Flask-Bootstrap is an Flask app template for users to clone and customize as desired, as opposed to a Flask extension that you can install and use in your existing application.

This version of Flask-Bootstrap app template, v0.2.0, is a distinctly different version of the prior flask application template, now better organized using Flask blueprints. I think users will find this version much better suited for anything larger than the very smallest of server-side web apps.

Nonetheless, in the event that you'd like to use the old flask-bootstrap template, that version can now be found in the old_master branch.


  • Flask, including Flask-SQLAlchemy for user data and Flask-Login for authentication
  • Bootstrap 3
  • Webassets for easy Javascript deployment
  • Targeting OWASP web security standards
  • Python 2 and 3 support



Build Status


  • Install the system dependencies and Python dependencies
  • Customize your config/app.cfg (make create_cfg creates a basic config/local.cfg)
  • Fill out appropriate Makefile variables and run make
  • Then: python run.py or make run

Full installation instructions

The main system dependencies are Python, Postgreql, and their respective development packages. It could be easily adapted to run on MySQL or even SQLite, but the default installation instructions and Makefile below assume the use of PostgreSQL.


If you're on Ubuntu or Mint and you using Make, you're in luck. There is a very convenient Makefile to install and run the application (should work with Debian with a few minor changes). If you wish to use the Makefile, then simply fill in the appropriate config variables in the Makefile, run make install to install dependencies, and make run to start the application. The Makefile installation will even create a default local.cfg containing your project's configuration, for you to use and customize.

Otherwise, refer to the instructions below.

1. System dependencies:

On Ubuntu or Debian, first install:

sudo apt-get install postgresql python-dev libpq-dev

Red Hat, Fedora, and other derivatives are said to require (confirmation would be welcome):

yum install postgresql-devel postgresql-libs libpqxx-devel

Here's a brief article on getting these dependencies running on Windows (exact instructions would be welcome).

2. Python virtual environment and dependencies

It's probably a good idea to create a virtual environment for this project using virtualenv and virtualenvwrapper, which are installed using:

pip install virtualenvwrapper

Then, clone the repo, cd into it, and create a project virtual environment. I like to host my virtual environments in each project directory (but include it in the .gitignore so it's not gitable). So something like:

git clone git://github.com/esbullington/flask-bootstrap.git
cd flask-bootstrap
virtualenv venv
source venv/bin/activate

Once you have the virtual environment installed on your system, and the system dependencies, the rest is simple:

pip install -r config/requirements.txt


  • If you're using the Makefile, be sure to set your config filename
  • Otherwise, you can either:
    • pass your config file using python manage.py -c config/yourconfig.cfg runserver or else
    • set an environmental variable FLASK_APPLICATION_SETTINGS to point to your config file
  • Check to be sure your SECRET_KEY config setting is indeed secret and cryptographically strong (120+ bits of entropy)
  • The Makefile command make create_cfg sets this SECRET_KEY automatically as part of the config creation


make test or python manage.py testall
