I'm not sure why you would use this over cowboy's REST handler. Cowboy is the thing that powers Phoenix -- you really can't beat it for concurrent performance.

(Loïc of NineNines is an absolutely incredible guy that does a ton of really important work, and you all should consider supporting him at https://salt.bountysource.com/teams/ninenines)

you are comparing apples and oranges :) I would go in that way: -> compare cowboy with mochiweb and leptus with rooster.

Perhaps in part, yes. But cowboy does have a very powerful REST handler built into it that does a lot of the same things: https://ninenines.eu/docs/en/cowboy/2.1/guide/rest_flowchart...

PS: if anyone is interested in a language-agnostic artifact like cowboy's or webmachine's, see https://github.com/for-GET/http-decision-diagram
