The Best Apps to Control Coding Agents from Mobile (2026)

Eight tools now let you control AI coding agents from your phone — Grass, Anthropic Remote Control, Termly, ADHDev, Happy Coder, CodeVibe, Omnara, and littleclaw — and they solve the problem through architectures that are not interchangeable. The axis that separates them is where your session runs: in an always-on cloud VM, relayed through a server, transmitted directly phone-to-laptop, or mirrored from a terminal. That choice determines what happens when your laptop sleeps, whether you can start new sessions remotely, and who can read your session content and API credentials.

TL;DR: The landscape changed significantly in spring 2026. Anthropic Remote Control — now on all plans, not just Max — lets you continue sessions from your phone but cannot start new ones; your laptop must stay on. Termly (termly.dev) is a new, free, E2EE terminal-mirroring app with the widest agent roster: Claude Code, Gemini CLI, OpenCode, Qwen Code, Copilot CLI, Aider, and more. ADHDev is not a native app — it is a browser dashboard on your local network. Omnara is now fully free. For always-on agent execution that survives laptop sleep, Grass cloud VM remains the only option in this comparison.

Why do developers need mobile control of coding agents?

The demand is almost never about writing code on a phone keyboard. The real problem is agent stalls — developers start multi-hour tasks, step away, and lose all visibility into whether the agent is running, blocked on a permission prompt, or drifted off-task. "The loop I was stuck in: Ask Claude a long task, open reels, come back 5 minutes later, realize Claude has been waiting for me to approve." Any tool that surfaces agent approval gates on your phone solves the actual bottleneck: not mobile coding, but mobile supervision.

The problem landscape has three tiers. First: agents pause for approval while the developer is away — every tool here addresses this. Second: developers want to start new sessions from mobile — Anthropic Remote Control specifically does not solve this despite being the official option. Third: sessions die when the laptop sleeps — only Grass's cloud VM solves this, because the agent runs in the cloud rather than on the local machine.

Official vs. Third-Party: What the Remote Control Launch Changed

Anthropic Remote Control, added to the Claude iOS and Android apps in spring 2026, created a new framing: the official mobile control layer versus third-party clients. Remote Control is a feature inside the Claude app — not a standalone product. It lets you continue Claude Code sessions you started on your laptop, receive push notifications when your agent needs attention (added in v2.1.110), and approve or deny tool calls remotely. The feature launched as Max-only and is now available on all plans.

The key limitation that the official framing can obscure: Remote Control cannot start new sessions from mobile. The most common developer request — "let me fire off a task during my commute" — remains unaddressed by the official solution. Builder.io's analysis put it directly: "The most common request on X isn't make Remote Control better — it's let me start sessions from my phone." Third-party tools including Grass and Termly fill this gap.

A second structural limitation: Remote Control requires your laptop to stay awake and online. If the connection drops, you have a 10-minute reconnect window before the session times out. The official vs. third-party lens also surfaces a capability Anthropic has not matched: agent-agnostic control. Remote Control covers Claude Code only. Grass supports Claude Code, Codex, and OpenCode. Termly supports Claude Code, Gemini CLI, OpenCode, Qwen Code, GitHub Copilot CLI, Aider, and any terminal-based AI.

What architectures exist in the 2026 mobile coding agent market?

How does each tool work?

Grass

Grass is a machine built for AI coding agents — an always-on cloud VM per developer, powered by Daytona, with Claude Code, Codex, and OpenCode pre-loaded. When your laptop closes, the agent keeps running. Grass is agent-agnostic by design: Claude Code, Codex, and OpenCode all run as first-class citizens. One surface. Every agent. Always on.

The local CLI (@grass-ai/ide, open-source MIT) is a distinct surface: run grass start, scan a QR code, and your phone connects directly over WiFi — no cloud relay, nothing leaves your network except the agent's own API calls. BYOK: API credentials authenticate at the cloud VM or local server and never pass through Grass infrastructure. For key security patterns, see How to Store Your API Key Securely When Running Coding Agents on a VPS.

Free tier: 10 hours, no credit card required at codeongrass.com.

Anthropic Remote Control (all plans, spring 2026)

Remote Control lets you continue Claude Code sessions you started at your desk and approve or deny tool calls from the Claude iOS/Android app. Push notifications tell you when the agent needs attention.

What it does not do: cannot start new sessions from mobile. One remote session at a time. Laptop must stay awake and online; 10-minute reconnect window if dropped. No voice mode. No support for agents other than Claude Code. If you need to start sessions from mobile, run agents while your laptop is off, or work with agents other than Claude Code, you need a third-party tool.

Supported agents: Claude Code only | Can start from mobile: No | Cost: All Claude plans

Termly (termly.dev, free)

Termly (termly.dev — not termly.io, the legal compliance company) is a free, E2EE terminal-mirroring app built by solo developer Siarhei Pratasavitski. It mirrors your terminal to your phone with end-to-end encryption — no server can read the content.

The agent roster is the widest in this comparison: Claude Code, Gemini CLI, OpenCode, Qwen Code (added in v1.9.5, April 14, 2026), GitHub Copilot CLI, Aider, and any terminal-based AI. Critical limitation: Termly requires your laptop to stay on — it mirrors a terminal, not a cloud session. Current traction is early: ~1,000 Android downloads, one App Store rating (4.0).

Supported agents: Claude Code, Gemini CLI, OpenCode, Qwen Code, Copilot CLI, Aider, any terminal AI | Cost: Free

ADHDev (browser dashboard — not a native app)

ADHDev is not a native iOS or Android app. It is an open-source, self-hosted browser dashboard accessed from a mobile browser over your local network (LAN). Readers who expect a downloadable app should know this before investing time in setup.

What ADHDev does well: it monitors multiple agents and IDEs simultaneously — the widest IDE roster in this comparison, including Cursor, Google Antigravity, VS Code, Kiro, Codex, Claude Code, and Hermes Agent. "AI coding agents are becoming background workers, but the control layer is still stuck at the desk," said the ADHDev founder at launch. Push notifications and remote access from outside your local network require the paid cloud tier. 25 GitHub stars, AGPL-3.0.

Supported IDEs/agents: Cursor, Google Antigravity, VS Code, Kiro, Codex, Claude Code, Hermes Agent | Cost: Free self-hosted; paid cloud for remote/push

Happy Coder

Happy Coder is an open-source, E2EE direct-connection mobile client for Claude Code — no relay server in the path. 7,100 Android downloads in the last 30 days, 4.95 rating, 2,100 ratings. The free tier covers core Claude Code control. The Plus plan ($19.99/month in the App Store) adds voice agent interaction. A known reliability issue from March 2026: permission approvals sometimes fail to persist on Bash tool calls with Codex. P2P requires your laptop to stay on; Tailscale is recommended for remote access.

Supported agents: Claude Code | BYOK: Yes (P2P) | Cost: Free / $19.99/mo Plus

CodeVibe (April 2026, P2P + E2EE)

CodeVibe is a native iOS and Android mobile agent client with end-to-end encryption — your session content is encrypted between your phone and your machine so no intermediary can read it. This makes it architecturally distinct from Omnara's cloud relay model. Launched April 2026. Supports Claude Code, Codex CLI, and Gemini CLI — one of two tools in this comparison with Gemini CLI support (the other is Termly), and the only dedicated native iOS and Android app with Gemini CLI support.

Supported agents: Claude Code, Codex CLI, Gemini CLI | BYOK: E2EE in transit; relay cannot read content

Omnara

Omnara is a cloud relay client with voice agent interaction as its standout capability. Omnara founder Kartik: "Voice input + output sounds gimmicky, but it's quite useful for mobile coding." Session content is stored in Omnara's database by design — a co-founder confirmed: "Two of the main features we're investing heavily into are remote sandboxes and voice agent support — these wouldn't work with E2EE." Understand this trade-off before using Omnara with sensitive codebases. Omnara is now fully free (see pricing section).

Supported agents: Claude Code | Relay sees content: Yes

littleclaw / Lunel

littleclaw is a full mobile IDE — a different category from every other tool here. All other options supervise an agent running on your laptop or in the cloud; littleclaw targets developers who want to write and run code entirely from their phone. One developer committed from 3,300m while skiing. If mobile supervision is your goal, the other tools apply.

Full Comparison Table

What does Omnara actually cost? ($9 vs $20 vs free — cleared up)

Omnara pricing has confused comparison sites in 2026. Omnara launched in February 2026 at $20/month (documented in the Hacker News launch thread). A $9/month Pro tier appeared in the README of a now-deprecated Python wrapper. Several articles published in March–May 2026 still quote one of these figures.

The current answer as of May 2026: Omnara is fully free, with unlimited sessions. The Omnara website FAQ states directly: "Yes. Omnara is 100% free, with unlimited sessions." Any article citing $9/month or $20/month is outdated. If you see another comparison quoting a paid price, check the publication date.

What is the difference between BYOK and E2EE?

BYOK (bring your own key) and E2EE (end-to-end encryption) are distinct security properties that many comparisons conflate.

BYOK means your API credentials authenticate at the agent's runtime (your laptop or cloud VM) and are never stored or proxied by the mobile app's infrastructure. Grass and Happy Coder are both BYOK-native: the service never receives your API key at any point.

E2EE means session content is encrypted between your phone and your machine — the relay cannot read it. Happy Coder and CodeVibe have E2EE. Termly also uses E2EE for terminal mirroring.

Omnara has neither by architectural design: session content passes through and is stored on Omnara's servers — a disclosed trade-off enabling their voice roadmap. Anthropic Remote Control uses the standard Anthropic API security model.

For teams running parallel agents across sensitive repos, see Run Multiple Coding Agents in Parallel with Git Worktrees for isolation patterns.

Which app should you use?

Laptop needs to be off while agents run. Grass cloud VM is the only current option — the agent runs in an always-on Daytona workspace, keeps going when your machine closes.

You only use Claude Code and want zero extra setup. Anthropic Remote Control is already in your Claude app. Enable it, test the "cannot start sessions from mobile" limitation, and decide if it's enough for your workflow.

You need agent-agnostic coverage across Claude Code, Gemini CLI, Qwen Code, Aider, and others. Termly covers all of them for free. Trade-off: early-stage maturity and the same laptop-dependency every non-Grass tool has.

You want maximum privacy on a trusted network. Happy Coder's P2P E2EE is zero-knowledge by design — strongest organic traction in the category. Voice requires the $19.99/month Plus plan; core is free.

You want cloud relay with E2EE or specifically run Gemini CLI. CodeVibe provides any-network relay with E2EE and Gemini CLI support.

You want voice agent interaction. Omnara is the only tool with voice and is now free. Session content is stored in Omnara's database.

You run multiple IDEs and want a unified monitoring dashboard. ADHDev covers the widest IDE roster but is a browser dashboard, not a native app. Remote access and push notifications require the paid cloud tier.

Frequently Asked Questions

What is the best app to control coding agents from mobile in 2026?

The best app depends on your constraint. For agents that need to keep running when your laptop is off, Grass cloud VM is the only option. For zero-setup permission handling, Anthropic Remote Control is already in your Claude app. For agent-agnostic coverage (Claude Code, Gemini CLI, Qwen Code, and more), Termly is free. For maximum privacy on a trusted network, Happy Coder's P2P E2EE is zero-knowledge. For voice agent interaction, Omnara is now free.

Is Omnara $9 or $20 a month?

Neither — Omnara is free as of May 2026. It launched in February 2026 at $20/month. A $9/month Pro tier appeared in a deprecated Python wrapper README. The current Omnara website FAQ states: "Yes. Omnara is 100% free, with unlimited sessions." Sites still quoting $9 or $20 are outdated.

What are the limitations of Anthropic Remote Control?

Remote Control is available on all Claude plans as of spring 2026. Key limitations: (1) cannot start new Claude Code sessions from mobile — only continue sessions started at your desk; (2) one remote session at a time; (3) laptop must stay awake, 10-minute reconnect window if dropped; (4) Claude Code only; (5) no voice mode. Push notifications added in v2.1.110.

What is ADHDev and why is it not a native app?

ADHDev is an open-source, self-hosted multi-agent monitoring dashboard (AGPL-3.0, ~25 GitHub stars) accessed from a mobile browser over your local network — not a native iOS or Android download. Its standout feature is the widest IDE/agent roster in this comparison: Cursor, Google Antigravity, VS Code, Kiro, Codex, Claude Code, and Hermes Agent. Push notifications and remote access from outside your local network require a paid cloud tier.

Which mobile coding agent app has BYOK?

Grass and Happy Coder are the two BYOK-native tools in this comparison. Grass keeps your API keys on the cloud VM or local server, never passing through Grass infrastructure. Happy Coder achieves the same property through direct P2P. Termly and ADHDev also keep credentials on your machine. Omnara's relay has access to session content, which may include visible API key values.

Can I control Gemini CLI or Qwen Code from my phone?

Yes. Termly supports Claude Code, Gemini CLI, OpenCode, Qwen Code (v1.9.5+), GitHub Copilot CLI, Aider, and any terminal-based AI. CodeVibe supports Claude Code, Codex CLI, and Gemini CLI. All other tools in this comparison focus on Claude Code.

What to do next

The category has eight tools across five architectural tiers as of May 2026. The right choice depends on which constraint you hit first.

If agents need to run when your laptop is off, start with Grass's free tier — 10 hours, no credit card at codeongrass.com. Grass is agent-agnostic: Claude Code, Codex, and OpenCode run on the same always-on cloud VM.

If you only use Claude Code and need to handle occasional permission prompts, Anthropic Remote Control is already in your Claude app — test the "cannot start sessions from mobile" limitation against your real workflow before investing in third-party tooling.

If you run mixed-model workflows across Claude Code, Gemini CLI, Qwen Code, or Aider, Termly is free and requires no subscription. Verify phone and laptop are on the same network before committing to any P2P or LAN-only tool.

The comparison table above reflects the eight-tool, five-architecture state of the market as of May 2026.
