AnonRateThrottle in Django Rest Framework: Manage Unauthenticated Requests

In the realm of Django Rest Framework (DRF), effective API rate limiting is crucial to ensure fair usage and prevent abuse. Among the arsenal of built-in throttling classes, the AnonRateThrottle stands out as a powerful tool for controlling the rate of unauthenticated requests to your API endpoints. In this blog, we’ll delve into the details of AnonRateThrottle and provide a comprehensive example to help you implement it effectively.

Built-in Throttling Classes in DRF:

DRF offers several built-in throttling classes that you can use based on your requirements:

  1. AnonRateThrottle: Limits requests for unauthenticated (anonymous) clients.
  2. UserRateThrottle: Sets rate limits based on the authenticated user making the requests.
  3. ScopedRateThrottle: Allows you to define rate limits for specific views or groups of views.

What is AnonRateThrottle?

The AnonRateThrottle is a DRF throttling class designed to limit the rate at which unauthenticated (anonymous) clients can make requests to your API. It’s an invaluable tool to prevent potential abuse, malicious attacks, and undue strain on your server’s resources from unauthorized sources.

Implementing AnonRateThrottle:

To put theory into practice, let’s walk through an example of how to implement AnonRateThrottle in a DRF project.

Step 1: Setting Up Throttling in Settings

In your file, configure the AnonRateThrottle as the default throttling class:

        'anon': '5/minute',  # Allow 5 requests per minute for anonymous clients

Step 2: Applying Throttling to a View

Create a view that you want to protect using AnonRateThrottle:

from rest_framework.views import APIView
from rest_framework.response import Response

class ProtectedView(APIView):
    def get(self, request):
        data = {'message': 'This is a protected view for authenticated users.'}
        return Response(data)

By setting up the throttling class in your settings, any view that uses the ProtectedView class will automatically be throttled using AnonRateThrottle for unauthenticated requests.


The AnonRateThrottle in Django Rest Framework is an indispensable tool for maintaining control over unauthenticated requests to your API. By setting appropriate rate limits, you can ensure fair usage and prevent unauthorized clients from causing disruptions or overloading your server.

Implementing AnonRateThrottle enhances your API’s security and reliability, contributing to an improved user experience for both authenticated and anonymous users. Remember that effective rate limiting is an essential aspect of API management that helps strike a balance between accessibility and protection.
