The short version

Only CouchDB has a free tier, so it costs nothing to try first.
Each has a real cost: CouchDB append-only storage model may have performance implications for certain workloads with high update rates; Knack plans are priced by number of records and objects rather than users, ranging from $110 to $300 per month as data volume grows
