Flask-Limiter

Flask-Limiter provides rate limiting features to flask routes. It has support for a configurable backend for storage with current implementations for in-memory, redis and memcache.

Quickstart

Add the rate limiter to your flask app. The following example uses the default in memory implementation for storage.

from flask import Flask
from flask_limiter import Limiter

app = Flask(__name__)
limiter = Limiter(app, global_limits=["2 per minute", "1 per second"])

@app.route("/slow")
@limiter.limit("1 per day")
def slow():
    return "24"

@app.route("/fast")
def fast():
    return "42"

@app.route("/ping")
@limiter.exempt
def ping():
    return 'PONG'

app.run()

Test it out. The fast endpoint respects the global rate limit while the slow endpoint uses the decorated one. ping has no rate limit associated with it.

$ curl localhost:5000/fast
42
$ curl localhost:5000/fast
42
$ curl localhost:5000/fast
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
<title>429 Too Many Requests</title>
<h1>Too Many Requests</h1>
<p>2 per 1 minute</p>
$ curl localhost:5000/slow
24
$ curl localhost:5000/slow
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
<title>429 Too Many Requests</title>
<h1>Too Many Requests</h1>
<p>1 per 1 day</p>
$ curl localhost:5000/ping
PONG
$ curl localhost:5000/ping
PONG
$ curl localhost:5000/ping
PONG
$ curl localhost:5000/ping
PONG
