# Kemal [](https://travis-ci.org/sdogruyol/kemal)

Lightning Fast, Super Simple web framework for Crystal. Inspired by Sinatra but with superior performance and built-in WebSocket support.

Kemal is under heavy development and currently supports Crystal latest.

Super Simple ⚡️

require "kemal"

# Matches GET "http://host:port/"
get "/" do
  "Hello World!"
end

# Creates a WebSocket handler.
# Matches "ws://host:port/socket"
ws "/socket" do |socket|
  socket.send "Hello from Kemal!"
end

Build and run!
