Niquests Logo

Niquests is a simple, yet elegant, HTTP library. It is a drop-in replacement for Requests, which is under feature freeze.

Niquests, is the “Safest, Fastest[^10], Easiest, and Most advanced” Python HTTP Client. Production Ready!

✔️ Try before you switch: See Multiplexed in Action
📖 See why you should switch: Read about 10 reasons why, and "Revived the promise made six years ago for Requests 3"
✨ You were used to betamax, requests-mock, responses, ...? See how they still work! We got you covered.

📈 Look at the performance comparison against them!

Scenario: Fetch a thousand requests using 10 tasks or threads, each with a hundred requests using a single pool of connection.

High-Level APIs

Client Average Delay to Complete Notes
requests 987 ms or ~1013 req/s ThreadPoolExecutor. HTTP/1.1
httpx 720 ms or ~1389 req/s Asyncio. HTTP/2
niquests 340 ms or ~2941 req/s Asyncio. HTTP/2

Simplified APIs

Client Average Delay to Complete Notes
requests core 643 ms or ~1555 req/s ThreadPoolExecutor. HTTP/1.1
httpx core 490 ms or ~2000 req/s Asyncio. HTTP/2
aiohttp 210 ms or ~4762 req/s Asyncio. HTTP/1.1
niquests core 160 ms or ~6200 req/s Asyncio. HTTP/2

Did you give up on HTTP/2 due to performance concerns? Think again! Do you realize that you can get 3 times faster with the same CPU if you ever switched to Niquests from Requests? Multiplexing and response lazyness open up a wide range of possibilities! Want to learn more about the tests? scripts? reasoning?

Take a deeper look at https://github.com/Ousret/niquests-stats

>>> import niquests
>>> r = niquests.get('https://one.one.one.one')
>>> r.status_code
200
>>> r.headers['content-type']
'application/json; charset=utf-8'
>>> r.oheaders.content_type.charset
'utf-8'
>>> r.encoding
'utf-8'
>>> r.text
'{"authenticated": true, ...'
>>> r.json()
{'authenticated': True, ...}
>>> r
<Response HTTP/2 [200]>
>>> r.ocsp_verified
True
>>> r.conn_info.established_latency
datetime.timedelta(microseconds=38)

or using async/await!

import niquests
import asyncio

async def main() -> None:
    r = await niquests.aget('https://one.one.one.one', stream=True)
    print(r)  # Output: <Response HTTP/2 [200]>
    payload = await r.text  # we await text because we set `stream=True`!
    print(payload)  # Output: <html>...
    # or... without stream=True
    r = await niquests.aget('https://one.one.one.one')
    print(r)  # Output: <Response HTTP/3 [200]>
    payload = r.text  # we don't need to away anything, it's already loaded!
    print(payload)  # Output: <html>...

asyncio.run(main())

Niquests allows you to send HTTP requests extremely easily. There’s no need to manually add query strings to your URLs, or to form-encode your PUT & POST data — just use the json method!

Downloads Supported Versions OpenSSF Best Practices

This project does not require any compilation toolchain. The HTTP/3 support is not enforced and installed if your platform can support it natively (e.g. pre-built wheel available).

✨ Installing Niquests and Supported Versions

Niquests is available on PyPI:

$ python -m pip install niquests

Niquests officially supports Python or PyPy 3.7+.

🚀 Supported Features & Best–Practices

Niquests is ready for the demands of building scalable, robust and reliable HTTP–speaking applications.

📝 Why did we pursue this?

For many years now, Requests has been frozen. Being left in a vegetative state and not evolving, this blocked millions of developers from using more advanced features.

We don't have to reinvent the wheel all over again, HTTP client Requests is well established and really pleasant in its usage. We believe that Requests has the most inclusive and developer friendly interfaces. We intend to keep it that way. As long as we can, long live Niquests!

How about a nice refresher with a mere CTRL+H import requests to import niquests as requests ?

💼 For Enterprise

Professional support for Niquests is available as part of the Tidelift Subscription. Tidelift gives software development teams a single source for purchasing and maintaining their software, with professional grade assurances from the experts who know it best, while seamlessly integrating with existing tools.

Niquests is a highly improved HTTP client that is based (forked) on Requests. The previous project original author is Kenneth Reitz and actually left the maintenance of Requests years ago.

[^1]: aiohttp was conceived solely for an asynchronous context. [^2]: requests has no support for asynchronous request. [^3]: while the HTTP/2 connection object can handle concurrent requests, you cannot leverage its true potential. [^4]: loading client certificate without file can't be done. [^5]: httpx officially claim to be thread safe but recent tests demonstrate otherwise as of february 2024. https://github.com/jawah/niquests/issues/83#issuecomment-1956065258 https://github.com/encode/httpx/issues/3072 https://github.com/encode/httpx/issues/3002 and only recently acknowledged the issue in https://github.com/encode/httpx/issues/3324 (one year after getting valid reports). [^6]: they do not expose anything to control network aspects such as IPv4/IPv6 toggles, and timings (e.g. DNS response time, established delay, TLS handshake delay, etc...) and such. [^7]: while advertised as possible, they refuse to make it the default due to performance issues. as of October 2024 an extra is required to enable it manually. [^8]: they don't support HTTP/3 at all. [^9]: you must use a custom DNS resolver so that it can preemptively connect using HTTP/3 over QUIC when remote is compatible. [^10]: performance measured when leveraging a multiplexed connection with or without uses of any form of concurrency as of October 2024. The research compared httpx, requests, aiohttp against niquests. See https://github.com/Ousret/niquests-stats [^11]: enabled when using a custom DNS resolver. [^12]: available only when using HTTP/3 over QUIC and that the remote server support also the same post-quantum key-exchange algorithm. Also, the qh3 installed version must be >= 1.1. [^13]: most servers out there are not ready for this feature, but Niquests is already compliant and future-proof! Caddy server and HAProxy support this! [^14]: they don't offer any built-in to speak with a WebSocket server.
