# FAQ

> Short answers to common questions about DevHub.

## Which AI clients does DevHub work with?

Claude Code, Codex, Copilot and OpenCode. See [Connect an AI client](/devhub/getting-started/connect-client/index.md).

## Which computers does it run on?

DevHub is an alpha for macOS. See [Requirements](/devhub/getting-started/requirements/index.md). It also needs Git for plans, step trees and repository checks.

## Does my code leave my computer?

Code and notes stay on the computer. DevHub sends Vartari ID only the account sign-in, the device name "Vartari DevHub" and the system. See [How DevHub works](/devhub/concepts/how-devhub-works/index.md).

## Where is the MCP address?

On the [Dashboard](/devhub/features/dashboard/index.md): the MCP server card has **Copy MCP endpoint**. The address is not printed in these pages, and you should not paste it anywhere public.

## Why do I have to sign in?

DevHub shows only the sign-in screen until you sign in with Vartari ID, and the MCP server runs only while a session is active. A session lasts 7 days. Without a network, DevHub keeps working for at most 72 hours. See [Sign in](/devhub/getting-started/sign-in/index.md).

## What does my plan change?

The plan (Standard, Plus, Premium) changes the look; every feature works in every plan. Since 0.8.1 your account also carries a permission for each area, and anything it does not include stays visible but disabled. See [Plans and tiers](/devhub/features/plans-and-tiers/index.md).

## Does closing the window stop DevHub?

No. Closing the window hides DevHub to the menu bar while the MCP server and agents keep working. Use the **Quit** item of the menu bar menu to stop it. See [Settings](/devhub/features/settings/index.md).

## How do I update DevHub?

DevHub checks half a minute after start and every six hours. When a version is available, a banner offers **Download** and **Later**. Nothing downloads or installs without you asking. See [Updates](/devhub/features/updates/index.md).

## Can I use it in Polish?

Yes. Choose the language in Settings > General. A few windows still have English labels: see [Some labels are in English in the Polish interface](/devhub/troubleshooting/untranslated-strings/index.md).

## Where do I find out what is wrong?

Start with [Troubleshooting](/devhub/troubleshooting/index.md). If your case is not there, [write to support](/support/index.md).
