True, I used to be really interested in Firebase and their set of products. But because of several pretty bad experiences related to vendor lock-in and (very) high prices I switched over to an open source alternative.
It might not be so well known, but I found http://www.deepstream.io to have a relatively similar feature set, without having to deal with bad support (if it bothers you, just fix it yourself) and high prices, since you are the one who picks what suits you best.
