## Pricing
* $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](https://www.redmineup.com/pages/plugins/agile)). Prices vary.
