The aim of BitNami is to simplify the deployment of web applications, such as wikis or blogs, in order to make them more accessible. There are a lot of high quality open source software packages that aren't used as much as they could be because getting them up and running can be a complex process. BitNami changes that. It produces open source installers or software packages for web applications and solution stacks.
