Bot Cloud runtime

Java bot hosting

Run Java bots in isolated containers that draw from one resource pool. You pick the version and the startup file; Hartwell supplies the environment.

Runtime

What you get with Java.

  • Versions

    25, 21, 17. New bots default to 21.

  • Startup file

    Point Hartwell at a file such as bot.jar and it runs it for you.

  • Isolated container

    Each bot has its own memory and storage limits, so one bot cannot take another down.

  • Secrets stay secret

    Set your token and keys as environment variables. Hartwell staff never ask for them.
