alternativeto.net

The site alternativeto.net just came up on my radar through some of the regular feeds.  It is very reminiscent of osalt.com (Open Source as Alternative) which basically takes care of documenting lesser known software alternatives to their more popular counterparts.  You just type in the name of the software you want an alternate to and it will list you some suggestions.    It is also great when you are looking for replacing a piece of software that is no longer available or outdated.

While alternativeto.net doesn't only focus on open source it does offer more regular updates and a wider variety of options.

From the website:

We have one mission: helping you find the right software for your computer or mobile phone. To do this we wanted to rethink the whole process of searching for apps. No more browsing through categories with long lists of crappy software.

Based on our users recommendations we list great alternatives to the applications you want to replace. By joining the site you can participate in the process of making these recommendations better, so please join in!
