Cosyra vs Moshi: Hosted Container vs SSH Client

Short answer. Moshi is a polished iOS, iPadOS, macOS, watchOS, and Android terminal client that connects to a server you own and keep awake; the AI coding agents run on that server, not in the app. Cosyra is a native iOS and Android app paired with a managed Ubuntu 24.04 container that already has Claude Code, Codex CLI, OpenCode, and Gemini CLI installed. They are not the same category. Moshi is the best front-end for a server you already run. Cosyra is the shape of the problem where you do not want to run the server at all.

We compared the two after a Moshi link kept showing up in the "best iOS terminal for AI coding agents" results next to our own guides. We read Moshi's site and setup articles, pulled the App Store listing, and lined its architecture up against how we actually run Cosyra from an iPhone on the train. The honest version of this comparison hinges on one question (do you already have a server?), so that is where we start.

This post was written by the Cosyra team. We compared Cosyra against Moshi based on hands-on use of Cosyra on an iPhone and first-hand reads of getmoshi.app, Moshi's "Mac as a remote endless working agent" setup article, and the App Store listing (id 6757859949), all verified 2026-05-21. Where Moshi has not published a number, we say so rather than guess.

Why is "Cosyra vs Moshi" really a client-vs-host question?

The single fact that decides this comparison: Moshi is a client, Cosyra is the host. Moshi gives you a terminal on your phone and connects it over SSH or Mosh to a machine you provide. Cosyra is the machine: a per-user Ubuntu 24.04 container running on Azure AKS that we manage. Both put a shell in your pocket, but the compute lives in completely different places, and so does the work of keeping it alive.

This is not us spinning Moshi's design into a weakness. It is Moshi's own framing. The tagline on getmoshi.app is "The mobile interface for AI coding agents. Zero desktop install." The "zero install" is about the client you put on your phone; you still bring the server. Their guide for running an always-on agent is explicit about it: "Your Mac sits on your desk running an AI agent in a tmux session," and "Your Mac needs to stay awake and accessible," with caffeinate and "Prevent automatic sleeping when the display is off" as the prescribed setup. That is a perfectly good architecture. It is just a different one from ours.

How do Cosyra and Moshi compare feature by feature?

Cosyra ships a hosted Ubuntu 24.04 container with the agents pre-installed at $29.99/month; Moshi is a $6.99/month client app that connects to a server you bring and keep running. The table below lines them up on thirteen attributes, verified 2026-05-21. Read the pricing row as "Moshi's price plus your own server," because that is the real all-in cost.

What does Moshi actually cost once you add the server?

Moshi's $6.99/month is the most quoted number in any "Moshi vs" thread, and on its own it makes Cosyra's $29.99 look expensive. The comparison only holds if you ignore the server, which Moshi requires and Cosyra includes. Here is the honest math, with the caveat that your server cost depends entirely on what you already have.

• If you already run a Mac or VPS 24/7: Moshi is genuinely cheaper. $6.99/month (or $79.99 once) for the client, and your server is a sunk cost you were paying anyway. This is the case Moshi is built for, and it is a good deal.
• If you would have to rent a box for this: a small always-on VPS runs roughly $4–$24/month depending on RAM, and you maintain it: updates, reboots, keeping it awake. Add that to Moshi's price and the gap to Cosyra's flat $29.99 (container + 120 hours of compute + 30 GB storage + agents installed) narrows or closes, before you count your own time.
• If you use a Mac you leave on: there is no line item, but there is the "is it still awake, did it reboot after the power blip, is my home IP still reachable" tax. We have lost agent sessions to exactly that. A managed container does not have that failure mode.

None of this makes Moshi a bad buy. It makes the headline-price comparison misleading. The fair question is total cost and total upkeep for your situation, and we walk through the broader version of that trade-off in our mobile coding terminal guide.

Where does Moshi beat Cosyra?

Moshi beats Cosyra on native-iOS control polish, server ownership, headline price when you already have a box, and reach onto macOS and Apple Watch. We ship a web-and-app product backed by a cloud container, and on these specific axes Moshi's client-first design wins. We are not going to pretend otherwise.

• Native-iOS control surface for agents. Live Activities and Dynamic Island surface a running agent on your lock screen; Apple Watch lets you approve an action from your wrist; on-device Whisper turns a spoken prompt into terminal input. For driving an agent that is mostly doing the typing, that approval-from-anywhere loop is a genuinely nice surface, and it is more app-native than our terminal view.
• You keep full control of the server. If you run a beefy Mac with Xcode and a Simulator, or a VPS tuned exactly how you like it, Moshi drives your environment (your toolchain, your hardware, your data residency) instead of a managed container. For some people that control is the whole point.
• No hosted-runtime trust required. Your code never touches a third party's container. If your security posture rules out running code on someone else's managed compute, Moshi's bring-your-own-server model fits where a hosted product cannot.
• Cheaper headline price if you already have a server. $6.99/month, or $79.99 once for lifetime, against Cosyra's $29.99/month. If the server is already running, that is a real saving.
• macOS and Apple Watch clients. Moshi runs on iOS, iPadOS, macOS, watchOS, and Android. Cosyra is iOS, Android, and web. If you want a Mac-native client or a Watch app, Moshi has them and we do not.

Where does Cosyra beat Moshi?

Cosyra beats Moshi on having no server to own or keep awake, AI coding agents pre-installed, persistent cloud storage that survives device loss, and a container that follows you across devices. The trade-off for "best mobile client for a server you own" is that you have to own, run, and keep that server alive.

There is no server to keep awake

This is the one that bites in practice. Moshi's own endless-agent guide tells you to run caffeinate, enable "Prevent automatic sleeping when the display is off," and "Start up automatically after a power failure," because the agent only runs while your machine does. With Cosyra the container is the product. It hibernates on idle and resumes exactly where you left off when you reopen the app, so there is no "did my Mac go to sleep on the train" question, because there is no Mac of yours in the loop.

AI coding agents already installed

Every Cosyra container boots with Claude Code, Codex CLI, OpenCode, and Gemini CLI on PATH. With Moshi, you SSH into your own box and install and update each agent yourself:

On Cosyra the same start is shorter, because the install already happened in the image:

We walk through that first session in How to Run Claude Code on Your Phone and the OpenAI-side equivalent in Codex CLI on your phone.

Persistent storage that survives losing the device

Cosyra gives every user 30 GB of cloud storage attached to the container. Drop your phone, buy a new one, log in, and your repo, shell history, and half-finished agent session are still there. With Moshi, persistence is whatever your server provides, which is fine if your server is solid, and a problem if it is a home Mac that just rebooted.

One environment across iPhone, Android, and web

A Cosyra container is the same container whether you reach it from an iPhone, an Android tablet, or a laptop browser. Moshi's reach is broad on the client side (it even has a Watch app), but the environment still lives on the single server you pointed it at, and your local keys and config live on each device. If you also carry a Pixel, we ship a native Google Play app backed by the same container.

An opinion a Moshi fan would disagree with

We think "bring your own server" is the wrong default for mobile agent coding, not a feature. The whole reason to code from a phone on the train is to remove friction, and a server you have to provision, patch, and keep awake adds a standing chore that fails at the worst time, mid-tunnel, when the Mac at home picked that moment to install an update. Moshi fans value the control that chore buys. We think for most people the control is not worth the upkeep, which is exactly the bet Cosyra makes.

Who should pick Moshi instead of Cosyra?

Pick Moshi instead of Cosyra if you already run a server you love, you live deep in the Apple ecosystem and want the Watch and macOS clients, or you have a hard requirement that your code never run on someone else's managed compute. Moshi is the right answer for those profiles, and it is a well-built client.

Try Moshi first if you are one of these

• You already keep a Mac or VPS running 24/7. The server is a sunk cost, the agents are already installed, and you just want the best mobile front-end to it. Moshi's $6.99/month (or $79.99 lifetime) buys exactly that, with Live Activities and Apple Watch approvals on top.
• You want a Watch or macOS-native client. Approving an agent action from your wrist, or driving the same sessions from a Mac app, is something Moshi ships and Cosyra does not.
• Your code cannot run on managed third-party compute. If policy or preference says the code stays on hardware you control, Moshi's bring-your-own-server model is the honest fit and Cosyra's hosted container is not.

We genuinely like Moshi as a client. If we already ran a tuned home server, we would point it at one. The reason we built Cosyra is that most people who want to code from a phone do not want to run that server in the first place.

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

You try Cosyra from a Moshi 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 installed. There is no server to provision, no SSH key to add, no machine to keep awake. Your model API keys port directly.

If you keep SSH hosts for your own boxes, you can still reach them from inside the Cosyra container with plain ssh, since we ship openssh-client. The common pattern: Cosyra for the day-to-day environment, and ssh out to a legacy box for the one thing that only runs there. The Moshi-style flow (drive an agent on your own Mac) and the Cosyra flow are not mutually exclusive.
