Pi Relay is a companion iPhone app for the Pi coding agent. It lets you connect securely to your own Pi remote-control server, browse active projects and sessions, and continue conversations from your phone. Pairing is simple: install the Pi remote-control extension on the machine running Pi, open the pairing QR code, and scan it with Pi Relay. Once paired, you can switch between remotes, view project sessions, read conversation history, send new prompts, abort running work, and request context compaction with /compact. Pi Relay is designed for users who already run Pi on their own computer or development environment and want a lightweight mobile companion for monitoring and continuing work away from the desktop. Key features: - QR-code pairing with your Pi remote-control server - Remote list with quick switching and unpairing - Project and session browsing - Conversation view with selectable and copyable messages - Runtime status and context usage display - Prompt sending, abort support, and /compact support - Live session updates while the app is active Pi Relay requires a running Pi remote-control extension/server. The extension is available at: https://github.com/zerray/pi-remote-control

Your coding agents shouldn't stop just because you left your desk. Shahi turns the AI coding agents running on your own computer into a conversation on your phone. Read what they're doing like a chat, answer their questions with one tap, and start new work from anywhere, while your computer keeps going. WHAT YOU CAN DO • See every agent at a glance: which ones are working, which are done, and which are waiting on you. • Answer permission prompts and questions in one tap. Before anything is pressed, the answer is checked against the agent's live screen. • Read conversations as clean messages, including tool activity, instead of a terminal squeezed onto a small screen. • Reply, attach photos and files, and keep the conversation going. • Start a new agent in any project, with the permission mode you choose. • Open the real terminal whenever you need it. • Preview files and PDFs from your computer. WORKS WITH YOUR SETUP Shahi connects to herdr, the open-source terminal workspace for coding agents, on your own Mac or Linux computer. It works with Claude Code, Codex, Cursor and the other agents herdr runs. Setup takes two commands and one QR scan. PRIVATE BY DESIGN • End-to-end encrypted. The relay that connects your phone to your computer can't read your conversations. • Prefer no third party at all? Connect over your own SSH instead. • Your code and conversations stay on your computer. There's no account to create. • Open source, under the MIT license. WHAT YOU NEED A Mac or Linux computer running herdr with the free Shahi plugin. Get started at getshahi.dev.
