This is a flask based blog whose frontend is created using bootstrap. If you have any questions or suggestions, feel free to open an issue or pull request :) Flask is a web application framework written in Python. Armin Ronacher, who leads an international group of Python enthusiasts named Pocco, develops it. Flask is based on Werkzeug WSGI toolkit and Jinja2 template engine. Both are Pocco projects.
