Thank you! Means a lot, been working on this in the dark for a very long time (I originally though it might be paid version of Grafana). Really great to have the code public and show of some of the great things the backend will enable.
Yes, everything will be open source. Thanks to Grafana sponsors and me being part of the Raintank company that will provide SaaS and support services around Grafana and other existing open source monitoring/metrics projects as well as new components that we are working on (all open source!)
