wreq

🚀 Help me work seamlessly with open source sharing by sponsoring me on GitHub

An ergonomic and modular Python HTTP Client for high-fidelity protocol matching, featuring customizable TLS, JA3/JA4, and HTTP/2 signature capabilities, powered by wreq.

Features

• Async and Blocking Clients
• Plain bodies, JSON, urlencoded, multipart
• HTTP Trailer
• Cookie Store
• Redirect Policy
• Original Header
• Rotating Proxies
• Connection Pooling
• Streaming Transfers
• Zero-Copy Transfers
• WebSocket Upgrade
• HTTPS via BoringSSL
• Free-Threaded Safety
• Automatic Decompression
• Certificate Store (CAs & mTLS)

Example

The following example uses the asyncio runtime with wreq installed via pip:

pip install wreq

And then the code:

import asyncio
from wreq import Client, Emulation


async def main():
    # Build a client
    client = Client(emulation=Emulation.Chrome153)

    # Use the API you're already familiar with
    resp = await client.get("https://pingly.us.kg/api/all")
    print(await resp.text())


if __name__ == "__main__":
    asyncio.run(main())

Behavior

1. HTTP/2 over TLS

Due to the complexity of TLS encryption and the widespread adoption of HTTP/2, browser fingerprints such as JA3, JA4, and Akamai cannot be reliably emulated using simple fingerprint strings. Instead of parsing and emulating these string-based fingerprints, wreq provides fine-grained control over TLS and HTTP/2 extensions and settings for precise browser behavior emulation.

2. Device Emulation

TLS and HTTP/2 fingerprints are often identical across various browser models because these underlying protocols evolve slower than browser release cycles. 100+ browser device emulation profiles are maintained in wreq.

Building

1. Platforms

• Linux(glibc/musl): x86_64, aarch64, armv7, i686
• macOS: x86_64,aarch64
• Windows: x86_64,i686,aarch64
• Android: aarch64, x86_64

2. Development

Install the BoringSSL build environment by referring to boringssl.

# on ubuntu or debian
sudo apt install -y build-essential cmake perl pkg-config libclang-dev musl-tools git
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
pip install uv maturin

uv venv
source .venv/bin/activate

# development
maturin develop --uv

# build wheels
maturin build --release

Benchmark

Outperforms requests, httpx, aiohttp, and curl_cffi according to our benchmark suite driven by pyperf, though results are for reference only as they vary by environment.
