Frequently Asked Questions
Questions about running AI coding agents, Linux terminals, and developer workflows from a phone.
What is a mobile cloud terminal for AI coding?
Cosyra is a mobile cloud terminal for developers who want a Linux environment on a phone. It runs a cloud-hosted Ubuntu container and lets you use Claude Code, Codex CLI, OpenCode, and Gemini CLI from iPhone or Android without setting up your own server. See what a mobile coding terminal is for the category breakdown.
Can you code from a phone with AI coding agents?
Yes. With AI coding agents, you describe the change you want in plain language, the agent writes the code, and you review and approve the diff. The phone keyboard matters less because you are directing the workflow instead of typing every line by hand. See how developers actually use Cosyra.
Which AI coding CLIs can I run from a phone?
Cosyra ships with Claude Code, Codex CLI, OpenCode, and Gemini CLI pre-installed. You bring your own API keys from Anthropic, OpenAI, or Google. The Ubuntu container also includes Node.js, Python, Git, tmux, and vim, so you can add other CLI tools that fit the environment. Read the AI coding agents on mobile guide for each agent's mobile setup.
How is running Claude Code on a phone different from desktop?
Cosyra lets you use Claude Code from a cloud container that you access on your phone. The workflow is still terminal-based, but mobile input, screen size, and session resume behavior make it a better fit for review-and-direct workflows than long manual typing. Our Claude Code on phone guide walks through the workflow end to end.
Do I need my own Anthropic, OpenAI, or Google API key?
Yes. Cosyra follows a bring-your-own-key model so you use your own Anthropic, OpenAI, or Google accounts. That keeps provider usage and billing tied to your own account instead of bundling model costs into Cosyra.
Can I use a mobile cloud terminal on iPhone and Android?
Yes. Cosyra is available on the App Store and Google Play. You get an isolated Ubuntu container with Claude Code, Codex CLI, OpenCode, and Gemini CLI pre-installed, accessible from both iPhone and Android.
How is a mobile cloud terminal different from SSH apps or Termux?
Cosyra includes the managed cloud environment, so you are not maintaining your own server or depending on a local Android shell. That makes it a better fit for people who want a phone-first Linux environment for Claude Code, Codex CLI, and similar tools. Read the full Cosyra vs Termux comparison and Cosyra vs CloudCLI for the hosted-terminal head-to-head.
What can I build from a phone with Claude Code, Codex CLI, or Gemini CLI?
You can fix bugs, ship features, refactor code, write tests, review pull requests, and update documentation. Cosyra is aimed at agent-assisted workflows where you direct the work and review the output from a phone. Some repositories still need heavier services or project-specific system dependencies, so verify your repo requirements before relying on a phone-only setup. See use cases for on-call engineers, commuters, and no-laptop developers.
How private is my code in a managed cloud terminal?
Your code lives in your own isolated cloud container. Each user gets a separate environment, and API keys are stored on-device with platform-native encryption. Provider usage stays tied to the Anthropic, OpenAI, or Google account you choose.
How much does a phone-based cloud coding terminal cost?
Cosyra includes a free trial of 10 hours or 7 days of full access. After the trial, Pro is $29.99/month or $300/year and includes 120 hours/month of compute, 30 GB of persistent storage, and session hibernation. Subscriptions are available via in-app purchase.
