Murmur BLE Shell vs TTY.Build

murmur turns your phone into a remote control for a Raspberry Pi — no Wi-Fi, no network setup, no port forwarding. Just Bluetooth Low Energy (BLE), directly between your phone and the Pi. HOW IT WORKS Install the open-source murmur daemon on any Raspberry Pi running Linux, pair your phone with it over Bluetooth, and you get: • Shell mode — a real interactive terminal on the Pi, right from your phone. • Agent mode — describe what you want in plain English ("what's eating my disk space?", "set up a static IP") and an AI agent plans and runs the shell commands for you, showing every command and its output as it goes. BRING YOUR OWN API KEY Agent mode is powered by your own Anthropic Claude, OpenAI, or Google Gemini API key — entered once in Settings, stored only in your phone's secure keychain. murmur has no backend server and no account system. The only network calls it makes are the LLM requests you trigger yourself, using your own key. WORKS OFFLINE ON THE PI SIDE The Raspberry Pi never needs an internet connection. It just needs Bluetooth and the murmur daemon running. Good for headless boxes, home labs, and devices you'd rather not put on a network at all. PRIVACY BY DESIGN Everything murmur stores — the Bluetooth pairing key, your API key, an optional per-device sudo password, and saved agent conversations — stays on your phone in the OS-level secure store. One tap in Settings wipes it all. OPEN SOURCE Both the daemon and the app are open source: github.com/nekonihq/murmur

TTY.Build keeps your coding agents and terminals within reach from iPhone and Apple Watch. See every agent in one Home view. Session names, latest assistant output, and live status make it clear what is running, what finished, and what needs you. TTY.Build surfaces attention through Live Activities and Dynamic Island, so you can stay informed without a stream of ordinary notifications. When an agent needs intervention, open the same computer terminal and take over from iPhone. TTY.Build also works as a complete remote terminal even when you do not use coding agents. • Monitor Claude Code, Codex, Copilot CLI, Grok, Kimi Code, Kiro, OpenCode, Oh My Pi, Pi, and Hermes • Session titles, latest agent output, and live running, waiting, error, and finished states • Live Activity, Dynamic Island, Home, and Apple Watch status • Full end-to-end encrypted remote terminal sessions • Multiple terminals across multiple computers • Touch-friendly terminal toolbar and extended keyboard • One-time 8-digit pairing—no ports to expose and no VPN to configure • Native macOS menu bar companion with automatic updates Privacy is part of the architecture. The TTY.Build service relays encrypted terminal and agent data; it never stores terminal input, output, titles, working directories, or pairing secrets. A Mac running the TTY.Build desktop app is required. Agent monitoring support depends on each agent's hook capabilities.
