+## What users say about Alba
+
+> Alba is a well-maintained JSON serialization engine, for Ruby, JRuby, and TruffleRuby implementations, and what I like in this gem - except of its speed, is the easiness of use, no dependencies and the fact it plays well with any Ruby application!

+> Alba is more feature-rich and pretty fast, too
