Px is an HTTP/HTTPS proxy server that automatically handles NTLM and Kerberos proxy authentication, typically in corporate environments, using Windows SSPI single sign-on or configured credentials. It is a Python-based CLI tool built on libcurl that supports all libcurl authentication mechanisms.

Use cases

• authenticate through an NTLM corporate proxy
• use pip and git behind a corporate proxy that requires Windows authentication
• run a local proxy that handles Kerberos/NTLM handshake automatically
• configure proxy authentication with a PAC file
• bypass proxy for specific hosts while routing others through NTLM proxy
• run proxy authentication on Linux or macOS with domain credentials

When to choose

• you are behind a corporate NTLM/Kerberos proxy and tools cannot authenticate themselves
• you want single sign-on proxy auth using the logged-in Windows account
• you need a cross-platform proxy authenticator with PAC file support

When to avoid

• your proxy uses standard basic auth or no authentication
• you need a general-purpose forward proxy with caching or TLS inspection
• you need a GUI-managed proxy client
