DJ Checkup

Overview

DJ Checkup is a security scanner for Django sites. This package provides a command-line interface to run the security checks against your Django site. These are the same checks that are used by the DJ Checkup website at https://djcheckup.com.

Installation

This works best when installed with pipx or uv tool.

# With pipx:
pipx install djcheckup

# Or with uv:
uv tool install djcheckup

With uv, you can also run the tool without installing it first:

# With uvx:
uvx djcheckup https://yourdjangosite.com

Usage

Run the djcheckup command-line utility with the URL of your Django site. This will make several outbound requests from your computer to the website you are checking.

After a few seconds, you'll see a nicely formatted report in your terminal:

Advanced Usage

If you are trying to scan a website that uses a self-signed SSL certificate, or has another SSL issue that you want to ignore, you can pass the --insecure flag to the command. This tells the HTTP client to ignore SSL errors.

If you want to return the output in JSON format, you can pass the --output-json flag to the command. This will output a JSON response in your terminal which can be copied/pasted or piped into a file or other tools.

API

The djcheckup library can also be imported into your own code as a library so you can incorporate the results into your own tools.

In the following basic example, result is a SiteCheckResultDict typed dictionary. See outputs.py for implementation details:

from djcheckup import run_checks

result = run_checks("https://example.com")

When using djcheckup programmatically, you can swap out the HTTP client with your own client with any specific configuration you require. By default, DJ Checkup uses the Requests library. You can create your own Requests session with custom configuration and pass it to the run_checks method.

You can also change the output to return a JSON string response. See api.py for implementation details.

A full example could look like the following, which uses a custom Requests session and returns JSON:

import requests
from djcheckup import run_checks


client = requests.Session()
client.headers.update({"User-Agent": "My User Agent"})
client.verify = True

result = run_checks("https://example.com", client=client, output_format="json")

print(result)
