Primp is a Python HTTP client that impersonates real web browsers by replicating their TLS fingerprints, HTTP/2 settings, and header ordering. It is a lightweight alternative to curl-cffi for bypassing TLS and HTTP fingerprinting-based bot detection.

Key features include:

  • Browser impersonation Can impersonate Chrome, Firefox, Safari, Edge, and OkHttp clients by replicating their exact TLS fingerprints (JA3/JA4), HTTP/2 frame settings, header ordering, and other connection-level characteristics.
  • HTTP/2 support Full HTTP/2 support with configurable settings that match real browser behavior.
  • Lightweight Smaller and simpler than curl-cffi while providing similar impersonation capabilities. Built on Rust for performance.
  • Familiar API Provides a requests-like API with Session support, making it easy to adopt for developers familiar with the Python requests library.
  • Proxy support HTTP and SOCKS5 proxy support with authentication.
  • Cookie management Automatic cookie handling across requests within a session.

Primp fills a similar niche to curl-cffi and hrequests — HTTP clients designed to avoid TLS/HTTP fingerprinting — but takes a Rust-powered approach for better performance. It is particularly useful when you need to bypass bot detection that relies on connection-level fingerprinting without using a full browser.

hrequests is a feature rich modern replacement for a famous requests library for Python. It provides a feature rich HTTP client capable of resisting popular scraper identification techniques: - Seamless transition between headless browser and http client based requests - Integrated HTML parser - Mimicking of real browser TLS fingerprints - Javascript rendering - HTTP2 support - Realistic browser headers

Example Use


```python import primp # Create a session that impersonates Chrome session = primp.Session(impersonate="chrome_131") # Make requests - TLS fingerprint matches real Chrome response = session.get("https://example.com") print(response.status_code) print(response.text) # POST with JSON data response = session.post( "https://api.example.com/data", json={"key": "value"}, ) # With proxy session = primp.Session( impersonate="firefox_133", proxy="http://user:pass@proxy.example.com:8080", ) response = session.get("https://example.com") # Different browser impersonation profiles for browser in ["chrome_131", "firefox_133", "safari_18", "edge_131"]: session = primp.Session(impersonate=browser) resp = session.get("https://tls.peet.ws/api/all") print(f"{browser}: {resp.json()['ja3_hash']}") ```
hrequests has almost identical API and UX as requests and here's a quick overview: ```python import hrequests # perform HTTP client requests resp = hrequests.get('https://httpbin.org/html') print(resp.status_code) # 200 # use headless browsers and sessions: session = hrequests.Session('chrome', version=122, os="mac") # supports asyncio and easy concurrency requests = [ hrequests.async_get('https://www.google.com/', browser='firefox'), hrequests.async_get('https://www.duckduckgo.com/'), hrequests.async_get('https://www.yahoo.com/'), hrequests.async_get('https://www.httpbin.org/'), ] responses = hrequests.map(requests, size=3) # max 3 conccurency ```
