Develop PSR-7 middleware applications in minutes!

mezzio builds on laminas-stratigility to provide a minimalist PSR-7 middleware framework for PHP, with the following features:


We provide two ways to install Mezzio, both using Composer: via our skeleton project and installer, or manually.

Using the skeleton + installer

The simplest way to install and get started is using the skeleton project, which includes installer scripts for choosing a router, dependency injection container, and optionally a template renderer and/or error handler. The skeleton also provides configuration for officially supported dependencies.

To use the skeleton, use Composer's

$ composer create-project mezzio/mezzio-skeleton 

This will prompt you through choosing your dependencies, and then create and install the project in the

Manual Composer installation

You can install Mezzio standalone using Composer:

$ composer require mezzio/mezzio

However, at this point, Mezzio is not usable, as you need to supply minimally:

  • a router.
  • a dependency injection container.

We currently support and provide the following routing integrations:

We recommend using a dependency injection container, and typehint against PSR-11 Container. We can recommend the following implementations:

  • laminas-servicemanager:
    composer require laminas/laminas-servicemanager
  • Pimple (see docs for more details):
    composer require laminas/laminas-pimple-config
  • Aura.Di (see docs for more details):
    composer require laminas/laminas-auradi-config

Additionally, you may optionally want to install a template renderer implementation, and/or an error handling integration. These are covered in the documentation.


Documentation is in the doc tree, and can be compiled using mkdocs:

$ mkdocs build
