Package Exports

gatekeeper-shell
gatekeeper-shell/npm/run.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (gatekeeper-shell) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

🛡️ Gatekeeper Shell

A secure, collaborative, remote terminal wrapper for your POSIX-style shell. Share your terminal with guests — but you decide what runs.

🌐 Website: gatekeeper.vishalraut.me

🌟 What Is This?

Gatekeeper Shell is a Go-powered secure relay system that wraps your local terminal and exposes it safely to guests.

Role	Capabilities
Host	Full terminal ownership. keystone inputs go directly to shell stdin. Approves or denies guest commands before execution.
Guest	Interactive viewing. Can type commands, which are queued and only run once approved by the host.

✨ Features

🔒 Host-Gated Execution — Guests cannot execute commands without host confirmation.
⚡ Real-Time WebSockets — Seamless streaming of stdout/stderr directly to the browser UI.
📦 Zero-Install Client — Run hosts/guests instantly via npx gatekeeper-shell.
🖥️ Premium Glassmorphic Terminal — Modern UI with Dark Mode, customized typography, and window layout.
📊 Relaying Observability — Built-in /health and /stats JSON endpoints on the relay server.
🛡️ Provenance Signed — Verified cryptographic builds published directly to npm registry.

🚀 Quick Start (Using npm)

To host a session instantly using the pre-compiled binary wrapper:

npx gatekeeper-shell

To run the client as a guest or target a self-hosted relay server:

# Join a session
npx gatekeeper-shell join <session-code>

# Connect using a custom relay server
npx gatekeeper-shell host --server wss://your-relay-server.com/ws

🛠️ Self-Hosting the Relay Server

If you want to deploy your own secure relay server (e.g. on Render, Fly.io, or Heroku):

1. Build and Run Server

go run ./cmd/server

The server starts at http://localhost:8080 by default.

2. Connect CLI Client to Server

go run ./cmd/cli host --server ws://localhost:8080/ws

📊 Observability

The relay server exposes JSON metrics endpoints for standard health checks and performance monitoring:

GET /health: Returns uptime, active session count, total client connections, and application version.
GET /stats: Lists metadata on active rooms, including active guest counts and cumulative traffic indicators.
