My issues are kind of specific to the idiosyncrasies of my app. Its multi-tenant and two-sided (admins and applicants), so I had to kind of roll my own auth system on top of the existing one. The fact that I could do that really means that it’s flexible enough honestly.

Another issue is that it doesn’t expose a server.js file, so its hard to do stuff like integrate an APM.

Seems like a replacement for MeteorJS.
