Though project management software is a commodity (if not customized), 37Signals’ Basecamp does a good job with the value add, though the web-based software is not sans problems (i.e . management notification of completed tasks and navigational quarks for starters). Enter ActiveCollab (in alpha), a free-open source PHP/MySQL alternative that is modeled closely after Basecamp and inspired from a blog post. You can install the platform on your own server and tweak it as you like, though it’s being reported that the alpha version is still buggy.
