Grass

What it does

Grass provides a persistent virtual machine (GrassVM) for AI coding agents like Claude Code and OpenCode. You dispatch a task from your iPhone, the agent runs on the VM, and you can close the app—the session continues. You monitor progress, review diffs, and approve permission requests from your phone via push notifications. No SSH or terminal babysitting required.

Who it is for

Grass is built for engineers who run AI coding agents and need them to work beyond their local machine. It's for developers who want to start a task from their phone, walk away, and come back to results. The target user is someone who uses agentic coding tools but is frustrated by sessions dying when their laptop sleeps or loses connection.

Why it matters

Traditional agent workflows tie the session to your laptop: close the lid, lose WiFi, or step away, and the agent stops. Grass decouples the agent from your machine, letting it run on a cloud VM that stays alive. This means you can ship overnight, approve file writes from anywhere, and never lose context. The site claims 3× more sessions run to completion after using Grass.

Launch signal

Grass launched on iOS with a free tier offering 10 hours of VM time, no credit card required. The app has a 4.7/5 rating on the App Store. An Android waitlist is open. The product is live and being used by engineers like Arjun Mehta, who says: "I approved a file write from a beach in Goa. The PR was merged before I even finished my coffee."

Brand and naming

The name "Grass" suggests something that grows persistently and doesn't sleep—matching the product's promise of a VM that's always on. The tagline "Your agent runs. Even when you don't." reinforces the value of unattended operation. The brand positions itself as infrastructure for the agent era, not just another coding tool.
