The modern and developer centric Python web framework that strives for an actual batteries included developer tool with a lot of out of the box functionality with an extremely extendable architecture. Masonite is perfect for beginner developers getting into their first web applications as well as experienced devs that need to utilize the full potential of Masonite to get their applications done.

Masonite works hard to be fast and easy from install to deployment so developers can go from concept to creation in as quick and efficiently as possible. Use it for your next SaaS! Try it once and you’ll fall in love.

  • Easily send emails with the Mail Provider and the SMTP and Mailgun drivers.

  • Send websocket requests from your server with the Broadcast Provider and Pusher and Ably drivers.

  • IOC container and auto resolving dependency injection.

  • Service Providers to easily add functionality to the framework.

  • Extremely simple static files configured and ready to go.

  • Active Record style ORM called Orator.

  • An extremely useful command line tool called craft commands.

  • Extremely extendable.

These, among many other features, are all shipped out of the box and ready to go. Use what you need when you need it.


In order to use Masonite, you’ll need:

  • Python 3.4+

  • Latest version of OpenSSL

  • Pip3

All commands of python and pip in this documentation is assuming they are pointing to the corresponding Python 3 versions. If you are having issues with any installation steps just be sure the commands are for Python 3.4+ and not 2.7 or below.


If you are running on a Linux flavor, you’ll need the Python dev package and the libssl package. You can download these packages by running:

Debian and Ubuntu based Linux distributions

$ sudo apt-get install python-dev libssl-dev python3-pip

Or you may need to specify your python3.x-dev version:

$ sudo apt-get install python3.6-dev libssl-dev python3-pip

Enterprise Linux based distributions (Fedora, CentOS, RHEL, ...)

# dnf install python-devel openssl-devel

Masonite excels at being simple to install and get going. We use a simple command line tool that will become your best friend. You’ll never want to develop again without it. We call them craft commands.

We can download our craft command line tool by just running:

$ pip install masonite-cli --user

If you already have craft installed, Masonite 2.2 requires masonite-cli>=2.2.0 so you may have to run with the upgrade flag too.

$ pip install masonite-cli --upgrade

If you are having installation issues, be sure to read the Known Installation Issues documentation.

Creating Our Project

Great! We are now ready to create our first project. We should have the new craft command. We can check this by running:

$ craft

This should show a list of command options. If it doesn't then you may have installed the masonite cli incorrectly. Try uninstalling it and be sure when you install it you install it with a --user flag like pip install masonite-cli --user.

We are currently only interested in the craft new command. To create a new project just run:

$ craft new project_name
$ cd project_name

This will get the latest Masonite project template and unzip it for you. We just need to go into our new project directory and install the dependencies in our requirements.txt file.

Activating Our Virtual Environment (optional)

You can optionally create a virtual environment if you don't want to install all of masonite's dependencies on your systems Python. If you use virtual environments then create your virtual environment by running:

$ python -m venv venv
$ source venv/bin/activate

or if you are on Windows:

$ python -m venv venv
$ ./venv/Scripts/activate

The pythoncommand here is utilizing Python 3. Your machine may run Python 2 (typically 2.7) by default for UNIX machines. You may set an alias on your machine for Python 3 or simply run python3anytime you see the pythoncommand.

For example, you would run python3 -m venv venv instead of python -m venv venv

Installing Our Dependencies

Now lets install our dependencies. We can do this simply by using a craft command:

$ craft install

This command is just a wrapper around the pipcommand. This installs all the required dependencies of Masonite, creates a .env file for us, generates a new secret key, and puts that secret key in our .env file. After it’s done we can just run the server by using another craft command:

Running The Server

After it’s done we can just run the server by using another craft command:

$ craft serve

Congratulations! You’ve setup your first Masonite project! Keep going to learn more about how to use Masonite to build your applications.

The Masonite CLI (also known as craft) will try to find all the commands in your project but may not be able to. In this case you will need to call craft directly using something like:

$ python craft serve

You can learn more about craft by reading The Craft Command documentation or continue on to learning about how to create web application by first reading the Routing documentation

Masonite has romantic versioning instead of semantic versioning. Because of this, all minor releases (2.0.x) will contain bug fixes and fully backwards compatible feature releases. Be sure to always keep your application up to date with the latest minor release to get the full benefit of Masonite's romantic versioning.
