Show HN: Openleetcode – local LeetCode runner where tests live in the repo

https://github.com/therepanic/openleetcode
3•therepanic•37m ago
You write a standard solution, just like on LeetCode, and run it through the CLI. It identifies the problem by ID or title, executes your code against local test cases, and shows the result.

It currently supports around 1.4k problems and multiple languages, including Python, C++, Rust, Java, Go, TypeScript, Swift, and others.

The project is still an MVP. System design, SQL, and concurrency problems are not supported yet, but support for more problem types is planned.

Made in Haskell!
