A growing system

Using REI3 you get access to a growing ecosystem of business applications. While we will charge for optional services like software support in the future, REI3 is and will stay free to use. There are no plans for user limits or other, complex license models.

All current and future applications benefit from the growing feature set of the REI3 platform. LDAP authentication & authorization, CSV handling, ICS calendar access, email processing, change histories, integrated backups and many more features are already available. Many more will come.
