Has anyone tried RTCode yet? Looks interesting but the homepage is a bit confusing as to whether it's a CodePen replacement with realtime support or can also be used for production?
RTCode is in private alpha. (Currently building Code Versions: diff, rollback, A/B testing; and Code Search: full-text search across all your active deployments).
Our playground and network have proven stable in production in several large enterprises for the last year.
I can answer any questions via email (support@elefunc.com) or chat (https://meet.elefunc.com).
