Catalyst

Catalyst is an open-source Perl MVC web framework that encourages rapid development and clean design without getting in your way by forcing rules. The catalyst-based app keeps things small and simple which gives users robustness and scalability. No complicated object hierarchies.When users write an app with Catalyst, users don't have to care much about session handling or authorization.

CPAN has a vast amount of power, which catalyst brings to users. Users can replace the default setup. There Is More Than One Way To Do It. Users can choose from a wealth of available models and views, drop in a bunch of plugins and create the setup that fits users best.

Catalyst uses a powerful database ORM like DBIx::Class for your model, plain old DBI or even LDAP and supports a wide range of models.Users may use whatever templating language: Template::Toolkit, Mason 2, HTML::Template and many more are fully supported.

Catalyst comes with its own lightweight test server for development. It automatically restarts when users’ sources have changed, so users get instant results.Catalyst 5.9 has native PSGI/Plack support which makes deployment for most webservers a no-brainer.
