Production Ready

Why use bOSS containers?

Docker Native

Purpose-built for containerized deployments. No wrestling with dependencies, no "works on my machine" headaches. Just pull and run.

Production Tested

These aren't hobby projects — they power tens of thousands of game servers at Indifferent Broccoli. If something breaks, we find out fast.

Actually Maintained

Game updates break servers. We push fixes within hours, not months. Active development, responsive maintainers, real documentation.

Sensible Defaults

Environment variables for everything. Automatic updates optional. Graceful shutdown handling. We've already made the annoying decisions for you.

Free Forever

Free & Open Source MIT licensed. Use them for personal projects, commercial hosting, or whatever. No license fees, no gotchas, no "enterprise tier" upsells.

Community Driven

Found a bug? Submit a PR. Need a new game? Open an issue. We review contributions regularly and actually merge them.
