Mojolicious Build Status Windows build status

Back in the early days of the web, many people learned Perl because of a wonderful Perl library called CGI. It was simple enough to get started without knowing much about the language and powerful enough to keep you going, learning by doing was much fun. While most of the techniques used are outdated now, the idea behind it is not. Mojolicious is a new endeavor to implement this idea using bleeding edge technologies.


  • An amazing real-time web framework, allowing you to easily grow single file prototypes into well-structured MVC web applications.
    • Powerful out of the box with RESTful routes, plugins, commands, Perl-ish templates, content negotiation, session management, form validation, testing framework, static file server, CGI/PSGI detection, first class Unicode support and much more for you to discover.
  • A powerful web development toolkit, that you can use for all kinds of applications, independently of the web framework.
    • Full stack HTTP and WebSocket client/server implementation with IPv6, TLS, SNI, IDNA, HTTP/SOCKS5 proxy, UNIX domain socket, Comet (long polling), keep-alive, connection pooling, timeout, cookie, multipart, and gzip compression support.
    • Built-in non-blocking I/O web server, supporting multiple event loops as well as optional pre-forking and hot deployment, perfect for building highly scalable web services.
    • JSON and HTML/XML parser with CSS selector support.
  • Very clean, portable and object-oriented pure-Perl API with no hidden magic and no requirements besides Perl 5.22.0 (versions as old as 5.10.1 can be used too, but may require additional CPAN modules to be installed)
  • Fresh code based upon years of experience developing Catalyst, free and open source.


All you need is a one-liner, it takes less than a minute.

$ curl -L | perl - -M -n Mojolicious

We recommend the use of a Perlbrew environment.

Getting Started

These three lines are a whole web application.

use Mojolicious::Lite;

get '/' => {text => 'I ♥ Mojolicious!'};


To run this example with the built-in development web server just put the code into a file and start it with morbo.

$ morbo
Server available at

$ curl
I ♥ Mojolicious!

Duct tape for the HTML5 web

Use all the latest Perl and HTML features in beautiful single file prototypes like this one, and grow them easily into well-structured applications.

use Mojolicious::Lite;
use 5.20.0;
use experimental 'signatures';

# Render template "index.html.ep" from the DATA section
get '/' => {template => 'index'};

# WebSocket service used by the template to extract the title from a website
websocket '/title' => sub ($c) {
  $c->on(message => sub ($c, $msg) {
    my $title = $c->ua->get($msg)->result->dom->at('title')->text;


@@ index.html.ep
% my $url = url_for 'title';
  var ws = new WebSocket('<%= $url->to_abs %>');
  ws.onmessage = function (event) { document.body.innerHTML += };
  ws.onopen    = function (event) { ws.send('') };
