coder/httpjail
httpjail is a cross-platform tool that monitors and restricts HTTP/HTTPS requests from processes using network isolation and transparent proxy interception.

httpjail runs a target process inside a restricted network environment, intercepting its HTTP and HTTPS traffic through a transparent proxy with TLS certificate injection. It evaluates each request against JavaScript rules or external programs to allow or block access, and can log requests for auditing. The tool supports Linux and macOS and is positioned as a sandboxing utility, commonly used to constrain AI coding agents and other automated processes.
