Do I need to install the bot on my phone, console, or PC?
For the hosted website flow, you use the browser to manage a bot running through the service. You do not install the server's bot runtime on your console or treat your browser tab as the bot's hosting process.
Identify the two interfaces you actually use
The website displays setup, linking, access, and supported bot controls. Fortnite displays your real player's lobby, social invitations, selected experience, and game warnings. A browser on your phone can therefore be useful even when Fortnite runs on a different device. Opening the website does not install a playable Fortnite client on that phone, nor does it require your console to run the hosting software used by the service. Keep each interface responsible for the action it actually exposes.
Avoid unnecessary downloads during setup
Follow the controls presented by the public website instead of looking for a worker bundle, command-line engine, or unrelated application to install. Operational downloads used to run service infrastructure are not a first-session requirement for a player. If a third party asks you to download software in order to accept a normal party invitation, compare that request with the official hosted flow before acting. The ordinary setup should be understandable through its browser and Fortnite checkpoints rather than hidden installation instructions.
Know what a browser problem affects
A browser can lose connectivity, fail to load a page, or stop showing fresh information while the hosted bot has a separate connection state. Refreshing the page is a way to recover the control view, not proof that the bot restarted. After recovering the browser, read the panel and the actual party list before sending a new instruction. If the service reports a connection problem, investigate that separately from whether the device displaying the panel needs an update or has a weak connection.
