anthropair

Pair-program with Claude, share your screen with a friend.

A local dashboard that wraps the Claude Code SDK for AI-assisted coding and adds LiveKit-powered screen sharing — all in one browser tab.

Features

🤖 AI Agent Chat

Conversational coding assistant powered by the Claude Code SDK. Streaming responses, session resumption, and per-message cost tracking so you always know what you're spending.

📁 File Browser

Lazy-loaded directory tree rooted in your working directory. Respects .gitignore automatically — click any file to view or send it as context to the agent.

📺 Screen Sharing

WebRTC screen sharing via LiveKit. Generate a room code, share it with a collaborator, and they see your screen in real time. Optional PiP webcam overlay included.

⚡ Quick Actions

Pre-built task buttons to skip the prompt writing: Explain · Fix Bug · Refactor · Write Tests · Code Review · Custom

✅ Task Queue

Every tool call the agent wants to make lands in an approval queue first. Approve or reject each operation before it runs. Multi-client broadcast keeps all connected browsers in sync.

🔒 Permission System

Tool-level approve/deny controls so the agent only touches what you allow. Review each action before it executes — no surprises.

⚙️ Settings

In-browser configuration panel. Manage environment variables, toggle features, and update secrets — values are masked by default.

Getting Started

1. Run it

npx anthropair

Or clone and run locally:

git clone <repo-url>
cd anthropair
npm install

2. Set environment variables

Create a .env file (or configure in the Settings panel):

Screen sharing is optional — it works without LiveKit keys.
