Run Cline on Your Phone (iPhone + Android)

You can run Cline on your phone today, iPhone or Android, but not with a Cline app — there isn't one. Cline is an open-source AI coding agent that lives inside a desktop IDE (a VS Code extension, a JetBrains plugin, a CLI, and an SDK), with no native mobile build at all. The fastest path: install Cosyra for iOS or Cosyra for Android, open the Ubuntu container, install the Cline CLI with npm i -g cline, run cline auth with your own provider key, then cline. Cline is not one of the agents we pre-install, so this is the guide where you add it yourself. 1 hour free on Cosyra signup, no credit card.

This guide was written by the Cosyra team. We installed and ran the Cline CLI inside a Cosyra container from a phone, and we cross-checked every claim about Cline against the official cline/cline repo, the Cline CLI docs, and cline.bot/pricing, verified 2026-06-08.

What is Cline?

Cline is an open-source autonomous coding agent that runs inside your editor: it reads and edits files across a project, runs shell commands with live output, and works through a Plan-and-Act loop with an approval workflow. The repo at cline/cline had 62,912 GitHub stars when we checked on 2026-06-08, is Apache-2.0 licensed, and is one of the largest AI coding agents by reach, with the homepage citing "8.0M+ installs." The IDE release was v3.88.1 (2026-06-07); the standalone npm CLI package cline was at 3.0.20.

Cline ships five ways, and all of them are desktop: a VS Code extension, a JetBrains plugin, the cline CLI, an SDK, and a Kanban web board for orchestrating tasks. It runs on macOS, Windows, and Linux, and it also works inside Cursor and Windsurf, which are themselves VS Code forks. What it does not have is any mobile surface — no native iOS, iPadOS, or Android app, verified 2026-06-08. The Kanban board is a task view in a browser, not an editor or terminal you can drive a session from.

The opinion we hold that Cline's core audience will push back on: if you want Cline "on your phone," the honest move is to stop tying the agent to a laptop you have to keep awake. The desktop extension is genuinely excellent at a desk — multi-file diffs and the Plan/Act approval flow inside a real editor beat a phone terminal when you're sitting down. But the agent doesn't need the editor to run; it needs a shell, a package manager, and network access. Put the CLI on a cloud box that is already always on, and you can kick off a Cline session from the train without leaving VS Code open on a machine at home.

How can you run Cline from a phone?

There are three honest ways to reach Cline from a phone, and the deciding factor is where the agent process lives: the Cline CLI in a cloud Ubuntu container reached from a native app (Cosyra), the Cline CLI on a VPS you run yourself reached over SSH, or — if you're really at a desk — just the VS Code extension on a laptop. Comparison current as of 2026-06-08.

1. Cosyra: run the Cline CLI in a cloud container

This is what we built: a native iOS and Android terminal connected to a persistent Ubuntu 24.04 container. Claude Code, Codex CLI, OpenCode, and Gemini CLI are already installed; Cline is the one you add with npm i -g cline. The container is always on, so the agent has somewhere to run and keep running while your phone sleeps.

• Works when: you want Cline running in the cloud, reachable from both iOS and Android, with no laptop to keep open and no machine to maintain.
• Breaks when: you are offline. The container lives in the cloud, so no internet means no terminal. Full trade-off list in Cosyra vs Termux.
• Cost: 1 hour free on signup, no credit card. Extend with a 10-hour, 7-day trial when you want more. After that, $29.99/month or $300/year. Cline's software is free; your model tokens are billed by your provider. See pricing.

2. Cline CLI on your own VPS over SSH

On iPhone or iPad, an SSH client into a VPS works. Spin up a box, run npm i -g cline on it, SSH in inside a tmux session, and run cline. Most VPS images are x86_64 Linux, so the CLI installs the same way it does on Cosyra; the difference is you are now the sysadmin.

• Works when: you want a box that is yours and an iOS-native keyboard, and you already run server infrastructure.
• Breaks when: you do not want to patch, harden, and back up a server. More in SSH from your phone.
• Cost: the SSH client plus the VPS (about $5 to $40/month). No Android equivalent for the iOS-only SSH clients.

3. Stay on the VS Code extension at a desk

The honest third option: if you're actually sitting at a laptop, don't fight it — use the Cline VS Code extension. Multi-file diffs, checkpoints, and the Plan/Act approval panel inside a real editor are a better editing experience than a phone terminal when you have a keyboard and a big screen. The phone setups above are for when the laptop is the thing you don't have with you. For the full head-to-head on where each one wins, see Cosyra vs Cline.

• Works when: you are desk-bound and want the richest editing UX, free, in the editor you already use.
• Breaks when: you are away from the machine — the extension needs the IDE open and the computer on. That's the gap the cloud container fills.
• Cost: free extension; you pay only inference (BYOK).

How do you set up Cline on iPhone or Android?

You set up Cline on iPhone or Android in about five minutes with Cosyra: install the app, open the container, install the Cline CLI, authenticate your provider, and run a session. The install is one npm command because Node.js is already in the container.

Step 1: Install Cosyra and open a container

Download from the App Store or Google Play. Sign in with Apple, Google, or email. On first launch we provision a fresh Ubuntu 24.04 container with Node.js, Python, Git, and tmux already on it. This is the always-on machine the Cline CLI runs on, so there is no laptop to keep open.

Step 2: Install the Cline CLI

Cline is not one of the four agents we pre-install, so you add it with npm. Node.js is already present, so this is a normal global install with no extra toolchain. We ran this in a fresh container and cline --version reported 3.0.20.

Step 3: Authenticate your LLM provider

Cline is BYOK and model-agnostic. Run cline auth, choose a provider, and authenticate with your own key — Anthropic, OpenAI, Google Gemini, OpenRouter, AWS Bedrock, Ollama, and many OpenAI-compatible endpoints are supported. The credentials land in the container's home volume, so they survive hibernation and are there on every device you sign in from. You can also override the provider and model per run with -P and -m.

Step 4: Start a Cline session

Clone your repository, cd into it, and run cline for an interactive session — or pass the task inline. Cline plans, edits files, runs commands, and checks its own work in the Plan-and-Act loop, then reports back. Because the container is persistent, you can close the app mid-task and reopen later to pick up where it left off.

What can you actually do with Cline on your phone?

The honest pitch for Cline on a phone is an autonomous agent that keeps working while you are not looking at it, in the cloud, without a laptop in the loop. Three sessions we run from a phone.

Kick off a refactor on the train and review the diff later

You have a self-contained chore: migrate a module to async/await. On the train, open Cosyra, cd into the repo, and run cline "refactor src/api/client.py to async/await and update callers". Cline works through the change while you put the phone away. Because the container stays up, the diff and test output are waiting when you check back at the next stop.

Triage a failing test from the couch

Saturday morning, phone in hand, CI is red. Point Cline at the failure: cline "tests/test_invoice.py is failing, find out why and fix it". It reads the traceback, edits the code, reruns the test in the same shell, and reports what it changed. You review the diff on the phone and decide whether to keep it. The Plan/Act approval step means it shows you the plan before it touches anything.

Keep a private repo inside the container

Because Cline is BYOK and the container is yours, a sensitive repo can stay inside the box. Point Cline at the provider you trust, and the code never leaves the container for anything except the model calls you configured. For the cross-agent view of how this compares to the agents we pre-install, see the AI coding agents on mobile pillar.

What are the real limits of running Cline on a phone?

Knowing where this setup stops helps you match it to the right job instead of fighting it.

• No offline mode on Cosyra. The container lives in the cloud, so no internet means no Cline. If you code on planes with no wifi, an agent on local hardware is the only thing that runs there.
• You lose the editor UI. The CLI is the same agent as the VS Code extension, but you give up the inline diff panel and the visual Plan/Act view. On a phone that's a fair trade; at a desk, the extension is nicer. See OpenCode on phone for an agent we do pre-install.
• Not pre-installed on Cosyra. Unlike Claude Code, Codex CLI, OpenCode, and Gemini CLI, you install Cline yourself. It is one command, but it is a command.
• You pay your provider. Cline's software is free and open-source (Apache-2.0), but the tokens are not. Budget for API spend the same way you would on a laptop.
• No Docker-in-Docker guarantee. If a task Cline runs needs docker, verify it works before committing to phone-only.

Who should pick each option?

Choose the VS Code extension if you are at a desk on a capable laptop and want the richest free editing UX in the editor you already use. Choose an SSH client plus a VPS if you are on iOS, you already run a box, and you want full control of the host. Choose Cosyra if you want Cline running in the cloud on both iOS and Android without keeping a laptop open, and you want Claude Code, Codex CLI, OpenCode, and Gemini CLI sitting next to Cline in the same container.
