open source · proven in public CI · help when you need it

Infrastructure you have to run yourself, kept current.

Regulation, air gaps and hardware that isn't going anywhere keep a lot of systems off the cloud and off the upgrade path. keelinfra builds open-source tools that keep them supported, and every claim links to a CI run you can check yourself.
