If you move to the Couch ecosystem, you'll also have the option to use Couchbase Lite for iOS, Android, .NET, etc. As well as Sync Gateway which has dynamic fine grained permissions. Of course the whole ecosystem is open source under the Apache license.

What's the Couch ecosystem look like these days?

I poked around with CouchDB over the Christmas holiday but it seemed kinda dead. Is Couchbase still going strong?

It's quite active, though most development is going into the 2.0 release (which adds things like clustering). Here's the alpha if you're interested. https://couchdb-ci.s3-eu-west-1.amazonaws.com/release-candid...

Cool, is there an ETA on 2.0?

I remember not being able to find much of a roadmap when I was doing this evaluation, but that's probably just my fault.

Don't think there's an ETA, but there's a list of issues which are blocking the release. https://issues.apache.org/jira/browse/COUCHDB-2932?jql=proje...

FWIW, it shouldn't be difficult to upgrade from 1.x to 2.0 as you'll be able to replicate from a single-node database to a clustered database.

Yes see the other comments here and the comments on the Parse announcement. Couchbase Mobile is being used by major airlines as well as General Electric. And a bunch of start ups and other brands.
