hihi

hihi is a developer tool that provides a VPN-isolated sandbox environment for running AI command-line tools. It uses throwaway Docker containers where all traffic is routed through a VPN tunnel and an inspecting mitmproxy to prevent the user's real IP from leaking. The package bundles command-line tools such as claude, codex, copilot, gh, wrangler, ollama, agy, git, python3, and jq in an ephemeral shell that disappears when closed.

The software is distributed as a shell installer for macOS and Linux and requires Docker, bash, and curl to run. Users must add their Surfshark VPN_USER and VPN_PASS service credentials before running hihi up again to create the configuration file ~/.config/hihi/hihi.conf.

Users can run hihi up --mitm to enable HTTP(S) inspection, which gives each browser its own VPN and MITM. They can also use the standalone Claude Code with its own VPN without proxy inspection, or the hardened Chromium browser session at localhost:8083 with its own VPN and MITM.

The persistent gateway component manages the VPN tunnel and proxy, while the shared VPN gateway handles CLI traffic. Users can check VPN health with hihi status, inspect or reconnect the gateway, and rebuild tools that have changed using the update command.

The workspace around the project is disposable, meaning the container is removed when the session ends, but the mounted project and saved logins persist between sessions. Users can run hihi cli to open their workspace with familiar tools like Claude Code, Codex, Copilot, gh, wrangler, and hi already included.

Users can publish a port with the --port N flag or add a privileged session with its own Docker daemon using the --docker flag. They can also stop the gateway and remove containers with cleanup, or uninstall the software entirely with cleanup --unlink.

The website mentions that the demo host is ready for the first install and provides a simulated terminal where users can type help for all demo commands. It works on the machine and is already included inside hihi, so users do not need to download additional dependencies unless hi tells them what to install.

The software includes an optional hardened Chromium browser session and can be used with Cloudflare, Git, documents, files, and a Mac. It is designed to give a fresh sandbox for everyday jobs while keeping the project intact.

The listing description states that the software is distributed as a shell installer for macOS and Linux. It is designed for developers who need a disposable workspace connected through a VPN for running AI command-line tools.

The website provides a simulated host operating system for macOS and Linux, and the demo allows users to start with curl -fsSL hihi.sh | sh without needing any downloads, accounts, or real system commands.

The tool includes a persistent gateway component that manages the VPN tunnel and proxy, plus an optional hardened Chromium browser session with its own VPN and MITM.

The official website of hihi is hihi.sh.
