Arc0

Arc0 is a mobile command center for AI coding agents that bridges your terminal to your phone. It creates a secure tunnel between coding agents like Claude Code, Codex, and Gemini CLI running on your laptop and the Arc0 app, letting you monitor and interact with sessions from anywhere. The tool enables developers to stay productive without being tied to their desk by providing real-time control over agent workflows.

• Real-time Session Monitoring - Watch coding sessions unfold in real-time, see which files agents are working on, what commands they're running, and track progress to catch issues early.

• Interactive Prompting - Send prompts and provide guidance to your agents from your phone, adjust scope, clarify requirements, or pivot direction mid-task without opening your laptop.

• Plan Approval - Review your agent's implementation plans before coding begins, approve approaches, request changes, or redirect entirely from mobile.

• Mobile-Optimized Diff Review - Inspect code changes with a mobile-friendly viewer, review diffs, manage worktrees, and approve changes before they get committed.

• Artifact Browsing - Browse tasks, plans, and files your agents create as they work, keeping full visibility into agent outputs.

• Push Notifications - Receive alerts when agents need input, finish tasks, or hit blockers so you never miss critical moments.

• End-to-End Encryption - All code and conversations stay private with AES-256-GCM encryption, ensuring only you can decrypt your data.

• Self-Hostable Architecture - Run Arc0 CLI on your machine with zero cloud dependency, use the provided tunnel or bring your own infrastructure.

• Open Source - Fully auditable under MIT license, inspect every line of code on GitHub and contribute improvements back.

To get started, install the Arc0 CLI with a single command (curl -fsSL arc0.ai/install.sh | bash), run arc0 start to launch the daemon and create a secure tunnel, then connect your phone by visiting the connection link or scanning the QR code. The setup takes approximately 15 seconds and requires no signup. Arc0 works seamlessly via tmux without requiring any modifications to your existing CLI tools or workflows.
