About Toolery

Toolery is a small set of free tools for computer science, math, and developer work. Every tool is built to show its working, not just hand back an answer — because the point isn’t just to get a number, it’s to understand where it came from.

The site is free to use and supported by ads. There are no accounts, no tracking beyond basic anonymous analytics, and no data collected from what you type into a calculator.

Toolery is a small, independently run project. New tools are added based on what people actually search for and use, not a fixed roadmap.
