About OpsMath

OpsMath is a set of small tools for DevOps, SRE and cloud engineers. Each one answers a single question quickly, like which subnets cidrsubnet() returns or how many pods fit on a node.

It is built and maintained by Hamza El Miqdam, a DevOps and SRE consultant. The tools come from questions that come up again and again on real projects.

How it works

Every tool runs entirely in your browser. There is no backend, no account, and nothing you type is sent to a server. The calculation code is tested against the reference examples from the official documentation of each technology.
