About OS Checker
A monitor that tells you, in seconds, which of your Linux machines need updates - and which of those updates actually matter for security.
Why it exists
Keeping a few Linux machines up to date shouldn't require a monitoring platform. But the alternatives are either general infrastructure monitoring that takes more setup than the problem calls for, or logging in to each machine and running the package manager by hand. Neither tells you, across a mixed set of machines, which pending updates fix a known vulnerability and which releases are about to lose support.
OS Checker does that one job: each machine checks in its OS and installed packages, and the server compares them against each distribution's own repositories and security data.
How it's built
- Security signal over noise. An outdated package and a vulnerable one are always reported separately, and an OS release is always shown as active, maintenance or end of life - never a generic "update available".
- A real command-line tool. The
oscheckerCLI is a single shell script with no dependencies. It checks a machine in every hour and shows the status of all your machines right in the terminal - the web dashboard is optional. - Extensible instead of bloated. Anything else worth tracking goes in a plugin: any executable, in any language, whose output becomes a field on the machine.
Where it stands
OS Checker is in early development. It supports seven Linux distributions today - see Supported OS - and is used on our own machines, but sign-up isn't open yet. If you'd like to try it when it is, join the waitlist.
Who's behind it
OS Checker is built and run by Insytec AB, a software company in Sweden. Questions, feedback and requests for an OS we don't support yet are all welcome at hello@oschecker.com.
