Even if you've got an extremely original idea for a business, software or product, it's hard to succeed if you don't keep up with your competitors. Free web app Competitious helps you track your competition with collaborative feature comparisons, news feeds and more.
Whether your competition is a company or just a particular product, you can track all of your competitors at once with Competitious. You can build feature comparisons between you and your competitors, track the traffic of their websites (and your own), as well as share these things with your co-workers. You can clip and share web articles about you and your competition, as well as subscribe to the news feeds of your collaborators to keep up to date.
While Competitious offers a lot of great templates for these types of things, you have to enter all the information manually; this isn't a huge drawback, but could likely get tedious at times, especially during the initial set-up. However, the service is still in beta, so this and its other drawbacks (such as traffic reports only working for sites in the top 100,000 on Alexa) will likely be improved in future releases.
