From the README

"There are no magic machines and no magic operators." - DHH openleetcode is a local LeetCode runner built around open test suites, made in Haskell. It takes a normal solution file, finds the matching problem manifest, builds a tiny language-specific harness, sends it to a pluggable execution backend, and judges the result locally.
