Cosyra

Run Cosyra AI coding CLIs like Claude Code, Codex CLI, OpenCode, and Gemini CLI in a cloud Ubuntu terminal on your phone with persistent storage.

Cosyra

What is Cosyra?

Cosyra is a mobile cloud terminal that lets you run AI coding tools from your phone in a full Ubuntu Linux environment. It’s designed so you can code from anywhere without relying on a laptop, using a terminal workflow similar to what you’d do on desktop.

In Cosyra, AI coding CLIs—including Claude Code, Codex CLI, OpenCode, and Gemini CLI—run inside a pre-installed, persistent container. You connect your own API keys and use the terminal to edit, run tests, and manage repositories.

Key Features

  • Pre-installed AI coding CLIs: Claude Code, Codex CLI, OpenCode, and Gemini CLI are included so you can start coding workflows without manual setup of each tool.
  • Full Linux terminal in the cloud: The app provides a full Ubuntu Linux terminal environment rather than a limited shell.
  • Persistent storage (30 GB): Your files persist between sessions, so projects don’t reset when you close and reopen the app.
  • Common developer tools available: The container includes Node.js, Python, Git, tmux, and vim, along with standard dev tools used for typical coding and debugging tasks.
  • Session hibernation for Pro: Pro sessions pause after inactivity (10 minutes) and resume where you left off.

How to Use Cosyra

  1. Install Cosyra from Google Play or the App Store.
  2. Set up the cloud terminal (the site references a quick tutorial) to initialize the terminal environment.
  3. Connect your AI provider access by bringing your own API key (Cosyra uses a bring-your-own-key model).
  4. Open the terminal and run your tools. The site shows using Claude Code from the terminal and demonstrates typical workflow commands.

Use Cases

  • Refactor and iterate on auth logic from a phone: Use an AI coding CLI in the terminal to refactor code (e.g., extracting helpers and updating error handling), then run tests like npm test to validate changes.
  • Review and manage pull requests on the go: Use Git and PR tools in the terminal to inspect pull requests, read comments, and review changes without switching to a laptop.
  • Clone and work on repositories from mobile: Start a project by cloning a repo, use tmux/vim for an interactive workflow, and run build/test commands directly in the cloud terminal.
  • Continue work across app sessions: Because storage is persistent, you can stop and resume work later with the same files; Pro users additionally get container hibernation after inactivity.

FAQ

  • Can I run Cosyra on iPhone? Yes. The site states Cosyra works on both iOS and Android with the same terminal experience.

  • Which AI coding tools does Cosyra include? Cosyra comes with Claude Code, Codex CLI, OpenCode, and Gemini CLI pre-installed.

  • Do I need to bring my own API keys? Yes. Cosyra uses a bring-your-own-key model so you can use your own provider accounts.

  • Does my code and files stay available between sessions? Yes. The app provides persistent storage, and the site states files persist between sessions.

  • Is Cosyra only suitable for public code? The site says each user gets an isolated cloud container and that your code and files are private to your environment.

Alternatives

  • SSH into your own server or VPS: You can run coding tools on a machine you control, but you’ll need to manage infrastructure and network access rather than using a ready-to-use mobile environment.
  • Local coding on a phone with an editor/IDE and remote APIs: This can work for lightweight tasks, but a full Ubuntu-style terminal with persistent storage and the pre-installed toolset may be harder to replicate.
  • Cloud development environments (browser-based terminals): These offer remote terminals too, but the workflow and availability on mobile may differ from Cosyra’s phone-first setup.
  • Desktop IDEs with AI coding integrations: Useful if you primarily work on a computer, but it doesn’t address the “no laptop required” mobile workflow Cosyra targets.
