Help someone with their computer.

Glass quick support is a free way to see and control someone's Mac, Windows or Linux computer from your browser, with nothing left installed on theirs. They run one line and read you a code. You see and control their screen from this browser, once they allow it. When they stop, nothing stays on their computer.

  1. They open Terminal and paste this On a Mac: Spotlight (⌘ Space), type Terminal. If they already have Glass, glass support does the same.
    curl -fsSL glassdesk.dev/help | sh
    On Windows: Start menu, type PowerShell, and paste this instead.
    irm glassdesk.dev/help | iex
  2. They read you their code Nine digits. The first time, their Mac asks them to allow Screen Recording and Accessibility for Glass.
  3. You type it here They're asked before you can see anything.

Each code works once, for an hour. The connection goes directly between the two computers and is end-to-end encrypted.

How it works

The line they paste downloads Glass into a temporary folder and starts it for this one session, with its own temporary settings and keys. It doesn't run as a background service or at login. Their code stands for a one-time link to their computer; glassdesk.dev keeps only a salted hash of it, and a code typed wrong too often is locked out. You connect over WebRTC, the same way as Glass's links from anywhere: direct and end-to-end encrypted, with no ports opened on their network.

What they see

The first time, their Mac asks them to allow Screen Recording and Accessibility, and the Glass window has a button for each. Before you see anything, they're asked to let you in. While you're connected the window stays open, and you can talk in a chat or draw on their screen to point at things. They click Stop sharing or close the window when you're done, and Glass deletes itself.

Questions

Does the person I'm helping have to install anything?

No. Glass runs from a temporary folder for this session only and is deleted when they stop sharing.

Can I see their screen without them knowing?

No. They're asked before you can see anything, the Glass window stays open while you're connected, and they can stop at any time.

Is it free?

Yes. Glass is free and open source under the MIT license, with no account for either of you.

Which computers does it work on?

The person being helped needs macOS 13 or later, or Linux on Wayland (beta). You can help from any modern browser: a Mac, a PC, an iPad or a phone. To reach your own computers every day, install Glass instead. For how this compares with TeamViewer, AnyDesk and Chrome Remote Desktop, see remote support without installing anything.
