Thomas here (Node.js lead from Opbeat). Don't worry, we are not closing down Opbeat :) We'll continue to run the current version of Opbeat via opbeat.com until we can port users to the new Elastic APM product that we are currently developing
Personally I'm a huge believer of open source, and Elastic is an open source company. That's one of the reasons why I'm super exited about this. I think this move will benefit everyone :)
I'm curious then why Opbeat itself was never open source?
Do I understand you right in that the plan is to make Elastic APM open source?
