Collabtive

Collabtive is an open-source project management tool founded in 2007 in Germany. It aims to simplify project management with a clean design and visual appeal. The tool caters to virtual teams through task, milestone, file, and message management, with the ability to track time worked on a task-by-task basis. Furthermore, it supports over 40 languages and is suitable for small to medium-sized businesses and freelancers, offering both cloud and internal server installation options. While the standard version is free, commercial services and plugins, such as project templates and Gantt charts, are also available. The development team, led by Eva Kiszka, Philipp Kiszka, and Marcus Fröhner, consists of dedicated volunteers. Collabtive is continually seeking contributors for coding, testing, translation, documentation, and support.
