Python binding for curl-impersonate fork via cffi. A http client that can impersonate browser tls/ja3/http2 fingerprints.

primp

HTTP client that can impersonate web browser tls/http2 fingerprints

rnet

An ergonomic, censorship-resistant Python HTTP Client

httpmorph

httpmorph is a drop-in replacement for Python's requests library that uses a custom C implementation with BoringSSL instead of Python's standard HTTP stack.

wreq

An ergonomic, censorship-resistant Python HTTP Client

pyreqwest-impersonate

HTTP client that can impersonate web browser tls/http2 fingerprints
