Cosyra gives you your own Linux computer in the cloud and a phone app built for running AI coding agents on it. Chat with Claude Code, Codex, Cursor or OpenCode while they work on your projects, browse the files they change, preview what they build, dictate by voice, and open a full terminal whenever you want one. YOUR OWN MACHINE • A persistent Ubuntu machine with 30 GB of storage. Your repos, tools, dotfiles and agent sessions stay exactly where you left them. • Sleeps when idle and wakes in seconds. • 4 GB of RAM on Core, 8 GB on Pro. Nothing depends on your phone's CPU or battery. • git, node, python and the rest of a normal developer toolchain, plus whatever you install. AGENTS, NOT A CHATBOT • Run Claude Code, Codex, Cursor or OpenCode on your machine and talk to them from your phone. • The agent edits files and runs commands with the permission level you choose. • Queue follow-ups, steer work in progress, and switch agents on the same project. • A running turn survives a dropped connection, and you get a notification when unattended work finishes. PROJECTS, FILES AND PREVIEWS • Link GitHub, clone repositories, open projects, switch branches, and inspect diffs. • Browse and read files without typing paths. • Preview the web apps your agents build through a secure, authenticated tunnel. VOICE • Dictate prompts. Speech is recognized on your device and tidied up before it reaches the agent. A FULL TERMINAL WHEN YOU WANT ONE • xterm-compatible terminal with smart keys, scrollback restoration and truecolor. • Sessions keep running while the app is in the background and reconnect where they stopped. BRING YOUR OWN MODELS Connect Anthropic, OpenAI or another supported provider with your own API key or eligible subscription. Your subscription pays for the machine, not the model. Cosyra never resells model access. PLANS Core (4 GB RAM) and Pro (8 GB RAM), both with 30 GB of storage and a 7-day free trial. A subscription is required for machine access. Pricing is shown in the app before you start a trial. PRIVACY AND SECURITY • Provider API keys travel over TLS to encrypted server-side storage and are never saved on your phone. • Every machine runs in its own isolated sandbox. • Voice recognition runs on the device. • Sign in with Apple, Google or GitHub. Claude Code is a product of Anthropic, Codex of OpenAI and Cursor of Anysphere; OpenCode is an open-source project. Cosyra is not affiliated with or endorsed by any of them.
