curl_cffi is a Python binding for a curl-impersonate fork via cffi, providing an HTTP client that can impersonate browser TLS/JA3, HTTP/2, and HTTP/3 fingerprints. It serves as a drop-in alternative to requests or httpx when websites block requests based on client fingerprinting.
Use cases
- scrape websites that block requests based on TLS fingerprints
- make HTTP requests that look like a real Chrome browser
- bypass Cloudflare or Akamai bot detection in Python
- replace requests/httpx when getting blocked for no obvious reason
- send requests with custom JA3/JA4 fingerprints
- test HTTP/3 and QUIC fingerprint behavior
- debug TLS fingerprinting with a curl CLI
When to choose
- your Python HTTP requests are blocked by anti-bot systems like Cloudflare or Akamai
- you need browser-like TLS/JA3/HTTP2 fingerprints from Python
- you want a fast curl-based client with requests-like API
When to avoid
- you just need a simple HTTP client with no fingerprint requirements
- you need a pure-Python dependency without native binaries
- you target Python versions older than 3.10
