These tips have been suggested and collected by the community over the years. Hopefully, they'll be helpful to new Battlesnake developers playing the game for the first time!
Be creative with your Battlesnake name and description. Names like "test" or "snek-1" are super popular and are easy to confuse with other developer's Battlesnakes. If you really want your Battlesnake to stand out during competitions, best to give it a creative and unique name.
Web development often means handling multiple requests concurrently, and Battlesnake is no different. It's quite likely your Battlesnake will be playing multiple games at once, and you should develop your web server with that in mind.
Some hosting services like Heroku, Repl.it, and even AWS will de-provision or turn off servers when they're at low usage. For example, free Heroku apps will sleep automatically after 30 minutes of inactivity.
Think about strategies you can deploy to make sure your Battlesnake is awake and running at full speed when you need it most.
The Battlesnake game engine gives each Battlesnake a limited amount of time to respond to API requests - if your Battlesnake takes too long, it could be disqualified from games or the engine could make moves on its behalf.
The amount of time you have to respond is provided in each API request sent. In most cases, it defaults to 500ms, but this value can change in different game modes and tournament divisions.
For most Battlesnake developers this won't be a problem. However top competitors will optimize their Battlesnakes to use as much compute time as possible.
All Battlesnake game logic is open source and available for personal use. If you'd like to run games locally using your own development environment, there's an included CLI.
Install the Battlesnake Rules CLI to get started.
