Questions tagged [puma]

Puma is a simple, fast, threaded, and highly concurrent HTTP server for Ruby/Rack applications.

From the introduction:

Puma is a simple, fast, and highly concurrent HTTP 1.1 server for Ruby web applications. It can be used with any application that supports Rack, and is considered the replacement for Webrick and Mongrel. It was designed to be the go-to server for Rubinius, but also works well with JRuby and MRI. Puma is intended for use in both development and production environments.
