Everyone joins

One command with the partyline client — end-to-end encrypted. View-only by default; grant typing when you're ready.

partyline join <link>

Built for working together

Use-case image

Vibe-code as a team

Put your whole team in one AI coding session. Everyone sees the same agent and output and can jump in — with belay approvals, so a tool only runs when a human says go.

Use-case image

Incident war rooms

Spin up a shared terminal the moment something breaks. Responders watch the same shell, take turns driving, and paste input live — no screen-share lag.

Use-case image

Teach, learn, operate

Pair on code, run workshops, or do sysadmin work together — built for education, collaborative software, and ops teams.

Everything you need to share a shell

End-to-end encrypted

Sessions are encrypted end to end — only the people you share the link with can see them.

Humans + AI

Share a shell with people and steer an AI agent together.

Run anything

Not just code — any program, REPL, or tool you'd run in a shell.

You stay in control

Guests are view-only until you grant typing, with belay approvals for agent actions.

Join from anywhere

The relay gets teammates on the line through any network — encrypted end to end.

Teams & notifications

Orgs, roles, and email + Slack invites.

Open a line.

Get your team — and your AI — on the same terminal in seconds.
