WhatCode

You start a long-running task, put your phone down, and WhatCode taps you on the shoulder when it's done.

WhatCode is an iOS app that brings OpenCode to your iPhone. It connects to the OpenCode server running on your machine and lets you browse projects, read and continue coding sessions, and get a push notification the moment an agent finishes its work.

Features​

Project browser - all your OpenCode projects in one place, sorted by most recent activity. Always know which session needs your attention next.

Session view - read the full conversation history of any session, see every file the agent touched, and continue the conversation without touching your computer.

Push notifications - get notified the moment something happens:

• An agent finishes a turn and goes idle
• An agent hits an error
• An agent needs your permission to proceed

Multiple machines - stay connected to every machine at once. Whether you run OpenCode on a work laptop, a personal desktop, or both, they all show up in one place.

Tailscale support - start the daemon with --tailscale and connect securely from anywhere, no VPN setup required.

Setup​

See Getting Started for the full connection walkthrough. In short:

1. Run npx @whatcode-ai/whatcode on your machine.
2. Scan the QR code with the app.
3. Done.

Adding accounts manually​

If you can't scan the QR code, tap Continue without QR during setup and enter:

• Server URL - the local IP printed in your terminal (e.g. http://192.168.1.10:8192) or your Tailscale HTTPS URL.
• Password - optional, only if you started the daemon with a password (see Daemon).

Notifications​

Notifications are delivered via APNs (Apple Push Notification service) through a relay server. The daemon on your machine listens to the OpenCode event stream, detects when a session goes idle or errors, and sends a push through the relay to your device.

No polling. No battery drain. You get the notification within seconds of the agent finishing.
