Grass vs Claude Code Remote Control: Which Should You Use?

Updated October 2026 — This refresh covers Anthropic's Cowork Dispatch, which launched March 2026 as the native first-party answer to remote Claude Code control from your phone.

Anthropic's Claude Cowork Dispatch and Grass both let you control AI coding agents from a phone — but they answer different versions of the problem. Dispatch is a remote control that drives Claude Desktop on your local machine from the Claude mobile app, requiring your Mac or Windows PC to stay awake and connected. Grass is an always-on cloud VM — it runs Claude Code, Codex, and Open Code on persistent infrastructure so your laptop can close and the agent keeps going. For developers evaluating options in October 2026: Dispatch is closed to new users as of September 16, 2026, which immediately narrows this comparison for most readers.

TL;DR

Dispatch (existing users only): Remote control your desktop. Claude-only, zero npm needed, requires laptop on. No longer open to new signups.

Grass: Always-on cloud VM. Agent-agnostic (Claude Code, Codex, Open Code). Laptop can sleep. BYOK. Free tier: 10 hours, no credit card.

Verdict: If your machine stays on and you already have Dispatch access, it's simpler for Claude-only tasks. If your machine ever sleeps, you run multiple agents, or you're evaluating today, use Grass.

What Changed in October 2026

Two things happened simultaneously that make this comparison non-obvious right now.

First, Dispatch closed to new users on September 16, 2026. Anthropic's help center states: "Dispatch isn't available to new users. If you already use Dispatch, you can keep using it for now." If you don't already have access, the comparison is effectively moot — Dispatch is not an option you can sign up for.

Second, Anthropic is migrating Cowork to cloud-first on October 6, 2026, removing the "Only on your computer" option. After that date, general Cowork tasks run on Anthropic's infrastructure with no laptop-on requirement. This migration triggered significant backlash in r/ClaudeAI — users describing it as a "blatant data grab" and noting "this is CC under the hood anyway... a move towards vendor lock-in." The practical effect: after October 6, Dispatch remains relevant only for tasks requiring local file access, local app control (computer use), or local connectors. General coding tasks against a remote repo? Cloud Cowork handles them without Dispatch.

What Is Claude Cowork Dispatch?

Dispatch is a feature of Claude Cowork — Anthropic's task-delegation product — that pairs your phone with Claude Desktop via a QR code scan. When you assign a task from the Claude mobile app, it routes to a Cowork session on your desktop. Coding tasks dispatch to Claude Code. The structural constraint is what you need to internalize first: Dispatch is not cloud compute. Anthropic's own mobile documentation is explicit: "Remote Control and Dispatch drive your own machine, so it needs to stay on with Claude Code or the Desktop app running."

The practical limitations are real. DataCamp's documented breakdown covers four: host awake requirement (desktop must be on, internet connected, Claude Desktop open); no push notifications on mobile; single thread only; no scheduled or recurring tasks from mobile. A dev.to review from March 2026 captured the core frustration: "Lid closed? Sleep mode? Network hiccup? Everything stops. If you want always-on availability, you're leaving a laptop open on your desk while you're on a train."

Dispatch is also Claude-only. It routes through Anthropic's infrastructure and requires a Pro or Max subscription ($20–$200/month). There is no path through Dispatch to Open Code, Codex, or any non-Anthropic agent.

What Is Grass?

Grass is a machine built for AI coding agents. It gives every developer an always-on cloud VM — powered by Daytona — with Claude Code, Codex, and Open Code pre-loaded, accessible from your laptop, your phone, or an automation. The architectural difference from Dispatch is compute: when you fire off a task from the Grass iOS app, that task runs on persistent cloud infrastructure. Your laptop state is irrelevant.

Grass has two surfaces. The cloud VM product at codeongrass.com runs agents on Daytona infrastructure — free tier is 10 hours, no credit card required. The local CLI (@grass-ai/ide, open-source MIT) runs agents on your own machine and connects your phone via QR code over WiFi. Setting up Claude Code on Daytona is a complete walkthrough if you want the cloud VM approach without Grass's managed layer.

BYOK (bring your own key) is a structural design choice, not a feature flag. Your Anthropic API key is configured in your environment and calls the API directly. Grass never sees it. For developers working on privacy-sensitive code or in organizations with strict data handling policies, this is a hard architectural difference from Dispatch.

Head-to-Head: Dispatch vs. Grass

Does Claude Cowork Dispatch Work with the Laptop Closed?

No — at least for local-file tasks, which is Dispatch's primary use case. The r/ClaudeCowork community documented this pattern from launch: "Cowork doesn't run in the cloud. The LLM is in the cloud but all the files it creates are on your computer. So yes your computer needs to be awake for Cowork to operate and respond." The workaround culture that emerged — buying Mac minis as dedicated always-on hosts, running Awayke to prevent sleep, setting up SSH tunnels — signals both that demand for always-on is real and that Dispatch's architecture doesn't satisfy it natively.

After October 6, 2026, Anthropic's cloud Cowork handles general tasks without the laptop-on requirement. But this is cloud Cowork, not Dispatch — it routes through Anthropic's infrastructure instead of your local machine. Dispatch specifically remains tied to local execution for the tasks it's still designed for.

Is Dispatch Claude-Only While Grass Is Agent-Agnostic?

Yes — and for developers running multiple agents, this is the most consequential structural difference. Dispatch routes through Cowork and Claude Desktop; there is no Dispatch path to Open Code, Codex, or any other agent. Grass is agent-agnostic by design: Claude Code, Codex, and Open Code all live as first-class citizens on the same cloud VM, with the same session model and permission forwarding. A developer on r/vibecoding who built a competing dispatch tool before Anthropic launched theirs summarized the architectural trade-off directly: "Anthropic's version: sandboxed VM, Mac must stay awake, single thread, Claude only. Ours: multi-agent, 18+ tools, all major CLIs, background service, BYOK, multi-channel."

For developers running parallel repos with different agents — Claude Code on one project, Open Code with GPT-4o on another — Grass handles all sessions from one surface. Dispatch has no answer for that workflow.

The BYOK Question: Who Sees Your API Key?

Dispatch routes through Anthropic's infrastructure — your Pro or Max subscription authenticates you and sessions flow through Anthropic's systems. That is the architecture Anthropic built, and for most users it is not a concern.

Grass uses BYOK. Your Anthropic or OpenAI API key is configured in your Grass cloud VM's environment and makes API calls directly. Grass infrastructure handles session routing but never stores your key. For developers working in organizations with strict data handling requirements or with code they won't route through third-party cloud infrastructure, this is a hard boundary. The API key security patterns for coding agents on a VPS cover the same model in depth: key in environment, scoped permissions, no third-party key storage.

The community backlash on the October 6 Cowork migration — "there's literally no reason local data needs to be uploaded to the cloud for Cowork to work with it" — reflects how seriously this audience takes data routing. Those users are now actively looking for Claude Code alternatives with local or BYOK execution, which is exactly the Grass value proposition.

Which Should You Use? Verdict by Scenario

Use Dispatch if: You already have access (closed to new users). You use only Claude Code and Cowork. Your desktop is reliably on during remote sessions. You want zero technical setup and don't need multi-agent support.

Use Grass if: Your laptop sleeps or travels with you. You run multiple agents (Open Code, Codex, Claude Code). You need BYOK with no third-party key storage. You're evaluating options today and don't have Dispatch access. You're on Linux and need full agent functionality. You want unattended overnight tasks.

Use Claude Code cloud sessions (Anthropic-managed) if: You want Anthropic-managed compute for Claude Code with laptop-off support, you're already on Pro or Max, and you don't need agent-agnostic infrastructure.

Use neither for general knowledge work: After October 6, cloud Cowork handles document and research tasks natively — Dispatch and Grass both solve coding-agent-specific problems that general Cowork doesn't address.

The landscape in October 2026 is more fragmented than it appears. The full comparison of mobile agent control tools tracks seven active options as of September 30, 2026; Grass is the only one with both a native iOS App Store presence and a cloud VM where sessions survive laptop power-off.

Frequently Asked Questions

Does Claude Cowork Dispatch work with the laptop closed?
No. Dispatch requires your desktop to be on, awake, and running Claude Desktop for the duration of any task. If your laptop closes or enters sleep mode, the session stops. After October 6, 2026, general Cowork tasks run in the cloud without this constraint — but Dispatch specifically (for local file and computer use tasks) still requires the laptop on.

Is Claude Cowork Dispatch available to new users in October 2026?
No. Anthropic closed Dispatch to new signups on September 16, 2026. The help center states: "Dispatch isn't available to new users. If you already use Dispatch, you can keep using it for now." New users evaluating mobile agent control cannot enroll in Dispatch.

What is the difference between Dispatch and Grass for mobile agent control?
Dispatch is a remote control that drives Claude Desktop on your local machine — your laptop must stay on and Claude Desktop must be open. Grass is compute — it runs agents on an always-on cloud VM so your machine state is irrelevant. Dispatch is Claude-only and requires an Anthropic subscription. Grass is agent-agnostic (Claude Code + Open Code), uses BYOK, and has a free 10-hour tier with no credit card.

Does Grass work with Claude Code, Codex, and Open Code?
Grass runs Claude Code, Codex, and Open Code as equal first-class citizens today. You choose the agent per session from the iOS app. All sessions run on the same always-on cloud VM with the same permission forwarding and diff viewer.

Can I use Grass without a Claude Max subscription?
Yes. Grass uses BYOK — you bring your own Anthropic API key and pay API costs directly. You don't need a Pro or Max subscription. The free tier provides 10 hours of cloud VM time with no credit card required.

Getting Started

If you're evaluating now and don't have Dispatch access, your practical choice is between Grass and Claude Code's native cloud sessions. Grass's free 10-hour tier at codeongrass.com takes about 5 minutes to set up — install the CLI, connect the iOS app, pick an agent, and fire off a task with your laptop closed.
