The desktop app is the same Mission Control, packaged with Electron. It runs its own local server and adds what a browser cannot do: native UDP and TCP MAVLink sockets, and native pickers for serial and USB devices.

​
Download

Installers are attached to each Mission Control release on GitHub. The installed app is named Altnautica Command.

​
Install

Open the .dmg and drag the app to Applications. The build is not code-signed or notarized, so Gatekeeper blocks the first launch. Open System Settings → Privacy & Security and choose Open Anyway for the app, or right-click the app in Finder and choose Open.

​
What the desktop app adds

Native sockets connect only to local endpoints: loopback, private LAN ranges (RFC 1918), link-local and carrier-grade NAT addresses. The UDP method listens on 0.0.0.0:14550 by default and the TCP method targets 127.0.0.1:5760. The method cards are described on Connect to a drone. Device permissions (serial, USB, geolocation, local network) are granted only to the app’s own local origin.

​
Updates

Every packaged build checks the GitHub releases for a newer version at startup. It never downloads or installs anything on its own. The macOS, Windows and Linux builds are not code-signed, so none of them can install an update into itself: when a newer version exists, a banner reads Version is available. This build cannot install updates itself. with an Open releases link. Download the new installer (or AppImage) from the releases page and install it over the old one. To check again without restarting, open Settings (the General page) and use Check for updates in the About block at the bottom. It reports You are on the latest version. or the newer version it found. A check that cannot reach GitHub, which is normal on a field laptop without internet, shows Could not check for updates with the reason and changes nothing else. A build run from source (npm run desktop:dev) has no release channel: it skips the startup check, and Check for updates reports why it cannot check.

​
Local server port

The app starts its embedded server on 127.0.0.1:4000. If port 4000 is taken, the operating system assigns a free port instead, and the window opens on that port. The app always uses 127.0.0.1, never localhost, because localhost can resolve to the IPv6 address ::1 while the server listens on IPv4.

​
Build from source

Run these from a clone of the repository (see Install Mission Control).
Packaged files land in release/. On macOS, building needs the Xcode command line tools (xcode-select --install).
