Doom Coder vs Supermux

Doom Coder sends a notification to your iPhone and iPad the moment your AI coding agents finish, fail, or stop to ask for approval — so you can start a long run, walk away, and trust your phone to call you back. It pairs with the free Doom Coder app for Mac, which watches your agents and keeps your Mac awake while they work. When an agent needs you, the alert reaches your phone in seconds. WORKS WITH YOUR AGENTS Doom Coder understands the events from Claude Code, Cursor, VS Code Copilot, Copilot CLI, Windsurf, Codex CLI, and opencode. You choose exactly which events alert you — completed, failed, waiting for approval, waiting for input — and mute the rest. USEFUL THE SECOND YOU OPEN IT No account. No sign-in. No Mac required to get started. • Prompts — A prompt refiner, not a chatbot. Type a rough request and get back a clean, structured prompt you can paste straight into your agent. Keep refining over follow-up turns, and pull from a built-in library of developer prompts grouped by Refactor, Tests, Debug, Review, Explain, Git, Docs, and Scaffold. • Notes — On-device notes with checklists, reminders, pinning, and search. Turn any note into a prompt with one tap. • Dashboard — Once you pair a Mac, see every agent's live status and drive the Mac's keep-awake controls from your phone. PRIVATE BY DESIGN No servers. No analytics. No tracking. Everything you write stays on your device. When you pair a Mac, sync happens only through your own private iCloud account using Apple CloudKit — your data is never visible to us or anyone else. ON-DEVICE OR BRING YOUR OWN KEY The prompt refiner runs on Apple Intelligence entirely on your device, so nothing leaves your phone. Prefer your own model? Add an OpenAI or Anthropic API key — it is stored only in your device's Keychain, and only the text you choose to enhance is ever sent. Enhancing is always optional. BUILT FOR iOS 26 AND iPadOS 26 A native interface with the system Liquid Glass design, a macOS-style sidebar on iPad, and time-sensitive notifications that reach you even through Focus. Doom Coder is open source. Source, documentation, and support: github.com/katipally/Doom-Coder

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.
