⚡ urllib3.future is a powerful, user-friendly HTTP client for Python.
⚡ urllib3.future goes beyond supported features while remaining compatible.
⚡ urllib3.future brings many critical features that are missing from both the Python standard libraries and urllib3:

• Async.
• Task safety.
• Thread safety.
• Happy Eyeballs.
• Connection pooling.
• Client-side SSL/TLS verification.
• Highly customizable DNS resolution.
• File uploads with multipart encoding.
• DNS over UDP, TLS, QUIC, or HTTPS. DNSSEC protected.
• Helpers for retrying requests and dealing with HTTP redirects.
• Support for gzip, deflate, brotli, and zstd encoding.
• Support for Python/PyPy 3.7+, no compromise.
• HTTP/1.1, HTTP/2 and HTTP/3 support.
• Proxy support for HTTP and SOCKS.
• Detailed connection inspection.
• Multiplexed connection.
• Mirrored Sync & Async.
• Amazingly Fast.

urllib3.future is powerful and easy to use:

>>> import urllib3
>>> pm = urllib3.PoolManager()
>>> resp = pm.request("GET", "https://httpbin.org/robots.txt")
>>> resp.status
200
>>> resp.data
b"User-agent: *\nDisallow: /deny\n"
>>> resp.version
20

or using asyncio!

import asyncio
import urllib3

async def main() -> None:
    async with urllib3.AsyncPoolManager() as pm:
        resp = await pm.request("GET", "https://httpbin.org/robots.txt")
        print(resp.status)  # 200
        body = await resp.data
        print(body)  # # b"User-agent: *\nDisallow: /deny\n"
        print(resp.version)  # 20

asyncio.run(main())

Installing

urllib3.future can be installed with pip:

$ python -m pip install urllib3.future

You either do

import urllib3

Or...

import urllib3_future

Doing import urllib3_future is the safest option for you as there is a significant number of projects that require urllib3.

Notes

• It's a fork

⚠️ Installing urllib3.future shadows the actual urllib3 package (depending on installation order). The semver will always be like MAJOR.MINOR.9PP like 2.0.941, the patch node is always greater or equal to 900.

Support for bugs or improvements is served in this repository. We regularly sync this fork with the main branch of urllib3/urllib3 against bugfixes and security patches if applicable.

• OS Package Managers

Fellow OS package maintainers, you cannot just build and ship this package to your package registry. As it override urllib3 and due to its current criticality, you'll have to set:

URLLIB3_NO_OVERRIDE=true python -m build. Set URLLIB3_NO_OVERRIDE variable with "true" in it.

It will prevent the override.

Compatibility with downstream

You should always install the downstream project prior to this fork.

e.g. I want requests to be use this package.

python -m pip install requests
python -m pip install urllib3.future

Nowadays, we suggest using the package Niquests as a drop-in replacement for Requests. It leverages urllib3.future capabilities appropriately.
