Run Devin Desktop on Your Phone (iPhone + Android)

You cannot run Devin Desktop on a phone, because Devin Desktop (formerly Windsurf) ships desktop builds only: macOS, Windows, and Linux. There is no iOS, iPadOS, Android, or browser build of the editor. What you can do is run the same thing it gives you at a desk, the agent CLIs it drives over ACP, on a phone: open a cloud Ubuntu container from Cosyra for iOS or Cosyra for Android and run Codex CLI, Claude Code, OpenCode, or Gemini CLI, pre-installed. 1 hour free on signup, no credit card.

This guide was written by the Cosyra team. We cross-checked every claim about Devin Desktop against the official Devin Desktop page, the rename announcement, and the Devin Desktop FAQ, all verified 2026-06-06. Where Devin Desktop is genuinely ahead of us, we say so.

What is Devin Desktop (and what happened to Windsurf)?

Devin Desktop is the editor that used to be called Windsurf (and Codeium before that). Cognition AI, the company behind the autonomous engineer Devin, renamed it on 2026-06-02. If you type windsurf.com today you get a 308 redirect to devin.ai/desktop, and the FAQ says it directly: "Devin Desktop is the new name for Windsurf." The migration was an over-the-air update, so anyone already on Windsurf kept their plan, pricing, and extensions. We lead with this because it is the first thing a knowledgeable reader checks, and a post that still calls it Windsurf in 2026 has already lost their trust.

The editor itself is a proprietary VS Code fork for macOS, Windows, and Linux, with Cascade, multi-file edits, and Tab autocomplete inherited from the Windsurf lineage. What pulls people toward "Devin Desktop on phone" searches is the agents. The headline feature now is the Agent Command Center, the desktop tagline reads "Manage fleets of local and cloud agents from one surface." It runs external agents over the Agent Client Protocol (ACP), and the launch blog lists the at-launch agents as "Codex, Claude Agent, OpenCode, and any other ACP-compatible agents." Three of those, Codex CLI, Claude Code, and OpenCode, are exactly the agents we pre-install in a Cosyra container. The gap is not the agents; it is the surface. Devin Desktop runs them at the desk and nowhere else.

The opinion we hold that a Devin Desktop loyalist will push back on: for mobile coding, the editor window is the wrong unit to obsess over. The Agent Command Center, the Spaces and Kanban views, the Cascade panel, all of it assumes a real keyboard and a desk. On a phone you are not getting that window anyway, so the question that matters is not "which editor" but "where do the agents run." People who think the editor chrome is the point will disagree. We think, on a phone, the agent's location is the whole game, and a hosted Linux box you reach from a native app beats an editor with no mobile build at all.

The two Devin surfaces, and why only one of them is the editor

Cognition ships two different things with "Devin" in the name, and conflating them is the easiest way to get this wrong. Keep them separate:

• Devin Desktop is the editor, formerly Windsurf. It is desktop-only, and it is the product these "on a phone" searches are actually about. No iOS, iPadOS, Android, or browser build exists.
• Devin (the cloud agent) is Cognition's autonomous engineer, reachable via app.devin.ai, Slack, Linear, a CLI, and an API. You can open that dashboard in a phone browser, the way you can poke Cursor's web agent, but it queues and reviews autonomous runs. It is not an interactive terminal or editor you type code into on the phone.

So when someone asks "can I run Devin on my phone," the precise answer depends on which Devin: the editor has no phone client at all, and the cloud agent's web dashboard opens in a browser but is not a shell. Neither gives you the thing you get at the desk, an editor with the agent CLIs running in your workspace. That is the gap a cloud container fills.

Why is there no Devin Desktop on a phone?

There is no Devin Desktop on a phone because it has never shipped a mobile build, and nothing in the launch material points to one coming. The desktop page leads with "Download for MacOS" and references macOS, Windows, and Linux installers; the FAQ covers the same three platforms. There is also a "Windsurf for JetBrains" plugin for IntelliJ, PyCharm, and WebStorm, but a JetBrains plugin is still a desktop surface, not a phone one.

It is fair to ask whether the cloud agent counts as "Devin away from your machine." It does not solve the phone problem the way people mean it: the cloud agent runs autonomously and reports back, but the interactive editor, the place you read a diff and steer the agent line by line, is the desktop app. There is no client you type into on iOS, iPadOS, or Android.

How do you run Devin Desktop's agents on iPhone or Android?

You run those agents on iPhone or Android by putting the shell in the cloud and reaching it from a native app. With Cosyra that takes about four minutes: install the app, open the container, pick an agent CLI, add your API key, and start a session. The agent CLIs we pre-install are the part that gives you the Agent-Command-Center loop without any setup.

Step 1: Install Cosyra and open a container

Download from the App Store or Google Play and sign in with Apple, Google, or email. On first launch we provision a fresh Ubuntu 24.04 x86_64 container with Node.js, Python, Git, and tmux already on it.

Step 2: Pick the agent CLI you want to drive

Devin Desktop's Agent Command Center runs Codex, Claude Agent, and OpenCode over ACP at the desk. We pre-install those same three plus Gemini CLI, so you do not have to assemble that yourself. Run whichever matches the model you pay for.

Step 3: Add your provider API key (BYOK)

The agents are bring-your-own-key, so you export the key for whichever model you use and write it into your shell config once. It persists in the container's home volume across sessions and across your phone, tablet, and the web. We do not proxy or meter model billing; you pay your provider.

Step 4: Clone a repo and start a session

Clone your repository, cd into it, and start the agent. You describe the change, it edits files and runs commands in the same shell. This is the Agent-Command-Center loop, running on a phone.

Step 5: Keep it running with tmux

Wrap long sessions in tmux so a dropped signal or a locked phone does not kill the agent mid-task. The session keeps running on the container; you re-attach when you come back.

What does this actually feel like on a phone?

The honest pitch is an agent session you can start anywhere and a real shell underneath it. Three places we run it.

A fix on the train, committed before your stop

You noticed a bug on the way out. On the train, open Cosyra, cd into the repo, run codex, and describe the fix. It edits the file and you commit it. By the time you are off the train, the change is a reviewable commit on the branch instead of a note you have to act on at the desk where Devin Desktop lives.

A refactor from the couch with the agent doing the typing

Saturday morning, phone in hand. Point an agent at a module: "split this file into a parser and a formatter, keep the public API the same." The agent runs the edits and the tests in the same shell, and you review the diff on the phone before keeping it. The small on-screen keyboard barely matters because you are describing intent, not typing every line. This is the part of the Agent Command Center that survives the move to a phone.

Checking a long task from the waiting room

You kicked off a build or a long agent run before leaving. From a waiting room, attach to the tmux session and watch it finish, or steer it if it went sideways. The container kept running while your phone was in your pocket. For the cross-agent picture, see the AI coding agents on mobile pillar.

What are the real limits here?

This setup is not Devin Desktop, and it is not trying to be. Knowing where it stops helps you match it to the right job.

• You don't get the Devin Desktop editor. The Cascade panel, the multi-file editing UI, the Spaces and Kanban fleet views, none of that is here. At a desk, Devin Desktop is a strong VS Code-based IDE, and we would reach for it there.
• No fleet management. Devin Desktop is built to orchestrate many local and cloud agents at once and hand off to autonomous Devin. A single mobile terminal runs one agent session at a time per tab; it is not a multi-agent command center.
• No offline mode. The container lives in the cloud, so no internet means no terminal. A locally installed editor keeps working on a plane; this does not. We lay out the local-vs-cloud trade-off in Cosyra vs Termux.
• You pay your provider. The agent CLIs are BYOK, so model tokens are billed by Anthropic, OpenAI, or Google directly. Our subscription covers the machine, not the model.

Who should pick which?

Choose Devin Desktop if you are at a desk and want a polished VS Code-based AI IDE, you want the Agent Command Center to orchestrate fleets of local and cloud agents and hand off to autonomous Devin, or you want the JetBrains plugin path. There is also a free tier and a $20 Pro tier, a lower entry point if you only code at a desk. Devin Desktop is the better tool for the laptop, and we will not pretend otherwise.

Choose Cosyra if you want to actually run those same agent CLIs from your phone on the train, the couch, or a waiting room, you want Codex CLI, Claude Code, OpenCode, and Gemini CLI sitting in one container with no install step, or you want a persistent Linux box that follows you across iPhone, Android, and web at a flat $29.99/mo. Many people run both: Devin Desktop at the desk, Cosyra when the laptop is closed.

Try Devin Desktop first if your work happens almost entirely at a desk, you want a full editor UI around the agents more than a remote shell, or you want to manage many agents in parallel from one window. Several other desktop-only agentic tools land in the same spot and resolve the same way, by running the agent CLIs in a cloud container: the same-product Windsurf on a phone walkthrough, Warp on a phone, Zed on a phone, and Kiro on a phone. For the specific agents Devin Desktop runs over ACP, see Codex CLI on phone, Claude Code on phone, and OpenCode on phone.
