Codync vs Grass

Message your coding agents like teammates. Codync turns the coding agents on your computer — Claude Code, Codex, Cursor, Pi, OpenCode, Grok Build, Gemini, GitHub Copilot and dozens more — into persistent bots you delegate to from your iPhone. Pick who, say what, put the phone away. BOTS, NOT SESSIONS Give each bot a name, a character, standing instructions, an agent and a project folder. Each bot is one ongoing conversation, so there's no hunting for the right session or setting up an environment every time — just open the chat and type. APPROVE FROM ANYWHERE When an agent wants to run a command or change files, an approval card arrives in the chat: Allow once, Always allow or Deny. You get a notification only when a bot needs you or finishes. A CALM CHAT The conversation shows your messages and each final reply. Every command, file change, plan and thought is one tap away in Full conversation. While a bot works, you see what it's doing right now. USAGE AT A GLANCE See your Claude and Codex subscription limits in the app, in widgets and on the Lock Screen. Follow a working bot in a Live Activity and the Dynamic Island. YOUR COMPUTER, YOUR CODE Agents run on your Mac or Linux machine with your own logins. Away from home, the free built-in relay connects your phone end-to-end encrypted, so it only ever forwards ciphertext; on the same Wi-Fi or Tailscale the phone connects directly. Your code and conversations stay on your computer. GET STARTED Install Codync on your Mac (brew install --cask leepokai/codync/codync) or the host on Linux, then scan the pairing code.

Meet Grass. Your agents work. You check in. Fire a task. Pocket your phone. Come back to progress. Grass RUNS Tasks on Grass Computer or your own machine - while your laptop is closed, while you're in a meeting, or while you're away from your desk. No terminal to watch. No session to babysit. Grass MOVES Send a coding session to Grass and keep the thread moving on a remote instance — conversation, context, and all. Your phone buzzes when it's live. Grass ALERTS The moment your agent needs a decision or finishes the job. You don't push for status. Status finds you. Permission needed? Approve from your pocket. Grass CLEARS Every permission prompt from every thread in one tab. Read the diff. Yes or no. Keep multiple threads running in ask-mode without watching all of them. Grass STARTS A new thread in two taps. Quick chat button → bottom sheet → task running. No app switching. No losing your place. The idea fires — the experiment actually runs. Grass SHOWS Which thread is which. Running, completed, waiting — all visible on the home screen the moment you open the app. Switch machines with one tap. Name them whatever you want. Your harness. Your code. Our compute. Designed for AI coding agent workflows, including supported integrations with Claude Code and OpenCode.
