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.

HTTPClient is a Ruby gem that provides a simple and flexible interface for making HTTP requests. It's a full-featured HTTP client library with support for cookies, redirects, proxy, and more. It's built on top of the libwww-perl library, which is a widely-used, robust and well-documented library.

Features:

  • methods like GET/HEAD/POST/* via HTTP/1.1.
  • HTTPS(SSL), Cookies, proxy, authentication(Digest, NTLM, Basic), etc.
  • asynchronous HTTP request, streaming HTTP request.
  • debug mode CLI.
  • by contrast with net/http in standard distribution;
  • Cookies support
  • MT-safe
  • streaming POST (POST with File/IO)
  • Digest auth
  • Negotiate/NTLM auth for WWW-Authenticate (requires net/ntlm module; rubyntlm gem)
  • NTLM auth for Proxy-Authenticate (requires 'win32/sspi' module; rubysspi gem)
  • extensible with filter interface
  • you don't have to care HTTP/1.1 persistent connection (httpclient cares instead of you)

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']}") ```
```ruby require 'httpclient' client = HTTPClient.new # GET requests response = client.get("http://httpbin.org/get") puts response.content # POST requests data = { name: "value" } response = client.post("http://httpbin.org/post", data) puts response.content ```
