**limits** is a python library for rate limiting via multiple strategies
with commonly used storage backends (Redis, Memcached & MongoDB).

The library provides identical APIs for use in sync and
`async <https://limits.readthedocs.io/en/stable/async.html>`_...

## AI interpretation — verify before relying

Implements rate limiting with multiple strategies (fixed window, moving window, sliding window counter) and storage backends (Redis, Memcached, MongoDB, in-memory) for both sync and async Python applications.

Verdict: Production-ready rate limiting library with solid maintenance, permissive licensing, and low install friction. Supports multiple strategies and backends suitable for both simple and distributed rate-limiting scenarios. No known vulnerabilities.
