Coden is a remote control for a coding Agent that works on your own computer. You install the Server on the computer and start it over one project. The phone pairs with it by scanning a QR code — and from that moment you no longer have to be at the desk. WHAT YOU CAN DO • Give it a task and watch what the Agent does, line by line. • Approve or reject every change it wants to write. • Browse the project's files, images and Markdown included. • Run the tests and see what failed. • Open the running application in Preview, as if you were at the computer. • Switch a branch, write a commit, look through the history. THE WORK STAYS WITH YOU Neither the project nor the source code is uploaded anywhere. The Agent runs on your computer, under your account, over the directory you gave it. The phone is a window into it, not storage. The connection between the phone and the computer is end-to-end encrypted. When the two cannot see each other directly, our Service passes the traffic — but it cannot read it, because it has no key to it. NO ACCOUNT There is nothing to register and nothing to sign in to. Nothing to forget. WHAT YOU NEED • A computer with macOS, Windows or Linux, and the Server from coden-app.com • The Claude Code CLI and an Anthropic account — you pay for the Agent directly with them • Git Without the Agent the Server still runs: Documents and Preview work, there is just nobody to give a task to. FREE Both the app and the Server are free. We sell nothing inside the app and collect no analytics.
