Hegel is a universal property-based testing protocol and family of libraries, built on Hypothesis.

Hegel is primarily maintained by Hypothesis developers, as part of their work at Antithesis1. It is our attempt to bring the quality of property-based testing found in Hypothesis to every language. While Hegel will eventually have superpowers inside of Antithesis, Hegel is designed first and foremost to be a family of high-quality property-based testing libraries on its own terms.

Currently, the only Hegel library is hegel-rust. We have libraries in various states of completion for Go, C++, OCaml, and TypeScript, and expect to release some of them soon.
