Tundra is an app that allows you to keep up-to-date with all your favourite websites on one page.

Tabs, columns and widgets Organize your online life into as many tabs and widgets as you want. You can have unlimited numbers of tabs and columns, and unlimited numbers of widgets per column. Each widget is fully configurable so you can have it just how you like it.
Auto refresh Each widget can automatically refresh (independently of both the page and other widgets) at any interval you'd like (or not at all) so you're always kept up-to-date.
Power at your fingertips Tundra includes a powerful command bar that lets you do more in less time. Right now, you can search using any search engine of your choice (either choose from a built-in selection or specify your own) but soon it'll support many more features.
Instant customisation Change the look of Tundra instantly with themes. Choose from a list of themes that have been made by someone else or make your own by uploading a CSS file and any resources your theme needs (documentation coming soon).
Viewing history Access Tundra on multiple browsers and get fustrated that you don't know what you've already seen? If you opt-in to the view history feature, Tundra will keep a log of the articles that you visit through RSS feeds so you never read one thing twice.
Developers, start your editors Tundra uses the latest web standards - HTML5 and CSS3. This allows Tundra to implement the latest features effortlessly so the experience is better for you - the user. Additionally, Tundra is written using the CodeIgniter and MooTools frameworks.
