Have you ever run your own bot? Let us know your favorite script features in the comments!
If you want to run your own bot to manage a room, you generally need a basic understanding of programming or a pre-packaged bot file.
In the older Flash days, scripts were often saved as .hbs files. You would simply open the file, and it would launch HaxBall with the script pre-loaded. This method is becoming obsolete but is still used by some legacy communities.
If you are looking for scripts to help you play better (aimbots or kick macros), you are entering a grey area that ruins the game for others. HaxBall is respected for its high skill ceiling. When a human player makes an incredible save, it is celebrated. When a script makes that save, the replay loses all value.
