Mosaic

A simple blog system in the spirit of the IndieWeb. It's aimed to get up and running as quickly as possible with your own, easily customizable CMS

Installation

First, install the package using your favorite python package manager

uv add django-mosaic

or

pip install django-mosaic

Second, you need to enable the app in your Django project.

# settings.py
INSTALLED_APPS = [
  ...
  "django_mosaic"
  ...
]

Third, run the migrations to add the relevant schemas to your database

uv run python manage.py migrate

Quickstart

Start the development server.

uv run python manage.py runserver

Mosaic exposes all its features through the admin. First, create a user for the admin.

uv run python manage.py createsuperuser

Go to http://localhost:8000/admin.

You can write a post right within the admin, in markdown.

By default, there are two namespaces, public and private. Everything you post in public will be visible to, well, everyone. Posts in private will be visible only to those with a secret AccessToken, which you can also generate in the admin.

Only Posts with the is_draft flag set to False will be shown on your website.

Hit the save button and go to https://localhost:8000

Have fun!

Deployment

To reduce one of the major pains of running your own site, Mosaic includes automated deployment for VPS hosting with sane (reach out if not!) defaults for Docker, nginx, and SSL certificates.

Quick Deploy

Deploy to a fresh Ubuntu/Debian VPS:

uv run python manage.py mosaic deployment setup

The setup wizard will prompt you for:

• VPS hostname and SSH credentials
• Domain name
• Email for SSL certificate notifications

The deployment script will:

• Install Docker, nginx, and certbot
• Configure firewall (UFW)
• Build and deploy your application in a Docker container
• Set up nginx as a reverse proxy with rate limiting
• Obtain SSL certificates via Let's Encrypt
• Configure automated hourly database backups

Check Deployment Status

uv run python manage.py mosaic deployment status

Shows health checks for services, SSL certificates, backups, and application availability.

Configuration

Configuration is saved to .deployment-config.toml for subsequent runs.
