Google just released their new offline-webapp Firefox and Internet Explorer plugin called Google Gears.

It’s basically offers a persistent relational database that you can access from Javascript, as well as way to run Javascript code asynchronous, which is important if you have run expensive code.

We now have Firefox itself, Google, Adobe and Microsoft offering ways to take web applications offline. Google’s offer is quite easy to integrate into your site and I guess as soon Google starts to use it in their own applications many people will have it installed in their browser.

As they have released it under the BSD license I wonder if they can get Mozilla to integrate it in their browsers, but it seems unlikely because Firefox 3.0 will feature a similar feature on it’s own. But they could still distribute it with other applications Google offers.
