Brobot
Get started

Get started · Mac and Windows

Get the app. Then he's in your world.

The free Brobot app starts a world for the two of you, brings him in and shows what he is doing: his health, a live map, his bags and the chat. Nothing else to install.

Download for Windows Get it on a Mac

You need two things

  • A Mac, or a Windows 10 or 11 PC.
  • Minecraft Java Edition 1.21.11, opened at least once. Brobot runs his world with the Java that Minecraft downloads the first time you press Play. If 1.21.11 is not in your launcher: Installations, New installation, pick release 1.21.11, then press Play once and quit.

  1. On Windows: run the installer

    Download it from the download page and open it. Windows may say it protected your PC, because the app is new and not code signed yet: click More info, then Run anyway. Brobot opens when it is done.

  2. On a Mac: paste one line into Terminal

    Press ⌘ Space, type Terminal and press Return. Paste this line and press Return:

    curl -fsSL https://trybrobot.com/install-app.sh | sh

    It downloads the Brobot app from Brobot's download server, checks its fingerprint against the one published on this site, puts it in Applications and opens it. It never asks for your password, and it installs the app only: nothing else.

    Why a line and not a download button? A Mac only opens a downloaded app without a warning when it is signed with a paid Apple developer ID. Ours is on the way. Until then this line installs exactly the same app, with no warning.

  3. Press Start

    In the app, press the power button. The first time, agree to the Minecraft EULA, which Mojang requires for running a world. The first start downloads Mojang's official server and takes about a minute. The app's home screen then shows the exact address to join.

  4. Join him

    Launch Minecraft 1.21.11 and click Multiplayer, then Direct Connection. If Minecraft shows a caution screen about online play first, click Proceed. In the Server Address box, type the one word below and click Join Server.

    Server Address
    localhost

    That word is the whole address. There is no code or number to add: localhost means "the world on this computer", which is the one Brobot just started.

    Join his world rather than opening yours to LAN: a world opened to LAN checks every player's Microsoft sign-in, and Brobot has no Minecraft account, so Minecraft would turn him away.

    The first person to join becomes an operator. Press T and try "follow me", "mine that" or "build a house".

Next time

Open the app and press Start.

Your world, your settings and everything he remembers are kept between sessions, in a folder called Brobot in your home folder. The app checks for updates when it opens.

Brobot Pro

The Claude brain comes with Pro.

Out of the box he runs on built-in rules, which cover every command on the Commands page. With Brobot Pro, free-form chat goes to Claude: talk to him in plain sentences and he plans the steps himself.

Get it right in the app: open Plans, press Get Pro and pay on Stripe's checkout page. Already bought it on this site? Press Log in with Google in the app with the same Google account. Either way your plan sets itself up and the Claude brain switches on, with nothing to copy or paste.

See what Pro includes

Brobot Squad

Set up your squad.

Squad runs up to four Brobots in your world, each with a job, sharing one base and one memory. Everything happens in the app.

  • Get Squad in the app's Plans screen, or log in with the Google account you bought it with.
  • Add your Brobots. Under Your Brobots in the sidebar, press Add a Brobot, pick a name and a job, and he joins the others. Or press Set up four Brobots in Settings, Account for a full team in one click.
  • The jobs. A builder builds and furnishes the base, a miner brings home coal, iron and diamonds, a farmer runs the farm and cooks, and a guard sticks with you and fights.
  • Talk to them in the app's chat or in Minecraft. Everyone: squad, come here. One of them, by name or job: Digger, get 12 iron or guard, protect me. Anything else goes to the leader.

Questions

Before you ask.

Is the Mac line safe?

Only paste lines from sites you trust. This one downloads the Brobot app from our download server, checks its fingerprint against the one published on this site, copies it into Applications and opens it. It never asks for your password, and nothing else is installed.

How do I update or remove him?

The app checks for updates every time it opens, and Brobot's own updates install by themselves the next time you press Start. To remove him, drag Brobot from Applications to the Bin on a Mac, or uninstall Brobot in Windows Settings, Apps. Your world and his memory stay in the Brobot folder in your home folder until you delete it.

It says Java could not be found.

Open the Minecraft Launcher, press Play on version 1.21.11 once, quit the game, then press Start in the app again. Minecraft downloads its Java the first time a version runs, and Brobot uses that copy.

Why does he need his own world?

Brobot is a separate player. A single-player world only lets in accounts that own the game, so he cannot join one. The app runs a world for the two of you in offline mode, which lets him in under his own name.

Can other people join that world?

No. It listens only on your own computer, because offline mode would otherwise let anyone join under any name.

Can I use a world I already have?

Yes. Stop Brobot, open Settings in the app and press Show next to Brobot folder. Copy your world's folder from your Minecraft saves into the server folder there, named world, replacing the one that is there. Your inventory will not carry over, because the server identifies players differently.

Which Minecraft versions work?

He is built and tested on Java Edition 1.21.11. Bedrock Edition is not supported.

Who can give him orders?

Anyone in the world, unless you change Who can give him orders in the app's Settings and list your Minecraft names. With several players online he only answers when you start with his name.

What happens at night if I am not around?

If he is alone and has no armour, he digs three blocks down, seals the hole and waits for sunrise. When you are with him, he stays and fights.

My laptop went to sleep. Is he gone?

No. Closing the lid freezes the world and Brobot together. When the computer wakes up he carries on, and if the connection dropped he rejoins by himself.

He died. Now what?

He respawns, tells you where it happened, and remembers the spot. Say "get your stuff" and he walks back for it. If you are the one who died, say "get my stuff".
