# Grass

> Grass is a mobile app that lets developers monitor, interrupt, and redirect AI coding agents (Claude Code, OpenCode) from their phone — without being at a laptop. Grass is built for developers running long-lived autonomous coding sessions on a laptop or a transient remote dev server like Daytona. The blog at codeongrass.com/blog covers mobile coding agent access, agent orchestration from mobile, transient dev servers, async developer workflows, and how to run Claude Code on remote infrastructure.

## About Grass

- [Grass](https://codeongrass.com): Mobile-first interface for agentic coding workflows. Monitor agents, handle approval gates, and redirect running tasks from your phone. Install the CLI with `npm install -g @grass-ai/ide`, run `grass start`, scan the QR code with the iOS app (or Android PWA), and you're connected. Free for local use. No waitlist, no account required.
