PlayGen vs Supermux

Now with AI test generation! Describe what to test and Playback builds your test suite automatically — no code, no setup, just results.

Supermux is a native remote client for the Supermux broker you run on your own computer. Pair your iPhone or iPad to your machine and drive your AI coding agents — Claude Code, Codex, Cursor, and OpenCode — from anywhere. It works like an SSH or remote-terminal client: every command and agent action runs on your own computer, and your phone sends input and shows the results. Nothing runs on the device, and your code and credentials never leave your machine. WHAT YOU CAN DO - Watch and steer agent sessions in real time: approve steps, redirect, or jump in - Run multiple sessions at once and switch between them - Use the built-in terminal and code editor on the go - Reply by voice: speech is transcribed on-device into editable text - Start new sessions, pick a project, and create or clone repos - Pair in seconds by scanning the QR code your broker prints HOW IT WORKS Supermux connects to a broker that you host on your own computer, over your local network or a private mesh like Tailscale. You bring your own machine and your own agent subscriptions — there is nothing to buy in the app. Requires a running Supermux broker. Learn how to set one up at supermux.dev.
