Collabtive is web-based project management software.
The project was started in November 2007. It is open source software and provides an alternative to proprietary tools like Basecamp. Collabtive is written in PHP and JavaScript.

Collabtive is intended for small to medium-sized businesses and freelancers.
We offer commercial services for installation and customization of Collabtive.
It can also be installed on an internal server as well as in the cloud.
