Lightning Fast, Super Simple web framework for [Crystal](http://www.crystal-lang.org).
Inspired by [Sinatra](http://www.sinatrarb.com/) but with superior performance and built-in WebSocket support.

Kemal is under heavy development and currently supports Crystal 0.9.1.

# Super Simple <3

```ruby
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!

```
crystal run src/kemal_sample.cr
```
Go to *http://localhost:3000*

Check [documentation](https://serdardogruyol.com/kemal) or [samples](https://github.com/sdogruyol/kemal/tree/master/samples) for more.
