About Loopsy
Loopsy is an open-source tool that lets you control any terminal on your laptop from your phone, self-hosted on Cloudflare Workers. It connects your phone and laptop through a lightweight Cloudflare Worker relay using WebSockets, requiring no port forwarding, public IP, or VPN. It also enables agent-to-agent communication across machines on a LAN via MCP, allowing AI coding agents like Claude Code, Codex CLI, Gemini CLI, and Opencode to drive remote machines directly.
- Phone-to-terminal control: Install the npm package, deploy your relay in ~30 seconds with
npx @loopsy/deploy-relay, and pair your phone by scanning a QR code. - Full PTY support: Real terminal with ANSI rendering, scrollback, resize, and TUI support ā sessions persist across tab switches, lock screens, and signal loss.
- Voice input: Dictate commands via the Web Speech API directly from the mobile web app, with the ability to edit before sending.
- Self-hosted relay: Deploy your own Cloudflare Worker relay so no third party sees your terminal content; the free tier covers personal use comfortably.
- LAN agent-to-agent MCP tools: Daemons discover each other via mDNS and expose MCP tools (
loopsy_execute,loopsy_transfer_file,loopsy_context_set, etc.) so AI agents can drive remote machines, share state, and pass messages. - Persistent PTY sessions: Spawn long-running sessions on remote machines, poll them later from your laptop or phone, and tear them down when done.
- Shared key-value context store: Agents on different machines can read and write shared state, enabling multi-agent pipelines without direct coordination.
- Secure pairing: ECDH (P-256) key exchange with a 6-digit short authentication string for LAN peers; HMAC-signed pair tokens and SHA-256 hashed secrets for phone pairing.
- Per-session auto-approve: Opt in to skip confirmation prompts on a per-session basis; defaults off and requires macOS user password to enable.
- Cross-platform CLI: Works on macOS, Linux, and Windows; supports launchd, systemd, and Task Scheduler for auto-start on login.
