## What it is
Flask-Limiter is a Flask extension that adds rate limiting to Flask applications, with configurable limits at the app, blueprint, view, and route levels. It supports multiple storage backends such as Redis, Memcached, and MongoDB via the limits library.

## Use cases
- rate limit flask api endpoints
- throttle requests per user in flask
- add per-route rate limits to a flask app
- limit requests with redis-backed counters
- protect flask routes from abuse
- apply global rate limits to a flask application

## When to choose
- you have a Flask app and need request throttling
- you need distributed rate limiting backed by Redis or Memcached
- you want flexible limit scopes (app-wide, blueprint, route)

## When to avoid
- you use Django, FastAPI, or another non-Flask framework
- you need rate limiting outside a Flask/WSGI context
- you need API-gateway-level rate limiting rather than in-app

## Facets
- artifact type: library
- maturity: stable
- function: rate-limiting, middleware, web-framework
- domain: web-development, backend, apis, security
- platform: python
- tags: flask, flask-extension, redis, memcached, throttling, web-server
