much better. By keeping each tab in an isolated "sandbox", we were able to prevent one tab from crashing another and provide improved protection from rogue sites. We improved speed and responsiveness across the board. We also built a more powerful JavaScript engine, V8, to power the next generation of web applications that aren't even possible in today's browsers.

This is just the beginning -- Google Chrome is far from done. We're releasing this beta for Windows to start the broader discussion and hear from you as quickly as possible. We're hard at work building versions for Mac and Linux too, and will continue to make it even faster and more robust.

We owe a great debt to many open source projects, and we're committed to continuing on their path. We've used components from Apple's WebKit and Mozilla's Firefox, among others -- and in that spirit, we are making all of our code open source as well. We hope to collaborate with the entire community to help drive the web forward.

The web gets better with more options and innovation. Google Chrome is another option, and we hope it contributes to making the web even better.

So check in again tomorrow to try Google Chrome for yourself. We'll post an update here as soon as it's ready.

<strong>Google Chrome is Google’s open source browser project.</strong> As <a href="http://thetruthaboutmozilla.wordpress.com/2008/02/25/the-google-browser/">rumored before</a> under the name of “Google Browser”, this will be based on the existing rendering engine Webkit. Furthermore, it will include Google’s <a href="http://gears.google.com/">Gears</a> project.</li>

<li><strong>The browser will include a JavaScript Virtual Machine called V8</strong>, built from scratch by a team in Denmark, and open-sourced as well so other browsers could include it. One aim of V8 was to speed up JavaScript performance in the browser, as it’s such an important component on the web today. Google also say they’re using a “multi-process design” which they say means “a bit more memory up front” but over time also “less memory bloat.” When web pages or plug-ins do use a lot of memory, you can spot them in Chrome’s task manager, “placing blame where blame belongs.”</li>

<li>
<strong>Google Chrome will use special tabs.</strong> Instead of traditional tabs like those seen in Firefox, Chrome puts the tab buttons on the upper side of the window, not below the address bar.
<br><br>
<a href="/google-chrome/18"><img src=http://blogoscoped.com/files/google-chrome-tabs.png></a>
</li>

<li><strong>The browser has an address bar with auto-completion features.</strong> Called ’omnibox’, Google says it offers search suggestions, top pages you’ve visited, pages you didn’t visit but which are popular amd more. The omnibox (“omni” is a prefix meaning “all”, as in “omniscient” – “all-knowing”) also lets you enter e.g. “digital camera” if the title of the page you visited was “Canon Digital Camera”. Additionally, the omnibox lets you search a website of which it captured the search box; you need to type the site’s name into the address bar, like “amazon”, and then hit the tab key and enter your search keywords.</li>

<li><strong>As a default homepage Chrome presents you with a kind of “speed dial” feature, similar to the one of Opera.</strong> On that page you will see your most visited webpages as 9 screenshot thumbnails. To the side, you will also see a couple of your recent searches and your recently bookmarked pages, as well as recently closed tabs.
<br><br>
<a href="/google-chrome/22"><img src=http://blogoscoped.com/files/google-chrome-home.png></a>
</li>

<li><strong>Chrome has a privacy mode; Google says you can create an “incognito” window “and nothing that occurs in that window is ever logged on your computer.”</strong> The latest version of Internet Explorer calls this InPrivate. Google’s use-case for when you might want to use the “incognito” feature is e.g. to keep a surprise gift a secret. As far as Microsoft’s InPrivate mode is concerned, people also speculated it was a “porn mode.”</li>

<li><strong>Web apps can be launched in their own browser window without address bar and toolbar.</strong> Mozilla has a project called <a href="/archive/2007-10-26-n61.html">Prism</a> that aims to do similar (though doing so may train users into accepting non-URL windows as safe or into ignoring the URL, which could increase the effectiveness of phishing attacks).</li>

<li><strong>To fight malware and phishing attempts, Chrome is constantly downloading lists of harmful sites.</strong> Google also promises that whatever runs in a tab is sandboxed so that it won’t affect your machine and can be safely closed. Plugins the user installed may escape this security model, Google admits.</li>

</ul>

<p>This looks like a very interesting project, and I think it can’t hurt to have more competition in the browser area. Google is playing this as nicely as possible by open-sourcing things, with perhaps part of the reason to try to defend against monopoly accusations – after all, Google already owns a lot of what’s happening <em>inside</em> the browser, and some may feel owning a browser too could be a little too much power for a single company (Google could, for instance, release browser features that benefit their sites more than most other sites... as can Microsoft with Internet Explorer). For now, until Chrome is released in a testable version, how much of the speed, stability and user interface promises will be fullfilled – and how much of the interface you’ll be able to configure in case you don’t like it – remains to be seen.</p>
