Airtime Pro is our newer, hosted version of Airtime, our award-winning radio automation software.
Airtime Pro has several features that are not yet included in the open source version, such as a TuneIn integration, Facebook and Twitter plugins, webstreams and podcasting among others.
You can find the current pricing plans for Airtime Pro here: (https://www.airtime.pro/pricing). All our plans include a Radio Page and ticketing support during regular office hours (Monday through Friday from 7:00 - 22:00 UTC, except on German and Canadian holidays), as well as LiveChat support.
Airtime 184.108.40.206 is open source and installs on Ubuntu 14.10, 14.04 LTS, 13.10, 12.04 LTS, and Debian 7.8. It is available for free download here: https://www.sourcefabric.org/en/airtime/download/
As noted above, the open source version of Airtime does not include all features included in the Pro version. We don't currently have a fixed date for the next open source release.
