Build your shield

Safe rooms for browsing and Zoom.

Liminal Shield builds a terminal command for two communities: general people who need Desktop or Chrome isolation, and Zoom people who need a safe participant, co-host, or complete host plus co-host setup.

General people

Safe places to browse or work.

Use these when the goal is simple isolation from everyday system activity.

  • Desktop: empty safe room, local demand 1/4
  • Chrome: isolated browser, local demand 2/4

Zoom people

Participant, co-host, or complete host setup.

Use these when Zoom is the room and the shield needs to protect how someone joins or hosts.

  • Participant: Zoom Chrome or Zoom Desktop
  • Co-host: browser-only ShieldBot
  • Complete: local host plus separate co-host

1. What kind of shield?

General people usually choose ShieldHuman. Zoom co-hosts use ShieldBot. Complete Zoom bundles host and co-host.

2. What do you need?

The command changes as you choose the room.

3. Storage

Humans can save work. Bots stay ephemeral.

4. Camera and microphone

ShieldBot always has camera and microphone stripped at the container boundary.

General is Desktop or Chrome.

For everyday isolation, choose the lightest room that does the job: Desktop first, Chrome when a browser is needed.

Zoom has three paths.

Join as a participant, run a protected co-host, or start Complete when the host and co-host should launch together.

The command is the contract.

The site only builds commands. The container runs locally on the user's machine through Docker.

Ports are automatic.

The launcher starts at 8080 and moves to the next free local port when needed.

AI assist ready

Need help choosing? Ask an AI to read this page.

This page is optimized so an assistant can explain the choices, compare local demand, and help you copy the right command.

  • Tell it what you want to do: browse, use a desktop, host Zoom, or add a co-host.
  • Tell it whether you want disposable storage, a save folder, or a persistent workspace.
  • For the shortest context, send it /ai-context.txt.

Two run paths

Use the path that matches your trust.

The terminal path is transparent and inspectable. The Mac app path is for people who trust Jeremy and want double-click simplicity.

Transparent terminal

Copy the generated command, inspect it yourself or with an AI, then run it in Terminal. This is the best path for people who do not already know Jeremy.

Available now

Signed Mac app

A Developer ID signed and notarized app can create the same launcher with double clicks on macOS. This is the community path: simpler, but it asks you to trust Jeremy's developer identity.

Prepared for signing

Product map

Two communities, one command builder.

ShieldHuman Desktop

A safe empty desktop for running work away from the everyday system.

  • Human controlled
  • Optional save folder or persistent workspace
  • Camera and mic are opt-in when the host can pass them through

ShieldHuman Chrome

A safe Chrome for browsing any website without using the normal browser profile.

  • Fresh profile by default
  • No host folders mounted unless selected
  • Runs in a lightweight isolated desktop

ShieldHuman Zoom

A human Zoom workspace, either through Zoom web in Chrome or Zoom for Linux inside a shielded desktop.

  • Chrome mode for Zoom web
  • Desktop mode for Zoom for Linux inside the shield
  • Can run next to a separate ShieldBot co-host

ShieldBot Zoom Co-host

A browser-only Zoom participant for host-authorized chat monitoring.

  • No camera or microphone at container and browser levels
  • No persistent storage
  • Session-local participant references only

Shield Zoom Complete

Complete means host plus co-host. Hosting is local only; co-host is Chrome only.

  • Host choice: Chrome, Shield Zoom App, or Mac Zoom App
  • Co-host choice: Local Chrome or cloud server Chrome
  • One launcher starts the chosen pair

Complete for community hosts

A simple setup for someone hosting Zoom who wants a co-host helping protect the room.

  • The human host stays local
  • The co-host is a separate bot participant
  • The bot has no camera, no microphone, and no persistent chat storage

Shield Zoom Complete for Mac

A native macOS launcher can open the real Zoom app for the host and start the protected co-host separately.

  • Host: macOS Zoom.app
  • Co-host: local ShieldBot Chrome or server co-host
  • Best community path after Developer ID signing and notarization
