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

An ergonomic and modular Python HTTP client for advanced and low-level emulation, featuring customizable TLS, JA3/JA4, and HTTP/2 fingerprinting capabilities, powered by wreq.

• Async and Blocking Clients
• Plain bodies, JSON, urlencoded, multipart
• Cookie Store
• Redirect Policy
• Original Headers
• Rotating Proxies
• Connection Pooling
• Streaming Transfers
• Zero-Copy Transfers
• WebSocket Upgrade
• HTTPS via BoringSSL
• Free-Threaded Safety
• Automatic Decompression

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

pip install asyncio rnet==3.0.0rc13

And then the code:

import asyncio
from rnet import Client, Emulation


async def main():
    # Build a client
    client = Client(emulation=Emulation.Safari26)

    # Use the API you're already familiar with
    resp = await client.get("https://tls.peet.ws/api/all")

    # Print the response
    print(await resp.text())


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

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, rnet provides fine-grained control over TLS and HTTP/2 extensions and settings for precise browser behavior emulation.

2. Device Emulation

Most browser device models share identical TLS and HTTP/2 configurations, differing only in the User-Agent string.
