Features

Token bucket rate limiting, for limiting requests/second with optional bursting behavior.
Quota-based rate limiting (e.g. requests/day)
Ability to configure different usage tiers, to give different users different rates/quotas.
Ability to configure different 'zones' so that different API methods can have different limits. (e.g. some particularly computationally expensive queries can have a much lower limit than cheap GET queries)
Provided views for very simple email-based API key registration.

simplekeys currently supports Django 1.8 through Django 1.11. Future versions will drop support for Django <= 1.10.
simplekeys is tested against Python 2.7, Python 3.5, and Python 3.6.
