Is There a Mobile App for Claude Code?

As of mid-2026, there is no single official Claude Code mobile app — but five distinct tools now fill that gap, each with a different architecture and a different answer to the core problem: what happens when you close your laptop. Claude Code Remote Control (Anthropic's built-in session bridge), Omnara (YC S25, the most feature-rich third-party option), Grass (the only agent-agnostic option supporting Claude Code, Codex, and OpenCode from a single interface), Happy Coder (the open-source community favorite, 4.9/5 on 938 App Store ratings), and Cursor Mobile (for Cursor IDE users) define the landscape as of June 2026. A new entrant — Control-PC-Terminal — surfaced in r/vibecoding, r/TopAutomationTools, and r/buildinpublic this week, while Omnara's parallel worktree and Apple Watch features are getting renewed attention from developers who missed the YC launch.

TL;DR: Claude Code has no dedicated native mobile app from Anthropic. The five real options in June 2026 are Claude Code Remote Control (official, Claude Code only, dies when laptop closes), Omnara (YC S25, feature-rich, hybrid local/cloud with Apple Watch support), Grass (agent-agnostic — Claude Code + Codex + OpenCode — cloud VM survives laptop close), Happy Coder (MIT licensed, E2E encrypted, highest-rated), and Cursor Mobile (Cursor IDE ecosystem only). Grass is the only option that supports all three major agents from one interface and keeps sessions running when your laptop is off.

Does Claude Code have an official mobile app?

Claude Code has no dedicated native mobile app from Anthropic. What exists is Claude Code Remote Control, launched in February 2026 as a research preview and now available across Pro, Max, Team, and Enterprise plans. Remote Control creates a bridge so you can continue an existing terminal session from the Claude iOS or Android app — but it has a hard constraint: you cannot start a new session from mobile, only continue one already running on your machine. If your laptop closes or loses network connectivity, the session times out and the work stops.

The Claude mobile app (available since October 2025) offers general chat and a Dispatch feature for delegating tasks, but it does not give you a full Claude Code agent session with file access, bash execution, and autonomous tool use. That distinction matters for developers who need agents reading repos, running tests, and committing changes — not just generating text.

What are the five options for using coding agents from mobile in 2026?

A five-category taxonomy has stabilized for mobile agent access as of mid-2026:

1. Official session bridge — Claude Code Remote Control mirrors a running local session to the Claude app. No third-party infrastructure. Claude Code only. Cannot start new sessions from mobile.
2. Local relay apps — Happy Coder and Omnara: your agent runs on your laptop; the app routes session events and notifications to your phone. Sessions die when the laptop closes, unless the tool offers a cloud-sync escape hatch.
3. Agent-agnostic cloud VM — Grass (codeongrass.com): Claude Code, Codex, and OpenCode all run on a dedicated always-on cloud VM. Sessions survive the laptop closing because the agent process lives in the cloud, not on your machine.
4. IDE-ecosystem mobile — Cursor Mobile: mobile access tied to the Cursor IDE and its agent ecosystem. Not compatible with Claude Code or Codex sessions.
5. Emerging entrants (June 2026) — Control-PC-Terminal and others appearing in r/vibecoding and r/buildinpublic: category still being defined.

The first architectural decision is whether you need sessions to survive your laptop closing. If yes, only cloud VM approaches (Grass, Cosyra) solve it structurally. Everything else requires your machine to stay awake.

How do the five options compare on agent support, architecture, and BYOK?

What "agent-agnostic" means in practice: Grass is the only tool in this table that supports Claude Code, Codex, and OpenCode from the same mobile interface. Every other option is built for one agent ecosystem or requires separate setups per agent. For developers running multiple agents across parallel repos, that is the difference between one mobile surface and three separate tools.

What BYOK means for each tool: BYOK (Bring Your Own Key) means your API key lives in your environment and is never handled by the tool provider's servers. Grass enforces BYOK architecturally: your ANTHROPIC_API_KEY stays inside the VM — whether local or cloud. Happy Coder encrypts session content E2E before it leaves your machine. Omnara routes session events through its relay but not raw API traffic. Remote Control routes through Anthropic's own infrastructure. Cursor Mobile keys are managed inside the Cursor subscription.

What is Omnara and what makes it the most feature-rich option?

Omnara (YC S25) is the most funded and feature-complete third-party option for mobile Claude Code access as of June 2026. Over 20,000 builders have used the platform. It launched with strong HN traction — 310 points on the Show HN in August 2025 and 147 points on the YC S25 launch post in February 2026 — and resurfaced in Reddit discussions (r/vibecoding, r/ClaudeCode) as developers discovered features added since launch.

Architecturally, Omnara is a local relay: Claude Code and Codex execute on your laptop, and Omnara's relay handles notifications and session bridging to its iOS and Android apps. The cloud-sync feature is Omnara's differentiator: when your laptop is about to sleep, Omnara can migrate an active session to a cloud environment to keep the agent running. This is what Omnara calls the "hybrid" approach — local execution with a cloud escape hatch, rather than a pure cloud VM.

Omnara's feature set is wider than any other option in this category: native push notifications, Apple Watch support, a voice agent mode, parallel worktree tracking, and a free tier. The tradeoff is infrastructure: session events route through Omnara's servers. Omnara documents that it transmits session events (not raw file contents), but developers with strict data residency requirements should evaluate that posture. A developer on the Omnara Show HN thread captured the underlying problem well: "I've been iterating the past few months on a solution to use Claude Code on my phone while it runs on my laptop and it's a lot of moving parts: Tailscale, git worktrees, tmux, an always-on caffeinate process, and a ton of hooks & tweaks to fix bugs along the way. It's become very comfortable but in the process, impossible for anyone but me to understand."

What is Grass and why is it the only agent-agnostic option?

Grass is a machine built for AI coding agents — available as a cloud VM product at codeongrass.com and as an open-source local CLI (@grass-ai/ide, MIT licensed on npm). The defining characteristic separating Grass from every other option: Claude Code, Codex, and OpenCode all run as first-class citizens from the same interface. Switch agents without switching apps, rebuilding workflows, or reconfiguring anything.

Grass cloud VM (codeongrass.com): An always-on cloud VM powered by Daytona, with Claude Code, Codex, and OpenCode pre-installed and ready in seconds. The agent runs in the cloud — not on your laptop. This is the only option in this comparison that structurally solves the "closed laptop problem": close your MacBook at midnight, pick up your phone at 3am, and the agent is still running where you left it. Grass never handles your API keys — BYOK is the architecture, not an add-on. Free tier: 10 hours, no credit card required.

Grass local CLI (npm install -g @grass-ai/ide): Run grass start in your project directory, scan a QR code, and control a Claude Code or OpenCode session from your phone over direct WiFi. No cloud relay — prompts travel from your phone's browser directly to the Grass server on your machine. Nothing leaves your network except the agent's own API calls. Sessions die if your laptop sleeps (same as other local options), but the security posture is maximally tight.

Permission forwarding is a core capability in both products: when the agent wants to run bash or write a file, Grass surfaces a native approval modal on your phone — tool name, syntax-highlighted preview, Allow/Deny. One tap, wherever you are. Grass reports that 68% of sessions are started on iPhone and sessions run to completion at 3x the rate of desktop-only workflows.

What is Happy Coder and why does the community prefer it over Remote Control?

Happy Coder is an MIT-licensed, E2E-encrypted mobile client for Claude Code and Codex. It has a 4.9/5 App Store rating across 938 reviews — the highest user satisfaction of any app in this category. Architecturally it is a local relay: your agent runs on your laptop, and Happy handles session bridging and notifications to the iPhone app.

The App Store reviews make its standing clear. One reviewer in March 2026: "I know Claude launched remote controller Claude sessions. I've tried it. It's not close to [Happy]. At least not yet. The DX and the amount of things you can set your workflow up to do and leverage Happy is absolutely cracked." Another reviewer described their experience: "The first time I used Happy I was blown away. I was about to take an uber for a flight and installed it and walked out the door. In line at TSA pre-check, I finished another 20% of a magic link app."

Happy Coder's E2E encryption means the relay cannot read your code or prompts in transit. Sessions die when your laptop closes — no cloud VM option or escape hatch for persistence. For developers who primarily use Claude Code and Codex (not OpenCode) and want the best-rated app without managing infrastructure, Happy Coder is the default community recommendation.

What does Claude Code Remote Control do and what are its limits?

Claude Code Remote Control is Anthropic's native answer to mobile agent access, available on all Claude plans since February 2026. When you start a Claude Code session in your terminal, Remote Control creates a bridge so you can continue that session from the Claude iOS or Android app.

What it does well: No third-party infrastructure — only the Anthropic relay. Your machine never opens inbound ports. Push notifications tell you when a task completes or needs input. No additional cost beyond your existing Claude plan. Zero setup beyond having the Claude app.

Its core limits: You cannot start a new Claude Code session from mobile — only continue one already running on your machine. Session times out if your machine goes offline or the terminal is closed. Claude Code only — no Codex, no OpenCode. Recurring friction documented on r/ClaudeCode: "QR code every time. Even for projects I connect to daily." — each reconnect requires re-scanning rather than resuming a saved connection.

Remote Control is the right default if you're already on a Claude plan, primarily use Claude Code, and want zero-setup mobile monitoring. It fails for use cases requiring starting fresh sessions remotely, long unattended runs, or access to Codex or OpenCode.

What is the closed laptop problem and which tools solve it?

The "closed laptop problem" is the central unsolved pain point for mobile coding agent access: every local remote-control approach fails when your machine goes to sleep. Close the lid, kill the session. Developers on r/ClaudeCode: "Terminal has to stay open. If my laptop sleeps or I close the lid, the session dies."

This separates the architectures cleanly:

• Remote Control: Session ends when your machine goes offline or the terminal closes. Close the lid, session is gone.
• Happy Coder: Agent process lives on your laptop. No laptop, no agent.
• Omnara: Local by default. Cloud-sync feature can migrate sessions before sleep, but requires account setup and configuration.
• Grass cloud VM: Agent runs on a Daytona workspace in the cloud. Laptop state is completely irrelevant.
• Cursor Mobile: Session managed in Cursor's cloud. Cursor IDE required.

For long-running overnight tasks or parallel autonomous builds, only cloud VM approaches structurally solve the problem. For supervised work where you're near your machine, local relay tools work fine. See How to Monitor a Long-Running Coding Agent Overnight for practical patterns that work across both architectures.

What is Control-PC-Terminal, the new June 2026 entrant?

Control-PC-Terminal surfaced in r/TopAutomationTools and r/buildinpublic in June 2026, currently in early access. Reddit threads describe it as a terminal control layer for remote agent sessions, positioned as a developer-friendly alternative to raw SSH terminal emulators on mobile. Specific agent support and architecture are not yet publicly documented at the level of the established tools in this comparison. Worth tracking as it matures — not ready for production evaluation based on available information as of June 2026.

The broader category pattern: every established tool in this table launched between August 2025 and June 2026. This is a brand-new market consolidating fast — the comparison table above will look meaningfully different in six months.

FAQ

Is there a Claude Code iOS app?
There is no dedicated Claude Code iOS app from Anthropic. The Claude iOS app includes Remote Control (for continuing an existing terminal session) and Dispatch (for delegating tasks), but not a full Claude Code agent session with local file access and autonomous tool execution. Third-party options — Grass, Happy Coder, Omnara — provide mobile agent access as independent iOS apps with different architectural approaches.

Does Claude Code work on Android?
Claude Code Remote Control works via the Claude Android app in the same way as iOS — continue a running session, cannot start a new one. Happy Coder and Omnara have Android apps. Grass's mobile app (React Native / Expo, open-source MIT) supports Android. Note: running Claude Code natively on Android via Termux is not supported — Claude Code requires an x86_64 environment, and Termux's ARM userland without glibc blocks native execution. This makes cloud-based approaches the practical path for Android-first developers.

What is the best app to control coding agents from mobile in 2026?
It depends on your use case. For agent-agnostic access to Claude Code, Codex, and OpenCode from one interface — with sessions that survive your laptop closing — Grass (codeongrass.com) is the only option. For the highest-rated app focused on Claude Code and Codex, Happy Coder (4.9/5, MIT licensed). For the widest feature set including Apple Watch and voice mode, Omnara (YC S25, free tier). For zero-setup within the Anthropic ecosystem, Remote Control.

Can I start a new Claude Code session from my phone?
Claude Code Remote Control does not allow starting new sessions from mobile — only continuing existing ones already running in your terminal. Grass (both local CLI and cloud VM), Omnara, and Cursor Mobile allow starting fresh sessions from the phone. Happy Coder requires session initialization from the desktop before connecting from mobile.

What does BYOK mean for mobile coding agent apps, and which tools support it?
BYOK (Bring Your Own Key) means your API key lives in your environment and never passes through the tool provider's infrastructure. Grass enforces BYOK by architecture — the agent runs inside your VM, and your ANTHROPIC_API_KEY never leaves it. Happy Coder's E2E encryption means its relay cannot access your API traffic. Omnara routes session events but not raw API calls through its servers. Remote Control routes through Anthropic's own infrastructure exclusively. BYOK matters because API keys are credentials — any intermediary that handles them can, in principle, use them.
