For Claude Code & OpenAI Codex on macOS

AI coding agents in your pocket.

Pair your iPhone to your Mac with a single QR scan, then drive every Claude Code or Codex session from anywhere. Read transcripts. Send prompts. Stop runs. Pick which agent answers each new session. Keep shipping without sitting in front of the keyboard.

iOS 17 + macOS 14 · $0.99 · the Mac helper is free

Built for the way you actually ship code.

Every session, in one list.

CLI sessions and Claude for Mac Co-work sessions side by side — titles, models, last-activity. The same list as your desktop.

Live transcripts, beautifully rendered.

Markdown with tables, nested lists, and syntax-highlighted code blocks. Responses stream in as Claude writes them.

Prompt, steer, stop.

Send a new prompt, pick Opus / Sonnet / Haiku, fork to try an alternative, stop a run mid-flight. Your Mac does the work.

Push when it matters.

A tap on the shoulder when a turn completes or errors. Short summaries only — nothing sensitive ever leaves your Mac.

End-to-end encrypted. No cloud.

X25519 pairing, ChaCha20-Poly1305 payloads via Apple CryptoKit. Direct iPhone → your Mac. No relay server, no telemetry.

VPN-native, not VPN-locked.

Works on LAN out of the box. Tailscale, WireGuard, ZeroTier, Cloudflare Tunnel, plain static IPs — all fine.

“The phone doesn't replace your keyboard. It just makes sure you don't have to be sitting in front of it.”

Compatible with your Claude or ChatGPT plan

It’s just your CLI — on your Mac, in your hand.

RelayKit doesn’t replace your coding agent. It doesn’t call Anthropic’s or OpenAI’s API. It doesn’t hold your credentials. The official Claude Code and/or Codex CLI runs on your own Mac, signed in with your own account — same as if you opened Terminal and typed claude or codex. RelayKit is a remote control for that local session. Think of it as an IDE extension that happens to live in your pocket.

  • Your Mac authenticates to Anthropic and/or OpenAI. RelayKit never sees or proxies your OAuth tokens.
  • No RelayKit-operated server sits between your iPhone and your Mac. The phone talks to your Mac directly.
  • Drives interactive Claude Code and Codex sessions — not headless Agent SDK / claude -p / codex exec automation.
  • Usage counts against your normal Claude Pro/Max or ChatGPT plan limits, exactly like running the CLIs yourself.
  • Pick a default backend in Settings → Backends. Run both at once if you want; each session shows a chip so you always know which agent is answering.

RelayKit is independent software from Schalliol Automation. Not affiliated with Anthropic or OpenAI.

Privacy is a feature, not a policy.

  • No relay server. Traffic goes iPhone → your Mac and nowhere else.
  • No analytics. No trackers. No third-party SDKs. Nothing to opt out of.
  • Apple CryptoKit end-to-end: X25519 → HKDF-SHA256 → ChaCha20-Poly1305.
  • Keys live in the Keychain on both devices. One-tap unpair wipes them.
