Cloud Ubuntu workspace
Cosyra opens a fresh Ubuntu 24.04 x86_64 container on Azure for each account, giving you a real shell rather than a chat wrapper or a local mobile app emulation.
Cosyra
ReivindicarCosyra is a mobile cloud terminal for developers to run AI coding agents from iPhone or Android without managing a VPS, with isolated Ubuntu workspace, persistent storage, and BYO API key billing.
Mobile cloud terminal for AI coding
Cosyra is a mobile cloud terminal for developers who want to run AI coding agents from a phone without managing their own VPS. It provides an isolated Ubuntu workspace that you access through iPhone and Android apps, with browser access also supported on paid plans.
The workspace ships with Claude Code, Codex CLI, OpenCode, and Gemini CLI pre-installed. You bring your own Anthropic, OpenAI, or Google API key, then use the container to inspect code, edit files, review diffs, and continue the same shell session across devices when hibernation is available.
The product is aimed at developers who need a Linux environment in situations where a laptop is inconvenient or unavailable, such as on-call response, commuting, or quick refactors away from a desk. Cosyra emphasizes persistence, isolation, and a standard Ubuntu workflow rather than a lightweight mobile editor.
Core features
Multiple coding agents
Claude Code, Codex CLI, OpenCode, and Gemini CLI are pre-installed, so you can choose the coding agent that fits the task without building the environment yourself.
Bring-your-own API key
The product follows a bring-your-own-key model for Anthropic, OpenAI, and Google accounts, keeping provider billing separate from the Cosyra subscription.
Persistent development state
The container includes 30 GB of persistent storage and keeps files, git state, and shell history inside your workspace between sessions.
Session hibernation
On Pro, the workspace hibernates after ten minutes idle and resumes with state intact, letting you move between phone and other devices without restarting the session.
Multi-device access
The app is available on iPhone, Android, iPad, and web, with sign-in via Apple, Google, or email.
Common use cases
On-call debugging from a phone
Open Cosyra when you need to inspect logs, read a stack trace, change an environment variable, or redeploy without a laptop nearby.
Commute-friendly coding
Use the workspace during a commute to ask an agent for a refactor plan, review the diff later, and keep the same session when you get back to a larger screen.
Lightweight mobile development
Keep a real Ubuntu environment available for days when you do not want to carry a laptop but still need a shell, git, and file persistence.
Agent selection by task
Switch between Claude Code, Codex CLI, OpenCode, and Gemini CLI depending on the task, while keeping your provider account and billing separate.
Cross-device continuation
Start on the phone, continue on iPad or in a browser, and pick up the same workspace state after hibernation on Pro.
Pros and Cons
Pros
- Runs a full Ubuntu container rather than a stripped-down mobile editor.
- Supports multiple coding agents, including Claude Code, Codex CLI, OpenCode, and Gemini CLI.
- Keeps code, files, and shell history in a persistent workspace with 30 GB of storage.
- Offers session hibernation on Pro so work can resume after closing the app or switching devices.
- Available on iPhone, Android, iPad, and web, with App Store and Google Play distribution.
Cons
- The source does not describe shared team workspaces or admin controls, so it appears oriented toward individual use.
- Cosyra uses your own API keys, so model usage and billing are handled separately with Anthropic, OpenAI, or Google.
FAQ
What does Cosyra do?
Cosyra provides a cloud-hosted Ubuntu container that you access from iPhone or Android. It ships with Claude Code, Codex CLI, OpenCode, and Gemini CLI pre-installed, so you can describe changes, review diffs, and approve work from a phone.
Do I need my own API key?
Yes. Cosyra follows a bring-your-own-key model: you paste your Anthropic, OpenAI, or Google API key into the container and pay the model provider directly. Cosyra covers the Ubuntu container, storage, and session features, not model tokens.
Can I use Cosyra to deploy from my phone?
Cosyra is available on the App Store and Google Play. The workspace is a full Ubuntu container, and the site says deploy connectors are available for Vercel, Netlify, Render, Fly.io, Railway, and Cloudflare after pasting a token in Settings.
Can I start on my phone and continue later on another device?
Yes. On Pro, the container hibernates after ten minutes of inactivity and resumes with state intact, even on a different device. The FAQ also says one Cosyra account can be reached from iPhone, iPad, Android, and any browser.
Is Cosyra set up for team use?
Cosyra is designed for individual developer workspaces. The security page describes each account as its own isolated container in a per-user Kubernetes namespace, but the source does not describe team administration or shared-workspace features.
