Ripgrep includes one of the most prominent algorithms from Hyperscan internally for some expressions.

Longer story: Ripgrep uses Rust's regex library, which uses the Aho-Corasick library. That does not just provide the algorithm it is named after, but also "packed" ones using SIMD, including a Rust rewrite of the [Teddy algorithm][1] from the Hyperscan project.
