# FAQ (/docs/faq)



## Where does my code run? [#where-does-my-code-run]

On your machine. Workspaces are real directories with real processes — the
browser is a window onto them, not a remote sandbox. Your code never has to
leave your computer for agents to work on it.

## What does Cento cost to run? [#what-does-cento-cost-to-run]

Your own compute — so effectively nothing extra. Cento coordinates through
the cloud, but builds, dev servers, and agent runs execute locally.

## Does Cento need an open port on my machine? [#does-cento-need-an-open-port-on-my-machine]

No. The daemon dials out and holds an outbound connection. Nothing on your
machine accepts inbound traffic from the internet.

## What are the prerequisites? [#what-are-the-prerequisites]

`git`, `bash`, `curl`, and CA certificates — present by default on macOS and
nearly every Linux. Cento installs its own toolchain (Node, Bun, tmux) in its
own directory; it does not touch your system's versions.

## How do I uninstall a machine? [#how-do-i-uninstall-a-machine]

To disconnect a computer, open Settings → Devices → **Disconnect device**.
This revokes its account access and keeps its installed software and local files.

To remove Cento software and local data, run `cento uninstall` on that computer.
The CLI previews the installation and asks for confirmation. Use
`cento uninstall --dry-run` to inspect the plan without changing anything.
Your cloud commands, skills, and settings are kept. Local conversation history
and files inside Cento's data directory are deleted; Convex cannot restore them.
Repositories outside that directory and shared tools are preserved.

You can reinstall and pair a new device identity with the same account to use
your cloud configuration again. Settings also provides uninstall instructions
after a device has been disconnected.

## Windows? [#windows]

Supported through WSL2. [Set up WSL](https://learn.microsoft.com/en-us/windows/wsl/install)
if needed, then open your Ubuntu or other WSL2 Linux terminal and run the
command on the [install page](/docs/install). Cento runs inside that Linux
environment; you use the same dashboard and CLI as on any other platform.
