What is Grass?

Grass is a mobile-first tool that lets you dispatch tasks to a persistent virtual machine (GrassVM) from your iPhone, close your laptop, and return to completed results. It solves the problem of agent sessions dying when your laptop sleeps, loses connection, or hits a permission wall. Built for engineers who run agents, not just write code, Grass keeps your agent running even when you're not at your desk. It works with Claude Code and Opencode, and sessions survive sleep with notifications in under two seconds—no SSH required.

Application scenarios

  • Overnight builds

    Fire a build task before bed, close your laptop, and wake up to finished results without babysitting the terminal.

  • Remote approvals

    Approve or reject permission requests from your phone while away from your desk, even at 2am.

  • Multi-machine workflow

    Switch between GrassVM, your Mac, and your server in one tap without losing context.

  • On-the-go debugging

    Review diffs and redirect agents from anywhere, like a beach in Goa, while the agent keeps running.

  • Uninterrupted agent sessions

    Keep sessions alive during meetings, WiFi drops, or laptop closures so the agent never stalls.

  • Mobile-first development

    Start 68% of sessions on iPhone and run them to completion 3× more often than before.

Core Features

  • Persistent GrassVM

    Your agent runs on a machine that doesn't sleep—close your laptop and the session stays alive until work is done.

  • Mobile permission approvals

    Every permission request surfaces as a push notification on your phone; tap to approve or reject instantly.

  • Diff review on phone

    View added, modified, deleted, and renamed files per-line, organized by repo and navigable—not a terminal wall of text.

  • Multi-machine switching

    Switch between GrassVM, your Mac, and your server in one tap without losing session context.

  • Fast notifications

    Notifications arrive in under two seconds, keeping you informed without SSH.

  • Claude Code and Opencode integration

    Works seamlessly with popular agent tools so you can dispatch tasks from your iPhone.

  • Session survival

    Sessions outlast your attention span—fire a task, close your laptop, walk away, and come back to results.

  • No SSH required

    No need to SSH in to check if a session is still running; everything is managed through the app.

Target users

Senior engineers, developers, and technical leads who run long-duration agents, build overnight, or need to approve code changes while away from their desk. It's especially useful for remote workers, frequent travelers, and anyone who wants to stop babysitting terminals.
