horaa-tls 0.1.2

Advanced HTTP client with low-level TLS and browser fingerprint spoofing based on Go tls-client FFI

🌌 Horaa TLS

State-of-the-art in-process browser fingerprint emulation and HTTP client for Python.

horaa-tls is a high-performance HTTP client designed to evade anti-bot security layers (such as Cloudflare Turnstile, Akamai, Imperva, and DataDome). By interfacing directly with a precompiled Go-based BoringSSL networking backend via a ctypes FFI wrapper, it maintains a footprint indistinguishable from a real web browser at both the TLS socket and HTTP/2 layer.

⚙️ Installation

Install horaa-tls directly from PyPI:

pip install horaa-tls

💡 Why Horaa TLS?

• Zero External Dependencies: Automatically detects your OS and architecture, downloads the matching precompiled Go libraries, and initializes everything dynamically without requiring third-party pip dependencies.
• Cryptographic Emulation: Leverages preset browser profiles (Chrome 133, Firefox 133, etc.) to negotiate matching TLS extensions, cipher suites, key share curves, and HTTP/2 settings.
• Aligned User-Agents & Client Hints: Keeps HTTP/2 Client Hints (Sec-Ch-Ua, Sec-Ch-Ua-Mobile, Sec-Ch-Ua-Platform) perfectly aligned with the selected browser TLS version to prevent anti-bot detection signals.
• Decoupled Middleware Hooks: Register asynchronous or synchronous middleware layers (such as rotators and retries) directly in the request-response cycle.

🚀 Quick Start (The One-Minute Tour)

Initialize a session mimicking a Chrome 133 browser:

from horaa_tls import Session, ClientProfile

# Create a stateful, browser-emulating session
session = Session(profile=ClientProfile.CHROME_133)

try:
    # Perform a request (headers, JA3/JA4, and Client Hints are automatically injected)
    response = session.get("https://httpbingo.org/get")
    print(f"Status Code: {response.status_code}")
    print(response.json())
finally:
    # Always close the session to release low-level FFI memory allocations
    session.close()

🛠️ Core Concepts & Advanced Guide

🧬 Aligned Browser Profiles

horaa-tls currently offers pre-configured emulation profiles:

• Chrome Series: chrome_103, chrome_110, chrome_120, chrome_133
• Firefox Series: firefox_117, firefox_123, firefox_133
• Safari Series: safari_16_0, safari_ios_17_0
• Opera Series: opera_90

🏗️ Stateful Middleware Pipeline

You can easily intercept, modify, or retry requests using the built-in middleware engine. Registering rotators or exponential backoffs is straightforward:

from horaa_tls import Session, ClientProfile
from horaa_tls.middleware.proxy import ProxyRotatorMiddleware
from horaa_tls.middleware.retry import RetryMiddleware

session = Session(profile=ClientProfile.CHROME_133)

# 1. State-aware proxy rotator with failover recovery
proxies = ["http://proxy1.example.com:8080", "http://proxy2.example.com:8080"]
session.middleware_pipeline.register(
    ProxyRotatorMiddleware(proxies=proxies, mode="failover", max_failovers=3)
)

# 2. Exponential backoff retry handler for transport/network drops
session.middleware_pipeline.register(
    RetryMiddleware(max_retries=3, backoff_factor=2.0, status_forcelist=[500, 502, 503, 504])
)

# Request executes automatically through the middleware pipeline
res = session.get("https://httpbingo.org/get")
session.close()

📦 Session Snapshots (Persistence)

Export and restore session states (cookies, custom headers, active proxies, and middleware indicators) to distribute scraper instances across servers or queues:

# Save current state
session_state_json = session.to_json()

# Recreate an identical session in a different worker/process
restored_session = Session.from_json(session_state_json)

🍪 Direct FFI Cookie Management

Interact directly with the Go-layer cookie jar for fine-grained token/session management:

# Read active cookies stored in the Go memory layer
cookies = session.get_cookies_from_backend("https://example.com")

# Inject cookies directly into the Go-layer FFI engine
session.add_cookies_to_backend("https://example.com", [
    {"name": "session_token", "value": "token_value", "domain": ".example.com", "path": "/"}
])
