CosmoRemote: Mac Build & Test

Your Mac keeps working while you are away. Claude Code, Codex and Cursor run on it; the build, the log and the running app stream to your phone. Read the result, tap through the app, send the next prompt.

SEE THE BUILD, NOT JUST THE DIFF
Pick an iOS, Android or web project and a simulator or emulator from your phone. Your Mac builds, installs and launches the app, and the screen streams to you live. Tap, swipe and type on it; every touch goes straight to the simulator.

KEEP THE CONVERSATION GOING
Claude Code, Codex, Cursor and a full terminal stream token by token. Open a session you started at your desk and the whole transcript is already there. Send the next prompt from the couch, the train or the coffee line.

A FAILED BUILD IS A READABLE LOG
Build output, a web preview of your local dev server and an API client for the backend on your Mac, all next to the screen. Find the problem, then hand it to the agent in one tap.

EVERY MAC, ONE BOARD
The Fleet dashboard shows every session on every Mac, filtered by CLI, host and status: running, idle, needs you, errored. A push arrives when a turn finishes or a session is waiting on you.

TWO COMMANDS AND A SCAN
1. brew install matheusjkweber/tap/cosmoremote (or npm install -g cosmoremote)
2. cosmoremote start, inside your project
3. Scan the QR code in the app, or type the 4-digit code
On your home network that is all. Away from home, an encrypted relay carries the traffic between your phone and your Mac.
