Let your agent work. We'll page you when it stops.
The remote control for your coding agent — Claude Code,
Codex, Grok, and any terminal CLI.
When it pauses for input, your phone pings: tap, approve, keep moving.
Private beta. MobileCoder is open to just a handful of testers right now.
DM me on X @fuat_kerkinni
and I'll send you a free copy to test.
# Your agent runs for 20 min. You're stuck for 20 min.
Your coding agent is autonomous — until it pauses for input.
Without a leash, you're parked at your desk just in case.

# How the leash works
A tiny Mac utility watches your agent. Your iPhone is its remote.
Everything between them is encrypted.
[1] push when it pauses
Your Mac watches your agent in real time. The moment it stops for input, your iPhone gets a push — on cellular, abroad, or with your laptop closed across town.
[2] tap to respond
Read the agent's question. Type back, or hit numbered keys 1–5 for multiple-choice prompts. The UI is tuned for thumb-speed.
[3] mac keeps running
Your session stays alive at your desk while you're gone. Walk back, pick up where you left off — no reconnect, no replay, no lost context.

You can SSH to your Mac from your phone. Here's why we built this instead.

# Install the Mac companion
MobileCoder needs a small Mac utility (the wrapper) plus the iPhone app.
The wrapper is open-source, notarized by Apple, and runs only while
you're using your CLI — no daemon, no menu-bar agent.
[1] download
macOS 12+, Apple Silicon & Intel, ~55 MB. Signed + notarized.
Every message between your iPhone and Mac is end-to-end encrypted with
a key derived during pairing. Our relay forwards encrypted bytes —
it can't read your prompts, your code, or the agent's responses.
We store no messages. We run no analytics on your sessions. Your account
with Anthropic, OpenAI, xAI, or whichever provider you use stays yours —
MobileCoder never touches your API keys.
One app for Claude Code, Codex, Grok, and any terminal coding agent.

# FAQ
What if my Mac sleeps while I'm away?
Plug your Mac into power and disable display-sleep (or use Amphetamine/Caffeinate).
The agent process itself keeps running as long as the Mac is awake. MobileCoder
doesn't require lid-open mode — clamshell with external power works fine.
Will this work over cellular when I'm traveling?
Yes — that's the whole point. MobileCoder uses a Cloudflare tunnel from your Mac
to a global edge, so your iPhone reaches your Mac from any internet connection.
Do I need to keep my Mac running?
Yes — your Mac is where the agent actually runs. MobileCoder mirrors that session;
it doesn't replace it. Plug your Mac into power, disable display-sleep, and
you're set.
What if I miss a push notification?
The session waits. The agent doesn't time out on its own — it stays paused
until you respond, whether that's two minutes or two hours later. Open the
iPhone app any time to see what's pending.
Is my code visible to MobileCoder's servers?
No. Every message between your iPhone and your Mac is end-to-end encrypted
with a key derived during pairing (X25519 ↔ ChaCha20-Poly1305). The relay
sees encrypted bytes only — never plaintext.
Read the full policy.
How is this different from SSH-ing to my Mac from my phone?
SSH gives you a raw terminal — no voice, no push, no parsing of agent prompts,
no tap-to-approve. MobileCoder is built around the coding-agent interaction loop,
not generic remote shell access.
Do I need a separate AI account?
Yes. MobileCoder is the remote-control layer; the actual agent runs on
your Mac under your account with the provider —
Anthropic (Claude Code), OpenAI (Codex), xAI (Grok), and so on.
Usage and limits are between you and that provider.
What happens after the 7-day free trial?
Apple charges your Apple ID $9.99/month. Cancel any time in iOS Settings →
Apple ID → Subscriptions → MobileCoder. No charge if you cancel before the trial ends.
