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

The lead

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.

Why it matters

4k problems and multiple languages, including Python, C++, Rust, Java, Go, TypeScript, Swift, and others. System design, SQL, and concurrency problems are not supported yet, but support for more problem types is planned.
