Demo request: edit a project file. Approve or Deny?

Interactive demo with fictional sessions. Select a session, then try the controls.

The profile

Your sessions and decisions in one place.

Find sessions by name

Recent sessions come first, labeled with the start of their name. Use one row each for Claude Code and Codex, or both rows for the active app.

See what needs your attention

A slow pulse highlights sessions waiting for your input. Status indicators show which sessions are working, ready, or waiting.

Respond to one session at a time

Select a session, review its request in the plugin settings, then use the dedicated keys to approve or deny that request.

Before you start

What to know.

Can I buy the plugin yet?

The plugin is in development. We plan a one-time purchase through Elgato Marketplace after validation. Email us to follow the release.

Do I need another account or subscription?

Your harnesses stay installed and signed in to your own accounts. Harness Control does not include model access; you continue to pay for your agent usage separately.

Do the same controls work in every app?

Each harness has its own confirmation interface. Opening a session also depends on the app and terminal. Cursor sessions must be opened manually; Pi requires enabling its extension.

Where does the plugin send data?

The plugin’s connections stay on your Mac. It does not read model-provider credentials. Your agents keep their usual connections.

Harness Control

Do you use several coding harnesses?

Email us to follow the launch or tell us about your setup. The first release is planned for macOS with a 15-key Stream Deck profile.
