Sinatra
Minimal Ruby DSL for building web applications — route definitions in a handful of lines, no MVC overhead.
Sinatra’s domain-specific language maps HTTP verbs and paths to blocks of code — a complete API can fit in a single file. It influenced Flask, Express, and a generation of micro-frameworks. For Ruby services where Rails’ weight is unnecessary, Sinatra remains the clean, minimal choice.
