graftcp is a Linux command-line tool that redirects TCP, UDP, and DNS traffic of arbitrary processes to SOCKS5 or HTTP proxies using ptrace syscall tracing, without relying on LD_PRELOAD. It works even on statically linked binaries like Go programs, and supports proxy selection modes, blacklists, and embedded DNS-over-TCP forwarding.

Use cases

• route a program's traffic through a SOCKS5 proxy without configuring it
• proxy statically linked Go binaries that proxychains can't handle
• redirect DNS queries through a proxy to avoid DNS leaks
• force specific processes through an HTTP proxy on Linux
• selectively proxy traffic while blacklisting some IPs to connect direct

When to choose

• you need to proxy statically linked binaries or programs that ignore LD_PRELOAD
• you want per-process proxying on Linux without a system-wide VPN
• you need UDP and DNS proxying alongside TCP through SOCKS5

When to avoid

• you need proxying on macOS or Windows, since graftcp is Linux-only
• you want transparent system-wide traffic redirection rather than per-process
• you need a GUI proxy client
