Open source · Public beta
Control your coding agents from your phone.
Prompt Codex, Claude, or Cursor, run terminal commands, and take over your Mac's screen — approvals included — from anywhere.
A demonstration of one session: a prompt is sent to Codex from the phone and appears on the Mac; a terminal command is run; a prompt is sent to Claude Code; then the Mac's screen is shared to the phone, where a permission request is approved with one tap.

brew install --cask datawithfurkan/glasstunnel/glasstunnelQuestions, answered plainly
Before you open the tunnel.
Does my project move to the cloud?
Your project and coding tools continue running on your Mac. Remote-session content, including code shown in chat or on screen, can leave the Mac through WebRTC or the hosted relay.
What can the hosted service see?
The hosted relay can read prompts, chat, tool output, remote commands, attachments, and JPEG screen fallback frames. It caches recent transcript snapshots and processes account and connection metadata. WebRTC traffic is separately end-to-end encrypted. The hosted relay is not.
Which coding agents are supported?
Mac Screen and scoped Terminal are Supported. Codex, Cursor, Gemini CLI, and OpenCode integrations are available as Preview paths. Claude Code and generic mirroring are Experimental.
Does my Mac need to stay awake?
Yes. Glasstunnel includes an optional Keep Mac Awake setting for remote availability, but the Mac must remain powered on and connected.
Do I need an iPhone app?
No. The phone experience is an installable web app that runs in Safari or Chrome at app.glasstunnel.io.
Can I self-host it?
Yes. The repository includes self-hosting documentation for the signaling and TURN path, plus local development infrastructure.
Why are macOS permissions required?
Screen Recording lets Glasstunnel capture the screen or selected window. Accessibility allows approved remote prompts, text, and clicks to reach local coding apps.
How do updates work?
Glasstunnel does not silently update itself. Download a newer release from GitHub or run brew update followed by brew upgrade --cask datawithfurkan/glasstunnel/glasstunnel.
