Styrby

One app to control all your AI coding agents from your phone.

Control Claude Code, Codex, Gemini CLI, OpenCode, and Aider — all from a single mobile app. End-to-end encrypted. Your code never leaves your machine.

Why Styrby?

• Multi-agent — 5 AI agents, one interface. No vendor lock-in.
• E2E encrypted — XSalsa20-Poly1305 encryption with per-session keys. We never see your code.
• Offline resilient — Commands queue when you're offline and sync automatically. Your laptop can sleep.
• Cost tracking — Real-time token usage, budget alerts, and cross-agent cost comparison.
• Push notifications — Know when sessions complete, permissions need approval, or budgets are hit.

Install

npm install -g styrby

How It Works

Styrby is a relay layer — it doesn't do AI coding itself. Instead:

1. You spawn an agent (Claude Code, Codex, etc.) on your machine
2. Styrby captures stdin/stdout and encrypts messages end-to-end
3. Your phone connects via Supabase Realtime
4. You type on your phone → agent executes on your machine
5. Results are encrypted before leaving your machine → decrypted only on your phone

Security

• End-to-end encryption — TweetNaCl (XSalsa20-Poly1305) with HMAC-SHA512 key derivation
• Per-session keys — Each session generates unique keys bound to user + machine + session
• Zero-knowledge relay — Styrby servers forward ciphertext only, never plaintext
• No third-party messaging — Unlike solutions routing through Telegram or Discord, your data stays on your infrastructure

Requirements

• Node.js 20+
• One of the supported AI agents installed
• Styrby mobile app (iOS/Android) or web dashboard
