The Name

Atrahasis takes its name from an ancient Mesopotamian word meaning "exceedingly wise." The name carries the idea forward: software shaped by that same wisdom — considered, intentional, thoughtful — applied to the craft of modern API work. Where ancient meaning meets the everyday tools of designing, testing, and shipping software.
