A Django framework for application-layer rate limiting

Project description

a framework for implementing rate-limiting middleware for Django projects

CI Status PyPi


This package allows Django developers to define application-level rate-limiting rules. Often, these rules would be expressed as “max # requests within a defined time period”. E.g.:

  • an IP address may make at most 1500 requests/day

  • users with an OAuth access token may make 500 reads/hour and 200 writes/hour

You can also define leaky bucket-style rules:

  • Allow 10 requests per minute, then every 6 seconds thereafter.


  • Attach rules to specific views using a decorator

  • Supports multiple throttle configurations

  • Use Django’s cache layer as the storage backend, or use Redis scripting for production-ready atomic operations

  • Define request attributes to rate limit (e.g. remote IP address, username, HTTP header value, device fingerprint, etc.)

  • Application-level rate limiting rules using fixed-bucket or generic cell rate algorithm (leaky bucket)


  1. Install the library with pip:

    sudo pip install django-throttle-requests
  2. Add the directory throttle to your project’s PYTHONPATH.


  1. Insert the following configuration into your project’s settings:

        'default': {
            'ALGORITHM': 'fixed-bucket',  # Default if not defined.
            'BUCKET_INTERVAL':15 * 60,  # Number of seconds to enforce limit.
            'BUCKET_CAPACITY':50,  # Maximum number of requests allowed within BUCKET_INTERVAL
    # Where to store request counts.
    THROTTLE_BACKEND = 'throttle.backends.cache.CacheBackend'
    # Optional if Redis backend is chosen ('throttle.backends.redispy.RedisBackend')
    THROTTLE_REDIS_HOST = 'localhost'
    # Normally, throttling is disabled when DEBUG=True. Use this to force it to enabled.
  2. Use the @throttle decorator to enforce throttling rules on a view:

    from throttle.decorators import throttle
    def myview(request):
  3. Also works with class-based views:

    from django.views.generic import View
    from django.utils.decorators import method_decorator
    from throttle.decorators import throttle
    class TestView(View):
        def dispatch(self, *args, **kwargs):
            return super(TestView, self).dispatch(*args, **kwargs)
        def head(self, request):
        def get(self, request):
