- From a user on Quora > it's flexible, highly customizable, (you can choose between various templates, plugins, etc.) It's open source and free to use. [and] the user interface doesn't overwhelm you. > > Since it's highly customizable you really have to dig yourself into it at first in order to create a great experience for your team members and colleagues / clients
- $0 - Redmine is free and open source
- However, TCO can be high, as Redmine is similar to Jenkins, with lots of desired functionality available through plugins (944 as of 2018-10-17), some of which are maintained, and some of which are not.
- There are also companies which sell plug-in sets, for example to add Agile functionality (eg. RedmineUP Agile Plugin). Prices vary.
