Instead of Facter
Facter alternatives
Facter is a free command-line tool for collecting system details such as hardware, network settings, and operating-system type and version. Built-in facts can be extended with Ruby custom facts or external scripts, and values can retain structured forms such as arrays, hashes, Booleans, and numbers. Fact caching and group blocking let users adjust collection, while Puppet can use the results in manifests and catalog compilation. Facter runs on Linux, macOS, Windows, and self-hosted systems.

Its focus is infrastructure facts, so it may be a less direct fit for people seeking a visual system summary, device diagnostics, sensor readings, or process controls. Adding custom facts calls for Ruby familiarity, and Facter does not create its configuration file automatically. When comparing alternatives, consider whether you need a narrower live view or deeper hardware troubleshooting, and weigh platform support, report formats, monitoring, and integrations against Facter’s custom and Puppet-linked facts.
