Cosyra vs Windsurf (Devin Desktop): Code From a Phone

Short answer. Cosyra vs Windsurf is really two different shapes, not a head-to-head. Windsurf is now Devin Desktop — Cognition renamed the editor on 2026-06-02, and windsurf.com redirects there. It is a top-tier desktop AI IDE whose Agent Command Center runs Codex, Claude Agent, and OpenCode over the Agent Client Protocol. But it ships for macOS, Windows, and Linux only, with no iOS, iPadOS, Android, or browser build. Cosyra is a hosted Ubuntu container reached from native iOS and Android apps, with Claude Code, Codex CLI, OpenCode, and Gemini CLI pre-installed. At a desk, use Devin Desktop. If the device in your hand is a phone, we think Cosyra is the better fit.

We wrote this after running the same agent loop both ways: drive a coding agent through Devin Desktop's Agent Command Center on a Mac at a desk, then drive the same kind of session from a cloud container on an iPhone on a train. Both are good. Only one of them runs when there is no laptop in front of you.

This post was written by the Cosyra team. We compared Cosyra against Windsurf, now Devin Desktop, based on hands-on testing of both — Devin Desktop on macOS, Cosyra on iPhone and Android — plus first-hand reads of devin.ai/desktop, the Devin pricing page, the rename announcement, and the Devin Desktop FAQ. Devin Desktop facts and pricing were re-verified first-hand on 2026-06-07; windsurf.com still 308-redirects to devin.ai/desktop.

Wait — isn't Windsurf called Devin Desktop now?

Yes, and any honest 2026 comparison has to start there. On 2026-06-02, Cognition renamed the Windsurf editor to Devin Desktop. The old domain windsurf.com 308-redirects to devin.ai/desktop, and Cognition's FAQ says directly that Devin Desktop is the new name for Windsurf. The change arrived as an over-the-air update; plans, pricing, extensions, and settings carried over, so existing Windsurf users woke up running Devin Desktop with no migration steps. Windsurf itself was previously Codeium, so this is the second rename of the same lineage.

We use both names below the way a reader would: "Windsurf" is still the query people type, "Devin Desktop" is what the product is called today. One thing the rename did not change is the platform story — there was no mobile app before, and there is no mobile app after. That is the gap this comparison is about.

There is one more precision point worth nailing down before the table, because it trips people up. There are two different Devin surfaces. Devin Desktop is the editor, and it is desktop-only. Devin the cloud agent is a separate autonomous engineer you reach from the web at app.devin.ai, Slack, Linear, and a CLI. You can poke a cloud Devin task from a phone browser, but that is a task dashboard, not a terminal where you drive Claude Code yourself. When this post says "Windsurf has no phone client," it means the editor. The cloud agent is a different product with a different job.

How do Cosyra and Windsurf compare feature by feature?

The core difference in Cosyra vs Windsurf is the device. Devin Desktop is a desktop AI IDE that runs on a machine you own; Cosyra is a hosted Linux container you reach from a phone. Devin's price meters agent quota and model usage; Cosyra charges a flat rate for the machine and storage. The table below lines them up on thirteen attributes as of 2026-06-07.

What actually happens when you try to use Windsurf on a phone?

Nothing installs. We opened the App Store and the Play Store and searched for Windsurf and for Devin Desktop; there is no editor app to download, because Devin Desktop ships installers for Mac, Windows, and Linux only. There is no browser build of the editor either. The desktop app manages local and cloud agents from one surface, but that surface is the desktop app; the phone is not a client to it.

So the real test is not "Windsurf on a phone vs Cosyra on a phone"; only one of them exists on a phone. The honest test is the thing Devin Desktop gives you at a desk — an agent surface where you describe a change and an agent edits files and runs commands — while you are away from your laptop. We did exactly that on an iPhone from a train seat. We opened the Cosyra iOS app, dropped into a full-screen Ubuntu shell, typed claude, pasted an Anthropic key, described a refactor, approved the diff, and ran git commit && git push. The agent did the typing; our job was to prompt, review, and approve. That loop is the part of Devin Desktop people miss on mobile, and it is the part a cloud container reproduces, because two of Devin Desktop's at-launch ACP agents (Claude Agent and Codex CLI) are the very CLIs we pre-install.

The honest caveat runs the other way too. On a Mac, Devin Desktop is a genuinely better editor than a plain shell in our container. Its VS Code lineage, Cascade-style multi-file edits, Tab autocomplete, and the Agent Command Center for managing fleets of agents are real ergonomic wins at a desk. We are not claiming Cosyra replaces Devin Desktop on a laptop; it does not, and it is not trying to. The claim is narrower and, we think, more useful: when the laptop is not there, Devin Desktop gives you nothing to install on the phone, and a container gives you a shell with the same agents.

Where does Windsurf (Devin Desktop) beat Cosyra?

Devin Desktop beats Cosyra on desktop editor UX, agent-fleet management, the Devin cloud handoff, a JetBrains path, and a free entry tier. We ship a product that competes for the same agentic-coding job, and Devin Desktop is still the better answer for several real situations. Here are five, each grounded in a first-hand source.

• A top-tier desktop IDE. Devin Desktop is a full VS Code fork with Cascade-style multi-file edits, Tab autocomplete, and a mature extension ecosystem. At a desk, that editing surface beats a shell plus vim in a mobile container, and we use editors like it ourselves on a laptop.
• Local plus cloud agent fleet management. The Agent Command Center (Spaces and a Kanban view) orchestrates many local and cloud agents in parallel from one screen. Cosyra runs agents in shell sessions you split with tmux; Devin Desktop has a purpose-built UI for managing fleets that a terminal does not match.
• The Devin cloud handoff. From the desktop editor you can hand a task to the autonomous Devin cloud agent (reachable from web, Slack, Linear, and CLI) and pick the result back up. That end-to-end editor-to-autonomous-agent pipeline is something Cosyra does not try to be.
• A JetBrains path. "Windsurf for JetBrains" continues as a plugin for IntelliJ IDEA, PyCharm, and WebStorm. If your daily driver is a JetBrains IDE, that is a first-party route Cosyra does not offer.
• A free tier and a $20 entry price. Devin's Free tier is $0 and Pro is $20/month, a lower desk-only entry point than Cosyra's $29.99/month for the hosted machine. If you only ever code at a desk, that is real money saved.

Where does Cosyra beat Windsurf?

Cosyra beats Devin Desktop on the one axis it does not contest: it runs on a phone. Add to that AI CLIs pre-installed, a persistent workspace that follows you across devices, and not needing to supply your own machine. These are different-shape strengths, so we are precise about each.

A real terminal on a phone, not a desktop-only editor

Cosyra gives you an interactive Ubuntu 24.04 shell from the iOS and Android apps. Devin Desktop has no mobile build at all — not iOS, not iPadOS, not Android, not a browser editor. The rename to Devin Desktop did not change that. We did not wait for a mobile editor to appear; we built the phone-native shell that runs the same agents Devin Desktop drives over ACP.

Claude Code, Codex CLI, OpenCode, and Gemini CLI pre-installed

On a fresh Cosyra container, four agent CLIs are already on the PATH. You export a provider key and type claude. Devin Desktop's Agent Command Center is excellent, but it runs those agents inside a desktop editor you have to be sitting at. We pre-install the standalone CLIs because setup friction is the main thing that kills agent-driven mobile coding; nobody wants to npm install a toolchain one-handed on a phone keyboard.

A persistent workspace that follows you across devices

Cosyra containers carry 30 GB of persistent storage and hibernate after 10 minutes idle, resuming in place on next open. The same container is reachable from your iPhone, your Android tablet, and the web: clone a repo on the couch, pick it up from a waiting room, finish at your desk, all in one shell. Devin Desktop edits on whatever machine it is installed on; its state lives there, and there is no hosted workspace that travels with you.

You don't have to supply the machine

Devin Desktop still needs a computer: a Mac, Windows, or Linux box you own and keep running. Cosyra is the machine. There is nothing to leave powered on at home and SSH back into; the container is the thing you connect to. For a developer whose only always-available device is a phone, that removes the biggest hidden dependency in every "use my desktop editor remotely" workaround.

An opinion Cognition's team would push back on

Here is where we disagree with the prevailing AI-IDE view. Devin Desktop leaning harder into the Agent Command Center — managing fleets of agents from a desktop surface — is a reasonable bet for people at a desk. But the assumption underneath it, that serious agent-driven work belongs at a workstation, is the part we think is wrong. When the agent is doing the typing, the human's job shrinks to prompt, review, and approve, and that job fits a phone fine. We think the phone keyboard is fine for agent-driven coding, and most people who disagree have not actually tried driving an agent from a real shell on a train. Cognition's team would likely argue the editor, and the fleet dashboard around it, is where the work belongs; we built Cosyra because we don't think the desk is the only place the work happens.

Who should pick Windsurf (Devin Desktop) instead of Cosyra?

Pick Devin Desktop if you are a desktop-primary developer who wants a top-tier VS Code-based AI IDE, you want to manage local and cloud agent fleets from one editor, you want the Devin cloud handoff, you live in a JetBrains IDE, or you frequently work offline. We use fast native editors ourselves at our desks and Cosyra from our phones; they are not mutually exclusive.

Try Devin Desktop first if you are one of these profiles

• Desktop-primary developer. You code from a laptop or workstation 95% of the time. Devin Desktop's editor, multi-file edits, and Agent Command Center make your daily IDE better in ways a mobile container does not try to. For this shape of use, Devin Desktop is the right answer, not us.
• You want an agent fleet, not a single shell. If your workflow is dispatching many agents in parallel and handing tasks off to the autonomous Devin cloud, the Agent Command Center is built for exactly that. Cosyra is a terminal-first single workspace; it is not a fleet dashboard.
• Frequently offline. You work on planes, in dead zones, or against local-only files. A local editor beats a cloud container the moment the network drops. If a meaningful share of your work is offline, Devin Desktop wins.

We use a fast native editor when we are sitting at a desk and want the nicest editing surface on the machine. We use Cosyra when the only device we have is a phone. Different tools, different places. Choose by where you are, not by which is "better."

How do you try Cosyra if you're coming from Windsurf?

You try Cosyra from a Windsurf or Devin Desktop background in about two minutes: install from the App Store or Google Play, open the app, and you land in a fresh Ubuntu 24.04 x86_64 container with Claude Code, Codex CLI, OpenCode, and Gemini CLI already on PATH. The agents you drive from the Agent Command Center translate directly — two of the at-launch ACP agents (Claude Agent and Codex CLI) are the same CLIs here — and the difference is there is no install step and no machine to keep powered on. The session below shows the commands we run on a fresh install.

If you wrap long editor sessions in a way that survives interruptions, the Cosyra equivalent is tmux: start a named session, detach, and reattach after your phone locks or the connection drops. We walk the whole flow in our guide to running Windsurf's agents on your phone, and the post-rename version in Devin Desktop on your phone. The broader setup is in How to Run Claude Code on Your Phone, and for the full map of mobile coding options the AI coding agents on mobile pillar lays out every route. If your real comparison set is other desktop tools, the same desk-vs-phone logic shows up in Cosyra vs Zed and Cosyra vs Kiro — both are desktop-only agentic tools with the same no-mobile-build gap.
